Bar Code Generating Software

Each bar code has a start bar and an end bar to allow the scanner to read the data precisely. Some bar codes have another bar known as the checksum bar code. After the scanner calculates the sum, it is verified with the value of the checksum bar code for accuracy. This ensures exact calculation with minimal errors.

A number of bar-code-generating software suites are currently available on the market. In order to generate a bar code, the software needs to be installed and certain specifications need to be entered into the software. The most common specifications are the width of the bar code, height of the bar code, spacing between the bars, and symbology. Also, the code word needs to be provided for it to be changed into a bar code format.

Bar code symbology specifies the kind of bar code to be generated. One-dimensional and two-dimensional are the common kinds. Among these there would be subdivisions as to the type of bar code that needs to be created by the software.

Bar code generating software allows the user to easily create a design. The bar code can consist of numbers or alphanumeric characters. Various fonts can be used to distinguish the code while providing a unique touch. A few manufacturers are also experimenting with the graphics within the code, but such experiments require the software to be highly sophisticated to be able to understand it.

Bar code generating software suites come as complete packages that help in the whole process. When the word “whole” is used in this context it includes everything from generating the software to printing labels. Many software suites include the printing software as part of the suite. Since this is included, so too are the printing fonts.

While most can afford to buy bar code generating software, those who cannot can download the software from the Internet. One can also do the work online. Your work can be stored as an image file and used with the printing software to get it onto the labels.

With the software, a minor mistake would be tough to rectify in the later stages due to the unreadability of a bar code. A manual with simple instructions would be provided, which the user needs to go through before starting on a design.

Bar code generating and printing software is available in many varieties. Shopping around would be a good option, as is getting to know all the features of a particular software suite you wish to buy.

Bar Code Labels: A Guide

Bar code labels are tags that contain encoded information. They are used to identify and list inventories in businesses that use a large number of goods. They are made of paper, vinyl, plastic or metal and have an adhesive surface underneath by which they can be affixed to the surface of the item.

Bar code labels use two primary techniques to encode the numerical information on it. One is the line bars technique. Special bar code software can convert an inputted number into a sequence of vertical lines of various thicknesses. The thicknesses of these lines and the spaces between them indicate the number they denote. Another technique is two-dimensional encoding, where information is coded in the form of a pattern of dots of varying thicknesses in a square or rectangular frame. In both techniques, it is not possible by human eyes to decipher what number they indicate.

Bar code labels are designed by software using a computer. Sizes, colors and data fields are placed if required. Once the bar code template is created, it is printed on a specialized paper with an adhesive surface using a printer. Laser printers give good quality outputs, but there are also special standalone printers made expressly for printing bar code labels.

Once the articles are tagged with bar code labels, they get indexed on the database of the company. The bar codes on these labels can be deciphered using scanners. Bar code scanners are small handy devices, which can decode the bar codes into numerical and data information. Scanners can be fixed at a place or handheld.

Companies that have equipment and necessary expertise can design their own bar code labels. This is ideal for companies that produce a large number of goods per day. Some companies even customize their bar codes in order to suit their needs. Smaller companies and temporary businesses can buy preprinted bar code labels from the market. Preprinted bar code labels are available in bundles of hundreds.

Bar codes are very efficient in maintaining large inventory records for companies. It saves a lot of time, as every item is indexed in the register and only a simple scanning procedure enters its records in the required field. The entire process gets systemized and standardized, as a single bar code pattern will be followed for a single product throughout.

The use of bar codes is not limited to consumer products alone, but wherever there is a need of maintaining statistical information. Even consumer bills such as electricity bills, gas bills, maintenance taxes, ID cards bear bar codes.

Bar Code Labels provides detailed information about bar code labels, bar code label printers, bar code label software, bar code label makers and more. Bar Code Labels is the sister site of Bar Code Software.

Image Processing And Bar Codes - Selecting The Right Bar Code With Image Binarization

Documents that are scanned for image processing or storage are often captured at 8 bits per pixel. These are referred to as grayscale images in that 256 levels of gray are able to be represented in the image. The capability to represent shades of gray is required to faithfully capture photographs and graphics but is not normally needed for text. Consequently, scanned images are often binarized.

This process involves the selection of a threshold value and then changing all pixel values below that threshold to black and all pixel values above the threshold to white. This compresses the image by only requiring 1 bit per pixel instead of 8 bits per pixel. For example, an 8.5 inch by 11 inch document scanned at 200 samples per inch, has its storage requirement drop from 3.6 megabytes to 450 kilobytes. Binarization also occurs when documents are transmitted by fax as images are created that are represented with 1 bit per pixel as well.
 

