Interleaved 2 of 5 Bar Code Commands
Interleaved 2 of 5 bar coding is used mainly in the distribution industry. Two digits are
encoded: one in the bars and one in the spaces. Ten characters are encoded, each any ASCII
character from 0 to 9 (48 to 57 Dec, 30 to 39 Hex).
The sum of the black bars and spaces becomes the maximum width of two characters.
