<p>PURPOSE:To check the genineness of a document such as paper money or a credit card by infrared rays. CONSTITUTION:A document checkable in genuineness is constituted by laminating a protective layer 1, a genuineness check area layer 2, a reflection layer 3, a document substrate 4 and a magnetic recording layer 5 in this order or by laminating the layers 1, 2, 3 in this order but laminating only the substrate 4 and the layer 5 in reverse order. This document is formed by bonding the laminate consisting of the protective layer 1, the genuineness check layer 2 and the reflection layer 3 to the laminate consisting of the document substrate 4 and the magnetic recording layer 5 or by bonding the laminate consisting of the layers 1, 2 to the laminate consisting of the layer 3, the substrate 4 and the layer 5. When the document is checked by infrared rays, no erroneous judgement is generated even if a scanning position is shifted from a standard and genuineness can be accurately judged.</p> |
