ABSTRACT:
In a combination of a magnetic card and a printing apparatus therefor, the magnetic card comprises a substrate made of a non-magnetic material, and a printing surface on at least a part of one side of the substrate. The printing surface has a coloring layer, a conductive layer and a protective layer. The coloring layer is located on the one side of the substrate, and the conductive layer is located between the coloring layer and the protective layer. The magnetic card further includes a magnetic recording layer formed on one of the one and other sides of the substrate. Magnetic information is magnetic-recorded on the magnetic recording layer. The printer comprises an electrosensitive unit for discharge-breaking down the protective layer and the conductive layer of the printing surface, into a character pattern corresponding to the magnetic information magnetic-recorded on the magnetic recording layer, to expose at least a part of the coloring layer in at least an area of the protective layer and the conductive layer which is discharge-broken down, thereby indicating the character pattern.
