Structure of a code 93 barcode[edit] A typical code 93 barcode has the following structure: A start character * Encoded message First modulo-47 check character "C" Second modulo-47 check character "K" Stop Character * Termination bar


Detailed Outline[edit] The 48 possible code-93 symbols are as follows. There are actually ( 8 3 ) {\displaystyle {\tbinom {8}{3}}} = 56 combinations that satisfy the coding rules, but one would be confused with the stop symbol in reverse, and the other 7 are unused. Codes 43–46 can be prefixed to alphanumeric values to produce all 128 possible ASCII codes. This is done in exactly the same way as Full ASCII Code 39, but uses reserved codes rather than re-using codes 39–42.

Full ASCII Code 93[edit] Code 93 is restricted to 43 characters and 5 special characters. In Full ASCII Code 93, the 43 basic symbols (0–9, A-Z, "-", ".", "$", "/", "+" and "%") are the same as their representations in Code 93. Lower case letters, additional punctuation characters and control characters are represented by sequences of two characters of Code 93. This encoding is the same as Full ASCII Code 39, except that four special-purpose symbols are used, rather than reassigning $, /, + and %: Code Details Nr Character Encoding     Nr Character Encoding     Nr Character Encoding     Nr Character Encoding 0 NUL (%)U 32 [space] [space] 64 @ (%)V 96 ` (%)W 1 SOH ($)A 33 !