Given a proper threshold, binarized images that contain text can normally still be read by either human eye or OCR algorithms. Indeed, some OCR algorithms begin the OCR process by binarizing the image as the text is typically dark against a lighter background. However, if bar codes are present within the binarized image, they can by altered enough by the binarization process to cause difficulty for a decode algorithm.

The image to the left shows part of the start pattern of a Code 39 linear bar code. The top portion shows the image represented as 8 bits per pixel, while the lower portion shows a binarized version using a threshold of 100. Note that the smooth transitions from white to black in the grayscale image have been transformed into ragged edges that have plus or minus one pixel variability. As a result, the width of each bar or space can vary by plus or minus 2 pixels. Given that the information in linear bar codes is contained in the widths of the bars and spaces, decode problems can result depending on the size and type of the original bar code symbol. The remainder of this article will focus on two issues that should be considered to improve the read rate of binarized bar codes: sample density and symbology type.
 

Sample Density
 

Sample density is the number of samples per unit area that an image is captured. Typical sample densities used for document processing range from 200 to 300 samples per inch (dots per inch or DPI). Fax transmission can vary from 100 up to 400 DPI. In bar code decoding, a more important parameter to consider is the samples per module, where the module size is the size of the smallest feature of the bar code. This distance is also referred to as the X dimension. This parameter includes both the sample density of the image capture device along with the size of the bar code being scanned. Volo™, a bar code decode software toolkit from Omniplanar®, requires a minimum of 1.6 pixels per module for linear bar codes in a grayscale image. From above, if the width of a bar or space can vary by 2 pixels after binarization, one can see that problems can exist in the short widths at this low sample density. Consequently, Omniplanar recommends a typical value of 4 pixels per module for bar codes that will be binarized. For a document scanned at 200 DPI, this requires a minimum module size in the printed bar code of .020 inchs or 20 mils. Increasing the samples per module beyond 4 is also recommended for images that will go through multiple binarization processes such as documents that will be faxed multiple times.
 

Symbology Type
 

The choice of symbology used to encode data should also be considered carefully. Linear (or 1D) bar codes can be broadly classified into two distinct groups: wide/narrow codes and multiple width codes. In a wide/narrow code, each bar or space can only be either narrow or wide. The wide to narrow ratio, which gives the size ratio between the two widths, typically ranges from 2 to 3. Popular symbologies that use only 2 widths include Code 39 and Interleaved 2 of 5. Multiple width codes have more than 2 possible choices for the widths of bars and spaces. Popular symbologies that employ more than two possible widths include UPC and Code 128, both of which allow a bar or space to be either 1, 2, 3, or 4 modules. Given the same samples per module, wide/narrow symbologies typically survive the binarization process with higher read rate performance than their multiple width counterparts. This is simply due to the fact that in the presence of edge variation due to binarization, it is easier to determine if a run is X or 3X wide (where X is the length of a module and an assumed wide to narrow ratio of 3) or if it is 1X, 2X, 3X or 4X as is the case with multiple width symbologies. The table below classifies the linear symbologies supported by Omniplanar’s Volo into the two classes mentioned above.
 

Wide/Narrow
 

  • Codabar
  • Code 39
  • Interleaved 2 of 5
  • Patch Code
    Multiple Width
     
  • Code 128
  • Code 93
  • RSS
  • UPC
     

     

    While wide/narrow symbologies are preferred in applications where binarization will occur, they do not normally have as high a data density (data stored per unit width) compared to multiple width symbologies with the same X dimension. This can be an issue where limited space on the document is provided for the bar code symbol.
     

    2D Symbologies
     

    2D (or two-dimensional) matrix symbologies are typically presence/absence codes. They use a regular grid of possible cell positions, and the presence or absence of a cell in a grid location encodes the data. Two-dimensional symbols have much higher data density than 1D codes as information is stored in both dimensions of the symbol. In addition, they normally provide error correction to provide redundancy in case some cell data values can not be determined. When a 2D symbol is binarized with sufficient samples per module (the size of a grid position), they tend to do better than linear codes as the edge information is not as critical: it is the position of the center of the cell that is more important. Volo requires a minimum of 2.75 pixels per module in a grayscale image for reliable operation. If additional samples per module beyond 2.75 is provided, performance continues to improve and is a good choice for images that will undergo multiple binarizations. A sample density of 5 pixels or more for 2D matrix symbologies gives good read performance after binarization. 2D Matrix codes supported by Omniplanar’s Volo include Data Matrix, QR Code, and Aztec Code.
     

