摘要

A method of providing a document which can be visually authenticated includes providing a document that is valid for a predetermined period of validity; randomly selecting visual authentication indicia just prior to the period of validity, the visual authentication indicia providing visual indication of validity during the period of validity; and transferring the visual authentication indicia to the document to visually authenticate the validity of the document during the period of validity. The method can be implemented using a system for creating a document which can be visually authenticated disclosed herein. The system includes a plurality of possible visual authentication indicia; a computer capable of executing instructions for randomly selecting one of the plurality of possible visual authentication indicia just prior to a predetermined period of validity; and at least one document validation station for transferring the selected visual authentication indicia to a document to visually authenticate the validity of the document during the period of validity.
