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.

Attempted back-embossing of the high-embossed data is immediately recognizable due to distortion of the security pattern.
