Abstract
Abstract This invention relates to a plastic identification card. A magnetic encoding panel is printed, preferably by screen printing. This enables the magnetic encoding panel to be applied more economically than with conventional magnetic tapes. The printing of the magnetic encoding panel is applied to a drop out area in the transparent protecting coating, followed by polishing both of the protective coating and the printed magnetic encoding panel. This greatly increases the passes through a reader prior to failure of the magnetic encoding panel.

Claim 1
Independent Claim
56 words
A method of making an identification card having a magnetic encoding panel comprising the steps of applying a protective film to a core stock to leave a drop out area, printing a magnetic encoding panel on said core stock in said drop out area, and polishing both the protective film and the printed magnetic encoding panel.
Claim 2
Independent Claim
56 words
A method of making an identification card having a magnetic encoding panel comprising the steps of applying a protective film to a core stock to leave a drop out area, printing a magnetic encoding panel on said core stock in said drop out area, and polishing both the protective film and the printed magnetic encoding panel.
Claim 3
Dependent Claim
15 words
A method as in claim 1, in which the polishing is with heat and pressure.
Claim 4
Dependent Claim

An identification card comprising a core stock and on one surface thereof a protective coating applied to leave a drop out area, a printed magnetic encoding panel in said drop out area in direct contact with the core stock and having substantially the same thickness as said protective coating, both said protective coating and magnetic encoding panel being polished.
Claim 5
Dependent Claim
59 words
An identification card comprising a core stock and on one surface thereof a protective coating applied to leave a drop out area, a printed magnetic encoding panel in said drop out area in direct contact with the core stock and having substantially the same thickness as said protective coating, both said protective coating and magnetic encoding panel being polished.
Claim 6
Independent Claim
57 words
