Code 93
CODE 93
Code 93 is a continuous, multilevel Full ASCII bar code which has characters constructed of three bars and three spaces. Each data character bar may be 1, 2, or 3 modules wide. The start/stop character has a 4 module wide bar. The all data character spaces may be 1, 2, 3, or 4 modules wide.
Code 93 uses two check characters, C and K, which precede the stop character.
The first check character ``C'' is the modulo 47 sum of the data character values (See Code 93 Character Set ), and weighting values which increase from right to left, with the last data character first, in the sequence 1, 2, 3, ... 19, 20, 1, 2, 3,...
The second check character ``K'' is also the modulo 47 sum of the data character values (See Code 93 Character Set), and weighting values which increase from right to left, with the ``C'' check character first, in the sequence 1, 2, 3, ... 14, 15, 1, 2, 3,...
DATA = C O D E 9 3 C K
Data Values= 12 24 13 14 38 9 3
C Weights = 7 6 5 4 3 2 1
K Weights = 8 7 6 5 4 3 2 1
Calculate C (1 x 3) + (2 x 9) + (3 x 38) + (4 x 14) +
(5 x 13) + (6 x 24) + (7 x 12) = 484
484 / 47 = 10 remainder 14
C = E
Calculate K (1 x 14) + (2 x 3) + (3 x 9) + (4 x 38) +
(5 x 14) + (6 x 13) + (7 x 24) + (8 x 12)
= 611
611 / 47 = 13 remainder 0
K = 0