    PDF417 is often referred to as a 2D symbology. However, it is not a true matrix code. It is a stacked linear code, consisting of multiple rows of short linear codewords. It allows bars and spaces to have up to 6 different widths and as such it can be adversely affected by binarization at lower samples per module.
     

    Summary
     

    In applications where scanned documents containing bar codes are to be binarized, read rate performance can be improved by using linear symbologies that employ only wide/narrow choices for bars and spaces along with at least 4 or more pixels per module. Two-dimensional matrix codes are a good choice when binarization is used with a minimumof 5 pixels per module, and they provide the added benefit of increasing data density of the bar code symbol.

    Defining Your Barcode System Requirements Will Give Your Business The Edge It Needs

    Implementing a bar-coding system can be difficult without the care and discipline any serious undertaking requires. That means preparing yourself and your staff for the job at hand and setting aside the time to properly implement the barcode systems that will become an integral part of your overall business information system.

    When designing any business process it's always best to start out with a plan that outlines the steps involved. To start, your team needs to develop a list of requirements. Requirements are statements that define the action or result you want the system to do for you.

    To find your requirements ask yourself and your staff questions such as:

    • What are my bottle necks? (Every business has bottlenecks)
    • How long does my raw material sit around?
    • How long does inventory sit in the warehouse?
    • Is any part of my inventory increasing? If so, why?
    • How much time is spent looking for things?
    • What don't I know about my business?
    • What are my customers biggest complaints
    • What departments or processes are consistently slow, inconsistent, or have quality problems?

    You get the idea. These kinds of questions will lead to opportunities to improve your business information systems and will help you develop your barcode system requirements which are a critical part of most information systems today.

    After you list your requirements you then need to develop 'use cases'. These define the actions that might be taken to accomplish the goal set by the requirement. An example of some use cases might be:

    • The receiving clerk scans incoming material into your database system
    • The order database is updated so the material order status reflects the receiving of goods
    • Labels are printed and made available to receiving

    Most likely your barcode equipment requirements and use cases will grow as you work through this important analysis phase. Spending time up front defining exactly what your company needs, who will do it, and how it will be done will save you lots of headaches and money down the road. In all likelihood you have been doing this already with some of your non-technical business processes. So don't be put off because you're dealing with technology.

    You or an assigned coordinator need to be directly involved in this process if you expect any kind of real success. Technical expertise is not necessary, though having someone involved that understands the technology will bring you benefits upfront and help you through the process, but the priority must stay on the requirements of the business and not the technology itself.

    • Assign someone to be the barcode coordinator.
    • Talk to people in your industry that have barcode systems. They will be happy to discuss what they did and you will benefit from their mistakes.
    • Learn your industry bar coding standards
    • Find out what your suppliers already have in place as far as barcode scanners, printers and systems.

    Make Your Business Run Smoother With The Right Barcode Systems

    We started tracking railroad cars in the 1960's and today we track everything from hospital patient's prescriptions to chain-of-custody crime evidence. Barcode applications are used anywhere information needs to be tracked. In today's world, that doesn't leave much out!

    Barcode tracking software is used in law enforcement to keep track of evidence; who's is it, where was it found, the officer in charge, etc. These applications are basically database programs that manage all the information related to the evidence for a particular case. The best programs give adequate flexibility for designing the labels and printing.

    In the medical industry, keeping track of patient charts has always been a major problem. The reason is clear when you see how many people handle these charts. The design of a medical chart barcode system obviously needs to connect the chart to the person who has checked it out and the time it occurred. This requires a scan of the medical staffer's ID badge and the chart code. A good system then needs to run periodic checks of the chart room to look for the inevitable discrepancies.

    As with any barcode system, having access to solid reporting capabilities is mandatory. What good is information if it it's not easily accessible? Common report queries might be:

    * Active File List

    * Current Location of Files

    * Last Location

    * Time of File at Location

    * Reserved List

    You may have heard the term, "License plate" used in connection with barcodes. This simply refers to the idea that the information in the barcode is a database key that points to more detailed information. Some medical barcode applications are flexible enough to be used in insurance offices as well as hospitals. In these cases the insurance claim number may be used as the key instead of the patient tracking code. You can save your business a considerable amount of money by uses a good quality generic application and modifying it to work in your situation.

    Barcodes make excellent visitor tracking systems and can be quick and easy to use. This is important if you need information about who visited, how long they stayed, and who they visited, and you find it saves you money to have this information entered into a database automatically. Obviously, this would be important in high traffic sensitive areas.

