Abstract
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.
