Code 1 bar codes are a 2-dimensional matrix format invented in 1992 by somebody named Ted Williams (probably not the baseball player). It can encode letters, numbers, and special codes of various sorts. There are 8 varieties from 1A to 1H, differing by size; the smallest (1A) holds 13 alphanumeric characters or 22 digits, while the largest (1H) holds 2218 alphanumeric characters or 3550 digits, in a 134 x 148 matrix.
