Abstract
An identification card having information applied in the form of patterns, letters, numbers and/or images, formed by interruptions in the homogeneity of different colored layer areas arranged superjacently on the identification card. The colored information can be produced by selectively removing the color layers by means of a controlled laser beam or by blurring or other chemical reactions induced by said beam. Thus identification cards can be produced having a high standard of security in spite of the simplicity of their production.
