About Bar Code Cards
Bar code cards are computer boards that contain storage, font macros, and logic for printing barcodes. They are designed for use with slot card, hand held, and fixed mount bar code scanners; bar code software; bar code printers; and other bar coding products. Bar code cards differ in terms of form factor, clock rate, and voltage. Choices for form factor include industry standard architecture (ISA), peripheral component interconnect (PCI), and Versa Module Eurocard (VME). Some bar code cards also carry additional product specifications, or provide special features.
Bar code symbology is an important parameter to consider when selecting bar code cards. These symbologies are essentially alphabets in which different widths of bars and spaces are combined to form characters and, ultimately, a message. Because there are many ways to arrange these bars and spaces, many different bar code symbologies are possible. For example, some bar code cards contain storage, font macros, and logic for printing Codablock bar codes. With Codablock, each row is structured so that it conforms fully to the rules of the basic encodation symbology.
