摘要 |
Secured computerized credit cards of the ferromagnetic storage variety, and a computer system that makes use of such cards at more than one location. The card comprises a plurality of ferromagnetic elements, within a continuous ferromagnetic medium, capable of storing binary indicia, sandwiched between thin sheets of plastic or other non-magnetic material. The magnetic elements are tangentially polarized, and locked-in by virtue of two contiguous sheets having different coercivities. Security is provided by programming the information stored on the card in a variety of ways under the exclusive control of the card owner.
