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.

 0 1 1111122 1111221 1112112 2211111 1121121 2111121 1211112 1211211 1221111 2112111 1112211 1122111 2111212 2121112 2121211 1122222 1122121 1212112 1112122 1112221

Example: The value 0 will be drawn 101010001110 with 1 a black bar, and 0 a white bar / empty space.
