9. A computer system providing a computerized token identification system using tokens generated by said computer system for uniquely representing a plurality of items, said computer system comprising: a plurality of unique tokens; computer generation means for generating one of said plurality of unique tokens; computer assignment means for associating said one of said plurality of unique tokens with an item; computer recognition means for recognizing said one of said plurality of unique tokens; and computer identification means for identifying the item associated with said one of said plurality of unique tokens, wherein each of said plurality of unique tokens comprises: a delimiter field containing at least one token recognition character; a version field immediately following the delimiter field containing a version string of varying length having at least one character, identifying a unique token version; and a variable field immediately following said version field, containing a variable string of a varying length of at least one character, conforming to a format specification for said unique token version, each variable string being unique for a unique token version, wherein the characters of said version string and said variable string that are adjacent are from different character set types.
10. The system of claim 9 wherein said variable field comprises: a generator identifier field, adjacent said version field, containing a generator identifier string of at least one character, identifying a unique token generator; a verification field, adjacent said generator identifier field, containing a verification character; and an identification field, adjacent said verification field, containing an identification string of at least one character, wherein said identification string is unique for a unique token generator, wherein the generator identifier string and the identification string are of varying lengths, and the characters of the generator identifier string and the identification string that are adjacent are from different character sets.
