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?
