Data carrier with disc shaped carrier structure
First Claim
1. A data carrier for a non-contact data communication with a control station, the control station being provided with a coin handling device, which comprises an encoder/decoder and a slot, and controlling a passage to an area or space by checking and/or changing data of authorization of passage on the data carrier by said encoder/decoder when the data carrier is inserted into said slot of the coin handling device, the data carrier comprising:
- a carrier base structure having the form of a disk adapted to be handled in the manner of a coin by said coin handling device;
a non-volatile, electrically erasable and programmable memory designed to store the data of authorization of passage;
a data sending-receiving unit for receiving data from the control station and transmitting data to the control station;
a liquid crystal display for displaying data;
a central processing unit for making visible on the liquid crystal display the data stored in the memory; and
a solar cell unit for providing power to the liquid crystal display and to the means for making visible the data on the liquid crystal display.

Abstract
A data carrier for a non-contact data communication with a control station controlling a passage to an area or space comprises a carrier base structure, a data sending-receiving unit, a non-volatile, electrically erasable and programmable memory, a liquid crystal display for displaying data, and a solar cell unit for providing power. When the data carrier is approached to the control station, data are received from and transmitted to the control station which checks and/or changes the data content of the memory. A means for making visible the stored data on the liquid crystal display, e.g. a microprocessor, and the liquid crystal display are powered by the solar cell unit. The data carrier can be designed as a disk and handled like a coin. A housing of the data carrier can be provided with a cord wound on a spring acted spool.
