Abstract (en)
[origin: JPH08248864A] PROBLEM TO BE SOLVED: To provide a data carrier, from which no real feature cannot be duplicated or copied, such as an identity card, a credit card. SOLUTION: The first diffusible light scattering property is arranged at least in a partial area 5 in a plastic layer according to the surface characteristic of the plastic layer. In the area 5, the surface characteristic, which is formed by a laser means, is locally changed into a shape 3 so as to be provided with the second diffusible light scattering property, and in this area 5, the first information is applied, so that information can be read at least by a certain angle of a field of view without any chromatic reference with the periphery.
