Abstract
Abstract A computer token identification system uses a plurality of unique tokens to represent a plurality of items. The token architecture consists of a delimiter field, a version field, and a variable field. The delimiter field contains at least one token recognition character. The version field immediately follows the delimiter field and contains the version string of at least one character identifying a unique token version. The variable field immediately follows the version field and contains a variable string of at least one character conforming to a format specification for the token version. Each variable string is unique for a token version. The version string and variable string can be of varying lengths, and the characters of the version string and variable string that are adjacent are from different character set types.
