Bar Code

A bar code is an array of rectangular bars and spaces that are arranged in a way that can be read by the appropriate reader. There are international standards that define how to configure a bar code that is machine readable. When the appropriate reader comes in contact with the bar code, it is able to provide information to software that can convert the information into letters and numbers that provide meaningful information.

Many bar code formats are specific to the individual application of the system. The most common form of a bar code, other that a UPC code, is the 3 of 9 format.

Many industries that use photo identification to apply a bar code on to the photo id. An example of where bar codes can be used are in libraries, cafeterias and lunchroom POS systems to identify the card holder and modify account balances.
