Kennkartensystem mit verschluesselten Kenndaten

摘要

In an encoded identification card system including means to manufacture the card and means to read the card, the card is produced with a facial image on the card of the person identified by the card. The entire card is produced photographically by preparing a data card including alphanumeric data and encoded data. The data card is then photographed onto the identification card as is the facial image of the person to be identified by the card. The encoded data on the card comprises code patterns along a code track with a timing track containing timing marks indicating when the code track is to be read out. The readout system of the card comprises an optical scanner which scans the code and timing tracks and, in addition, optically scans variable input data provided by the operator of the readout system and fixed input data. The fixed input data is encoded on a second card in the same manner that the data is encoded on the identification card. The variable input data is encoded on slats which are slidable relative to one another and relative to the optical scanning mechanism to place different code patterns in the track of the scanner.
