METHOD AND MEANS FOR LIMITING ADVERSE USE OF COUNTERFEIT CREDIT CARDS, ACCESS BADGES, ELECTRONIC ACCOUNTS OR THE LIKE |
摘要 |
<p>A system for rejecting second and subsequent copies of an informationally-equivalent card or badge asserted into a client/server system by processing only those cards having transaction histories recorded thereon by comparison matching a history recorded in a central repository and then rewriting the history on the card and in the repository. The rewritten histories include the current transaction. Counterfeit cards, informationally equivalent to the original card prior to the transaction update of the original card, will be rejected when asserted into the system since their histories mismatch that recorded in the repository. <IMAGE></p> |
