Abstract

A certification identifying medium such as debit card or credit card comprising a substrate preferably made of a paper material, a bar code band printed or layered on the substrate with a material including a magnetic material provided with a specific coercive force and a magnetic record band disposed on the substrate to magnetically record information of the bar code. A mask band made of a non-magnetic material is applied to the substrate to cover at least the bar code band to prevent the visual observation thereof. The bar code band generally comprises a plurality of bar codes which have the specific coercive force different from each other.

Claims

1. A certification identifying medium comprising:

a substrate of a rectangular card shape which is made of a paper material;

a bar code band having a first bar code made of magnetizable material having a first coercive force and a second bar code made of magnetizable material having a second coercive force which is higher than that of the magnetizable material of the first bar code, and said bar code band being disposed on a surface of said substrate with said first bar code being printed at first predetermined positions on said substrate as a binary pattern which is different for each certification identifying medium and said second bar code being printed at second predetermined positions on said substrate as a binary pattern which is the same for all certification identifying medium;

a magnetic record band disposed on a surface of said substrate to magnetically record information of the first and second bar codes; and

a mask band made of a non-magnetic material applied to said substrate to cover at least said bar code band so as to prevent a visual observation of the first and the second bar codes.

2. The medium according to claim 1 wherein said bar code band and said magnetic record band are disposed on front and rear surfaces of said substrate respectively.

3. A certification identifying medium comprising:

a substrate of a rectangular card shape which is made of a paper material;

a bar code band provided by a first bar code made of magnetizable material having a first coercive force and by a second bar code made of magnetizable material having a second coercive force which is higher than that of the magnetizable material of the first bar code, and said bar code band being disposed on a surface of said substrate with said first bar code being layered at first predetermined positions on said substrate as a binary pattern which is different for each certification identifying medium and said second bar code being layered at second predetermined positions on said substrate as a binary pattern which is the same for all certification identifying medium;

a magnetic record band disposed on a surface of said substrate to magnetically record information of said first and said second bar codes; and

a mask band made of a non-magnetic material applied to said substrate to cover at least said bar code band so as to prevent a visual observation of said first and said second bar codes.