    We also have technology today that has the capability to track items without scanning. It uses radio frequencies to identify objects with attached Radio Frequency ID tags (RFID).

    RFID is much more expensive per unit and to implement than barcodes but in certain situations it makes sense. Take for example an unattended 24/7 equipment room containing very expensive tools. A simple solution is to fit an RFID sensor in the door way that detects the movement of equipment in and out of the room. The door is locked until the technician swipes a bar-coded ID badge or an RFID tag. This way, the system knows who opened the door and what equipment left or returned, and at what time.

    This type of system could be used in unattended medical chart rooms too, but the problem is the number of charts is enormous and would require a relatively expensive RFID tag attached to every single chart; so this would not be cost effective under these circumstances.

    With today's PC technology, easy database tools such as Microsoft Access, barcode label software, and scanners, many barcode applications can be developed easily and cheaply saving businesses an enormous amount of money each year.

    If you are currently paying someone to enter data into a computer you may want to look into the merits of a barcode management system. We have read studies that show barcode scanning is about 10 times faster than a typist and about 10,000 times more accurate!

    Some interesting facts about bar-coding is that almost every company that has installed a barcode system is looking for other places to use it, and the return on investment for an automated data collection system is typically one year, and often substantially less.

    Choosing the Right Barcode Scanner; Laser or CCD

    Barcode scanners have been on the market for a number of years. You can pay as little as $50 for a scanner up to several thousand depending on durability, scan engine and whether it's laser or CCD. How do you choose what barcode scanner is right for you?

    Laser scanners have typically always been more expensive than CCD scanners. Both have advantages and disadvantages. CCD scanners have no moving parts internal like laser scanners. A CCD can take a drop or resist shock more so than a laser scanner. Laser scanners have oscillating mirrors that are subject to wear and mechanical failure. CCD scanners use LED's for illumination and can last ten times as long as laser scanners. CCD scanners have come a long way. They used to only be able to cast a fixed width wide beam and the operator would have to hold the scanner within touching distance to the label to get the barcode to scan properly. Today, CCD's can scan up to 45 scans per second or faster (depending on the model) which is equiviltent to laser scanners.

    Laser scanners are traditional better for long range scanning which isn't always a requirement for people scanning barcodes. I have used both CCD scanners and laser scanners over the years. I would much rather purchase a good CCD scanner knowing that it's going to last me longer and be less resistance to having to repair it from dropping it on my warehouse floor.

    There are many manufacturers of barcode scanners on today's market. Some questions to ask yourself are: What type of environment will I be using this scanner (warehouse, office)? What size/symbology of barcode that I will be scanning? Is long range scanning a requirement in your application?

    These questions will help determine what barcode scanner is right for you.

    Track and Tracing – From Barcode to RFID

    Search for "Tracking & Tracing" and you are overwhelmed by a response from producers, distributors, retailers and consumer organizations. Tracking and tracing is mentioned in one sentence. But there is a small difference between the two; one is focused on the process in which you need to intervene (tracing) the other is needed to manage the first (track).

    Tracing is the main (process) requirement in which a product ought to be traced during the end-to-end food chain. A track is used to fulfill this process. For example, you might want to trace a product when there appears to be an “over” doses of chemicals found in a food sample. In that case you want to trace the origin of the product (and of the fertilizer) – the producer - and all the other retailers which are selling the same product to different customers.

    One innovation in this area is the evolution of the barcode. We are all familiar with this code which looks like a little invisible burglar caught and send behind bars. And that was indeed the function; bar the product so it couldn’t escape.

    This barcode although still sufficient a more intelligent token will speed up the process now that new tracking and tracing requirements have slowed down the same food chain.

    For those of you who have a pet, for example a dog, will know that they have this little chip. You will not find it, but it is there. This chip will not only identify the dog, but will also identity the dog owner, which may change during the dog’s “life cycle.”

    Now that these chips are reduced in price over time, the barcode has innovated to something called the RFID (Radio-Frequency Identification). This RFID uses a chip that you can read from a (long) distance, which is an advantage which speeds up the identification process in the food chain. But you can also add information to it on your way.

    Now this technology is more widely available, new business developers are looking for a new application. There are many more to find…

    The Future For Barcode Reader Manufacturers

    They’re not really the greatest invention of the recent century. To claim such would be an unbelievable hyperbole. But barcode readers have attained, and kept, their place as indispensable tools for many businesses the world over. Though the world in general may not have been revolutionized by their introduction to several industries, barcode readers have made quite a fortune for benefiting enterprises and barcode reader manufacturers alike.

