Abstract
A system is disclosed which permits tokens used for finance to be checked for authenticity by having the tokens display an authentication code that varies with time, yet can be validated by the token validation authority. Because this code changes, it will not be stored and stolen as existing codes are. This reduces fraud for all involved where there is risk that a token might be a forgery.
