Abstract

Data present on identification cards in a high-embossed form are protected against attempted forgery and falsification. This protection consists in providing on the identification card, along with the data record in a high-embossed form, a second identical data record which may be visually tested without auxiliary means and is inscribed in the identification card by means of a laser recorder.

Claims

1. In an identification card including alphanumeric characters, which are present in high-embossed form so as to be used as a printing block, and further printed information in the form of alphanumeric characters or images, the improvement comprising, said card including, in addition to the high-embossed characters, a set of data with identical information content as said high-embossed characters, this data set being inscribed in the material of the identification card by means of a laser beam so as to be visually recognizable without any auxiliary aids.

2. An identification card as in claim 1, wherein in the area of each high-embossed character there is an identical character applied by a laser recorder.

3. An identification card as in claim 2, wherein the lasered characters are arranged in the immediate vicinity of each corresponding high-embossed character, making it possible to compare the pairs of characters directly.

4. An identification card as in claim 2, wherein each high-embossed character is superimposed by a lasered character identical to it and coinciding precisely with it as its negative image.

5. An identification card as in claim 2, wherein each high-embossed character has an identical lasered character written over it.

6. An identification card as in any one of claims 1, 2 and 3, wherein the lasered characters exhibit, on the card surface, a microrelief coinciding precisely with each character.
