Abstract

A magnetic transaction card, employed for identifying the card holder and recording transactions, is formed with an identification article of nonmagnetic material, and with a layer of magnetic material on the identification article forming a magnetic field along a plane surface thereof. Imprinting means alter the magnetic transaction card so as to form coded indicia detectable visually, by touch and by magnetic sensing devices.

Claims

1. A method of producing a magnetic transaction card and sensing same comprising the steps of applying a layer of magnetic material to first and second layers of plastic material, encasing between said first and second layers a visual identification article, offsetting a portion of the magnetic material of at least one of said first and second layers from a plane adjacent a surface of the remaining portion of magnetic material of said one layer, and detecting the proximity of the magnetic material to the plane by magnetic sensing means.

2. A magnetic transaction card comprising an identification article of nonmagnetic material having visually identifiable indicia thereon;

first and second layers of plastic material having magnetic material embedded in at least one surface thereof, said first and second layers encasing said identification article thereby forming magnetic fields along planes adjacent the surfaces of the magnetic material;

a portion of at least one of said layers of magnetic material being offset from the plane of said magnetic material thereby to provide magnetic detectable indicia adapted to be detected by magnetic sensing means.

3. The magnetic transaction card of claim 2, wherein said magnetic material comprises a mixture of high and low coercivity materials.

4. The magnetic transaction card of claim 2 wherein said plastic layer associated with said offset magnetic material is opaque and resilient and only temporarily deformed during the offsetting, said opaque layer returning to its original position following such offsetting thereby concealing the magnetic material marking.
