Abstract

A fraud-resistant machine readable credit card is prepared starting with a credit card blank with all artwork, logotype, and signature panel in place on the card. Permanently encoded data is first added to the card by a hot stamp printing process. In this process, MYLAR* based magnetic tape is impacted by a coded, seated print element and the oxide is transferred to the credit card blank in a pattern of discrete magnetic bits. The coded data is deposited either serially by character or in a parallel printing process. Next, an opaque overlay is bonded to the surface of the card by hot stamping. The overlay is of a formulation such that it both hides the encoded data from view pattern is destroyed if an attempt is made to remove the overlay. Following the overlay, the card can be embossed. *Trademark cf E. I.
