Abstract

In a data transmission system comprising at least one data bank, data may be accessed through a subscriber station. First data should only be accessed by a first authorized range of subscribers, while other data may only be accessed by a second authorized range of subscribers. To this end, the subscriber station includes a reading device enabling data access only if data read from an authorization card to be supplied fulfill predetermined test conditions.

Claims

1. A system comprising an authorization card having track of magnetizable material having information stored therein, a strip having information allocated to the card, said strip being shorter than the card length and said strip having an edge a distance a away from an edge of the card, means for measuring the distance a of said edge of said strip away fom the edge of the card, and means for reading the information content of said strip and said track.

2. A system comprising an authorization card having a track of magnetizable material, a strip having a plurality of punched out areas allocated to the card, said strip being shorter than the card length and said strip having an edge a distance a away from the edge of the card, means for measuring the distance a of said strip away from an edge of said card, and means for detecting punched out areas in the strip, and means for reading the information in the magnetizable strip.

3. A card having a track of magnetizable material, a strip of material having a plurality of perforations as information allocated to the card, said strip being shorter than the length of the card from edge to edge and an edge of the strip being a distance a from an edge of the card, and a magnetizable track having stored thereon information which is dependent on and related to the information allocated to the card stored as perforations and the distance a.
