Alternative Title: bar code
Barcode, a printed series of parallel bars or lines of varying width that is used for entering data into a computer system. The bars are typically black on a white background, and their width and quantity vary according to application. The bars are used to represent the binary digits 0 and 1, sequences of which in turn can represent numbers from 0 to 9 and be processed by a digital computer. The presence or absence of a bar of a particular width in a particular position in a sequence is read by the computer as either a 0 or 1. Most such codes use bars of only two different widths (thick and thin), though some codes employ four widths. The numbers represented by a barcode are also printed out at its base.
