Patent

CA 2300621

A method of verifying the validity of a postal stamp to determine whether the stamp is produced legitimately and whether it has been canceled in a previous use. The method includes the steps of producing a special code on the stamp of interest and creating a record relating to the special code in a database. When the mailpiece collected by a post office has a stamp bearing a special code, the special code is reported to the database for verification. If the records in the database indicate that the reported special code does exist, then the stamp is considered legitimate. The mailpiece is accepted and the stamp is canceled before delivery, and a request is sent to the database to effect the alteration of the record relating to the "canceled" special code. An altered record will no longer provide a proof of validity if the database is later consulted with respect to the specific special code.
