ABSTRACT:
Secured computerized credit cards of the ferromagnetic storage variety, and a computer system that makes use of such cards at more than one geographic location. The card comprises a plurality of ferromagnetic elements, capable of storing binary indicia, sandwiched between thin sheets of plastic or other non-magnetic material. Security is provided by giving names to the two faces and four edges of the card and using said names to determine any one of eight ways which can be selected by the card owner for inserting the card into the computer and hence of programming the information stored on the card. Only the card owner knows the adopted name and an imposter has only one chance in eight of properly inserting and using the card. Optional means is also provided whereby the card owner can from time-to-time change the adopted card identification name. Means is likewise provided whereby the card-issuing agency can secure the issue of the card and the card's continued use and thereby prevent forgery.
