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.