    Indeed, barcode reader manufacturers have enjoyed tremendous and sustained profit by reason of their main products. Barcode readers have become a must in certain fields that demand for the said products has never waned, instead, has experience a steady increase throughout the years. As a result, barcode reader manufacturers are always aiming to discover new applications and improvements for their cash cow.

    The Driving Force Behind Barcode Reader Manufacturers

    Like most industry giants, barcode reader manufacturers discovered a need, and they provided for such a need through their worthy invention: barcode readers.

    Before barcode reader manufacturers started to distribute their products, businesses involved with the identification and verification of items, especially those in minor or major transits, have been fraught with errors and delays. The reason? Everything was being carried out manually, hence the processes are susceptible to human fallibilities.

    Barcode reader manufacturers offered barcode readers to solve these problems. The bread and butter of these barcode reader manufacturers was able to make things more accurate and convenient, resulting in a more efficient and speedy execution of the said processes.

    Barcode Reader Manufacturers And The Developments In The Industry

    Since the time they have started to offer barcode readers for the usage of relevant businesses, barcode reader manufacturers have likewise introduced improvements over the original models. Today, barcode readers come in a variety of forms, care of the many barcode reader manufacturers in the industry.

    Fixed readers, portable batches and portable RF readers are just some of major types of barcode readers that barcode reader manufacturers are currently selling in the market. They come in further variations, of course. Barcode reader manufacturers have also developed scanner-based barcode readers, camera-based barcode readers, and CDD barcode readers for businesses with equally varied needs.

    Barcode reader manufacturers also change the products to conform to current demands. For example, barcode reader manufacturers today offer barcode readers that could decode numeric barcodes. These barcode reader manufacturers also offer barcode readers that could translate barcodes using alphabetic characters. They also offer barcode readers that could identify and verify barcodes with lines of fixed or varying lengths.

    Barcode Reader Manufacturers And The Future

    Judging from history, only good things can be expected from barcode reader manufacturers in the coming years. The leading barcode reader manufacturers of today such as Symbol Technologies, Intermec, Opticon, Argox and American Microsystems, Ltd. Are already positioning themselves for their continued success in the future. They are heavily investing on their research and development departments to come up with better applications and features for the barcode readers they will manufacture for tomorrow.

    It is an exciting time for both interested businesses and barcode reader manufacturers. Fueled by unceasing success, the future does look bright for those tools that have helped boost the efficiency of countless businesses throughout the years.

    Barcode, Move Aside - QR CODE is Here

    Soon we will be pushing flash movies, coupons, MP3 files, good-old text and god knows what else to our cell phones by pointing their tiny built-in cameras to a QR Code, taking a snapshot, and then pressing the SEND button.

    A QR (from “Quick Response”) Code can store a dozen to a few hundred times more data than a barecode.

    Since it can be programmed both vertically and horizontally, a QR Code can be 90% smaller than a barcode.

    QR Codes can be read from any direction. They do not need to be aligned perfectly like a barcode in order to be read correctly.

    Data can be restored even if QR code is damaged or torn partially. Data from a torn barcode cannot be retrieved.

    The revolution is already well underway in Japan and it's just a matter of time before it reaches the American shores.

    Imagine, you are at the supermarket. You see an odd looking bottle of something on the shelf with a QR Code on it.

    You point your cell phone camera at it, take a snapshot and push SEND and presto!

    Soon you are watching a video about how to use the product, its benefits, complete with a 15% discount coupon that you can use right there at the same store!

    McDonald's in Japan has already started tagging their food packages with QR Codes so that the consumers can download all kinds of nutrition information with their cell phones.

    Welcome to the 21st century and make all your marketing plans accordingly.

    Barcode Scanner - How Does it Work

    Barcodes have become a part of our lives. They are on everything from auto parts to your groceries. A barcode is the way things can be traced by a computer. Barcodes and automatic ID systems are the most effective asset a business could have. A barcode is a message that is coded by the length and width of the bars and spaces that are printed in pattern.

    They use the binary code and is essentially just bars and spaces representing ones or zeros. Barcodes are read by sweeping a spot of light over the printed barcode symbol. The light is called a barcode scanner and it will ring the item up or display some information about the product, a barcode with start with a white space and then alternative black and white spaces until needed with a bar. The heights of the bars are simply a technique to try to keep the information within the bar code area. The longer the information that is needed to be coded, the longer the barcode will be.

    The decoder is the most important component of the barcode scanner and it accepts about 33-200 scans per scanning rate to be able to read error free. An automatic discrimination feature on the scanner means that it will pick out what kind of code that it is scanning. In grocery stores you will find that almost every thing as a UPC code. It will read the UPC code or the universal price code and then ring it into your total. There are other parts of the scanner that is as equally important, but what is the purpose of the Barcode Scanner?

