The Codabar Barcode format is used to code mainly numbers. However, it contains 9 other symbols: -$:/+.ABCD
Each character is coded with 7 bands, of simple width (1 = narrow) or large width (2 = thick) alternately starting with a bar and ending with a vacuum.
Example: The value 0 will be drawn 101010001110 with 1 a black bar, and 0 a white bar / empty space.
The Codabar standard does not include a checksum.
The deciphering of the Codabar Code consists in the binary reading of the bands, the detection of narrow and thick ones then in their translation via the coding table.
Example: A message 10001011101 translates 1211211 (1 = narrow, 2 = thick) and corresponds to the number 7
The Codabar barcode has a graphic form composed of lines of 2 different widths (thin and thick).
