A series of lines of varying thicknesses that represent alpha or numeric information that can be read by a machine. A wide range of symbologies are available with code 39 and 128 being the most common.
Code 39 (Code 3 of 9) is the most popular symbology for ID, inventory, and tracking purposes. The Code 39 barcode is the easiest to use of alphanumeric barcodes and is designed for character self-checking, eliminating the requirement for check character calculations. It can encode numbers 0-9, the uppercase alphabet A-Z, SPACE, and the following symbols: - . * $ / % . Code 39 is a discrete barcode. This means that a fixed pattern of bars represents a single character. Each character is made up of 9 bars - 3 of which are wider than the others. A single character therefore consists of 5 black bars and 4 white bars.
A denser, more compact symbology that supports the lower 128 ASCII characters. Used whenever space is at a premium. Variable length strings with a mandatory check digit. It has three variations: code set A, code set B, and code set C. The latter is numeric-only and employs simple compression. Each data character encoded in a Code 128 symbol is made up of 11 black or white modules. The stop character, however, is made up of 13 modules. Three bars and three spaces are formed out of these 11 modules. Bar and spaces can vary between 1 and 4 modules wide. The symbol includes a quiet zone (10 x-dimensions), a start character, the encoded data, a check character, the stop character, and a trailing quiet zone (10 x-dimensions).