    The purpose of a bar code scanner is the fact that it needs to read a hidden message that is coded with the white spaces and black bars and it is vital information. Practically everything will scan into a computer now since out world has been so technologically advanced. Barcodes have also made our world easier to function within.

    Because of barcodes we don’t have to wait in line for everything to be typed up, all you do is scan and go. Everyone who is anyone can use a barcode scanner and it is so easy to learn. It doesn’t take a genius to learn how to work the scanner and you don’t need a degree. In fact, most of the people who are employed at business that use scanners are under the age of 25 or with the extent of a high school education. Bar code scanners are very easily to operate and they are very helpful when it comes to large orders or such because they save so much time. Barcode scanners are just an easy way to find out information.

    Barcode Label-design Software

     

    Barcode label-design software is a complete solution to all your designing needs for barcode labels. A barcode label is the common way to identify a product or asset. The software designs a pattern of black lines of different thicknesses, each unique from the other. Most design software is compatible for barcode label printing applications.

    Label-design software first generates a template, which is the actual format of a barcode label. Once the template is created, it is printed on a specialized paper with an adhesive surface using a printer. All barcode label-design software packages are easy to use. No programming is needed by the user.

    Starting with thousands of predefined label stocks, each package guides you through label design with intuitive menus and help features. You can create labels with constant data, serial numbers, and dynamic data from text files. It is also possible to write notes that do not print and keep them in the scratch area (off of the label). Some packages allow you to link fields and enter dynamic information from the keyboard at print time.

    Barcode label design software is commonly classified into two types: stand-alone menu-driven programs and barcode font programs. The menu-driven programs come with scalable fonts, graphic image import, all popular barcodes, data file import, and easy custom operator interface. A font-based program can select barcode fonts from any word processing program (such as Word, Excel, PageMaker, etc.), independent of operating systems.

    Most barcode label-design software packages available on the market are easy; they enable you to integrate barcode label designing into your business processes. Choosing which one is right for you depends on how comprehensive you want to get. It is always better to use a trial version before you select your barcode label design software solution. A lot of web sites provide barcode label design software downloads.

    How To Read A Barcode Reader

     

    The barcode reader is used for the scanning through the photo detector. The photo detector then extracts the printed barcodes on the surface of the product. They enable the seller to identify the originality of the product. The information that is extracted is enough for the production of the necessary data. This is known to be consisting of the automatic input device equipment. The input device is significant of the barcode signs where the requirement of the recognition of such signs is necessary and there is a possibility of such devices in circulation. These are known to be circulated in the form of the scanning devices.

    To read the barcode

    When the signs are transmitted they can be devised through the photo detector and then the light emitting diode is used for the scan barcodes. They are then absorbed through the device where the bar codes are decoded. There are four types of the different bar code readers where the technology is used for the reading the data encoded. Even the pen type readers are used and the laser type scanners, CCD readers and the camera based readers. In order to read a barcode reader the tip of the pen is dragged. The thick lines of the bar codes are related to the measurements of the photo diode where the intensity is reflected through the source of the light then it is gradually converted in the form of the waves. These waves are converted into the data signals. Then the waveform is thus decoded in the photo diode where they are undergone with the scanner. They then print the Morse code dots and dashes and thereafter they are decoded. The CCD readers are the charge coupled device. These devices undergo the same procedure and then detect the barcodes.

    Conclusion

    The different types of the bar codes are then used for the productivity of the different photo diodes where they carry the significance of converting them into the main productive devices. The inclusion of the procedures in all the devices undergoes a same procedure but the extraction is leaded in the different ways. The use of those signals can be determined in a way through the camera and the pen viewer.

    Barcode Label Adhesives

     

    An integral part of barcode labeling, barcode label adhesive is the substance or material applied to the back of a barcode label to attach it to the surface of a particular item. A barcode label adhesive should be of industrial grade and must have an apply temperature ranging from 40 °F to 250 °F.

    Shear, tack, and peel are among the properties that are critical for barcode label adhesives. Shear represents the measurement of an adhesive's internal strength with which it attaches itself; shear is especially important on curved surfaces. Adhesives with a low shear fall off easily, while high-shear adhesives do not. Tack measures the ability of an adhesive to build an instantaneous bond with the surface on which it is applied. Peel determines the force required to remove a label.

