Abstract
An identification card with high-embossed data, in which the high-embossed data are superimposed by a security pattern which is inscribed in the identification card by means of a laser beam recorder. The security pattern may be present, for example, only on the high-embossed data themselves or else cover a larger area of the card. Attempted back-embossing of the high-embossed data is immediately recognizable due to distortion of the security pattern.