    Barcode labels are available in a variety of adhesive backings, and the application of adhesives depends upon the type of surface and quality of label material. The weight of the adhesive coat varies according to the application requirements. Barcode label adhesives are generally classified into two groups: permanent and removable barcode label adhesives. Most of the barcode applications employ permanent barcode label adhesives. A feature of this type of barcode label adhesive is that it has a strong adhesion to a range of surfaces including paper, plastic, and stainless steel. Permanent barcode label adhesives are generally used for applications where removal is not required or necessary.

    Removable barcode label adhesives are used for barcode applications where the label is temporary. Common examples of removable barcode label are price tags affixed on costly consumer items. The apply temperature of removable barcode label adhesives starts at around 40°F, which is higher than that of the permanent barcode label adhesives. For particular applications, barcode label adhesives are further sub-divided into acrylic, acid-free, cold-temperature, high-temperature, pressure-sensitive, emulsion, food contact, silicone, solvent, rubber, and glove-friendly adhesives.

    Your Face is a Barcode

     

    Themes from this article:

    1. A digital image of a person's face, can be matched against a database of other images.
    2. The potential will exist to track the movements of everyone in a country.
    3. Automatic face recognition is now becoming practical.
    4. Face recognition systems in public places, is a matter for serious concen.
    5. The shock value of the horrific events on September 11 could make many people opposed to excessive security much more tolerant of its implementation.
    6. Information is collected and transferred without Knolouge or permission from the subjects.
    7. Abuse of face recognition may generate additional crimes.
    8. The question is that of proportion, there must be a balance between liberty and control.

    Points inferred indirectly:

    1. And everywhere the ceremony of innocence is drowned the best lack all conviction while the worst are full of passionate intensity.
    2. Technology is intrinsically neutral, how it is used determines if it is a force for good or evil.
    3. The central principle of our culture should be that which makes ours a free democratic society.
    4. One can extrapolate from historical events such as the unclear tests in 1947, that technologies can not be dis-invented or confined to one use.
    5. Data protection Act may apply, providing at least some basic rights, (no other statutory right in English law to personal privacy).
    6. Technology can make surveillance cheaper through automation a some processes.
    7. Freedom is only the perception of being autonomous.
    8. A society can only be considered free where the goverment forces do not have absolute power over the general populace.
    9. Democracy is in part based on the principles that groups can develop views in insolation from goverment.

     

    Summary:

    The main points made in an article:
    Security system impresses US officials, a special report on the terrorism crisis by Stuart Millar published in the Guardian on Tuesday September 25 are summarised as follows:

    American authorities are committed to deploying a relatively new combination of software and surveillance technologies in response to the attacks of September 11th as part of an airport security review.

    The system under consideration, known as FaceIt, is designed to identify known suspects, through comparison of a person's face against a database of facial images, it does not require the cooperation of the subject, and may not even generate irrefutable evidence in adverse conditions, such as those that exist in many airports, which would increase the risk of false identifications.

    This development is being driven by political interests and could be implemented on mass, to form an equivalent to the British ring of steel, supposedly for our safety and protection to help law enforcement track known subjects. But once in place it's use will invariably be extended over time to infringe upon the populous without our consent or knowledge.

    The question is that of proportion there must be a balance between liberty and control. It should be noted that the current increase in the number of youths waring hoods is possibly a direct result of the introduction of CCTV systems.

    Abstract:

    The populace of an informed society would generally resist even the proposal of any potentially repressive technology such as the FaceIt facial recognition system, with the capacity to indiscriminately report on the movements of any subject, especially when these technological developments are being driven by political interests.

    However such fears are currently being circumvented by the stronger feelings of national insecurity, which are also causing fundamental adjustments in political reasoning of the United States authorities whom are by implication encouraging development of technologies previously believed to be technically and socially unjustifiable.

    The United States goverment:

    Is committed to deploying a derivation of traditional surveillance technology, in response to a review of airport security in lite of the attacks of September 11th, as a measure to help prevent simular incidents in the future. This may be a futile gesture as they are looking at technology to identify known suspects, the problem is that this is not very useful as it is the unknown terrorists that the authorities need to be conce ed about.

    Technology:

    This is a relatively new combination of software and surveillance technologies, the basic components of the FaceIt system under consideration have been about for years, the system is designed to identify known people in public, this could be implemented to form an equivalent to the British ring of steel and notwithstanding a highly unlikely series of events resulting in absolute control of this type of technology, invariably it will find other uses. For example, marketing research is frequently carried out via the use of surveys. It would be a trivial matter to use such a powerful security system to generate statistical data for analysing consumer trends.

    This technology may be able to capture and analyse an image of your face, identify you from a see of people, read your face and even infer things from your body language, but the context outside the view of the cameras and the essence of the moment will be lost forever.

    Effectiveness:

    The efficiency of any technology is a function of firstly its inherent advantages over traditional methods and secondly whether its use would solve more problems than it would create.

    Automation of surveillance operations may reduce part of the administration required, through effective communications and more centralised control, than is possible with human surveillance. The implication being that reduction in the time necessary to complete inconsequential tasks (moving paper around) allows more effective use of the staff resources.

    However most law enforcement technologies, including standard CCTV security cameras are only effective with the cooperation of the people, these systems are often useless against those with criminal intent, and this technology does not generate irrefutable evidence in adverse conditions, such as those that exist in many airports, which would increase the risk of false identifications. The problem is that false identification by a person does not involve the implied reputation of technological accuracy.

    Freedom of actions:

    Absolute freedom would require the absence of any controls, legal of otherwise, this would amount to anarchy. Thus despite being free to do as we peace, we would, ironically, not have the ability to act upon our pleasure, as our lives would be consumed with the nauseate of saying alive! This is in direct contrast with what we are able to accomplish with in the restrictions of society, as a result of the opportunities such restriction creates.

    Implications:

    The implications of expediency adopting such systems are numerous fighting terrorism notwithstanding, there are many as yet unresolved questions as to the uses of a system designed to infringe upon the populous without the consent or knowledge of these people whose faces are captured. As logs as there are successive gove ments, that take control and change policies, the uses of such tools will also be continually changing.

    The problems arise when one considers the wider effects that unwanted surveillance may have, fore example democracy is in part based on the principle that groups can develop views in insolation from goverment.

    One can extrapolate from historical events such as the development of Atomic weapons, to save thousands on both sides by ending the second would war without invading Japan The plans for which were stolen be the Union of Soviet Socialist Republics, which started a sequence of events that untimely ended in the current situation where several minor nation have the ability to start a chain reaction that would literary destroy the world.

    Data protection laws:

    The American people have built into there laws safeguards that could reasonable be used to help prevent the uncontrolled spread of privative systems. We in direct contrast have no rights built rights to protect the privacy of information apart from those set into the data protection legislation which maybe a futile gesture as there are get out glasses for anything evan remotely related to law enforcement.

    Innocent Majority:

    Should this severance technology be implemented anywhere, the unique situation will be created where information will be collected and processed without the individual's knowledge and will be used without the individual having consent. The Data protection Act may apply, providing at least some basic rights, (no other statutory right in English law to personal privacy exists).

    Ethical Dilemmas:

    In a stable society the freedom of the individual can not be absolute, there must be a balance between liberty and control. It is conceivable that there would be no civilised society without a govement able to curtail liberty to a reasonable degree. The question is that of proportion technology can be use as a tool for control, however over use of such technologies implies oppression.

    Any technology can effect a society in significant ways. Fore example increasingly travail bits of data are collected, transferred precessed and used without the individual's knowledge, this is a situation in which people can be completely manipulated by technology and it has long been the case that legal decisions lag behind technical developments.

    Conclusions:

    There is an old Buddhist proverb that states "To every man is given the key to the gates of heaven; the same key opens the gates of hell". Words of wisdom and of waing as within computerisation lies such a key.

    The implication is that nearly everything has some kind of cost to it, new technologies are not created instantaneously, so the consequences of such new systems are also not instantaneously realised, if we choose to ignore certain circumstances in fever of expedient action, in the end, the full implications will be realised, unfortunately too late.

    As implied above, the events of September 11th are important, these events have almost certainly changed things forever. The question is that of proportion, this is what will determine whether the have won or not. Especially when these systems are idolised and become more important then the humans that they exist to serve, we know from history that this sequence of events inevitably fall back upon and destroy its makers in the end. Such subject have as yet been sadly lacking in our studies thus.

    Technology is intrinsically neutral, how it is used determines if it is a force for good or evil, if a technology offers savings to one segment of society, some cost may be exacted ageist another. The Bible will teach us that we are to count the !

    cost of our commitments. Is there a price tag for your soul? Jesus asks the most profound question "What does it profit a man if he gains the whole world but loses his own soul in hell forever" Jesus is asking if we have really thought about costs; spiritual and material. (Jesus said, Matthew 16:26).

    As long as we can justify the cost in terms of how it allows us it feel safer, then we are free because we believe the gove ment is curtailing our liberty to allow a better quality of life. However, if as a society we accept invasive methods of protection then we surrender a little more freedom to choose how to five as we see fit and not as other would dictate. This includes the right to life without others watching our every move.
