Chip card system

Abstract

Abstract 1. Chip card system with chip cards for use as a money substitute, as an identity card or as a storage medium, with which a single chip card (1) can be used successfully for different application cases, with which different areas of money (11 , 12 ... 1n ), integrated into the chip, or of a function unit are provided for the different application cases, a selection circuit (121) being provided in the chip for the selection of the different areas in the chip, for which circuit a certain selection procedure is fixed, by which it can be ensured that the areas relevant for the application case concerned and only these are assigned, that a processor (12), by which the processes necessary for the different specific application cases are executed, is provided for specific application cases as a function unit, this multifunctional chip card (1) being suitable to act together with an input/output device (2), in which a combination control element permitting activation is provided and into which the chip card (1) can be inserted and which additionally contains a power source for mobile use, and the input/output device (2) being connectable to a wireless transmitting/receiving device (3) for communication with a stationary device, characterized in that the processor (2) is fitted in the chip in a way known per se, in that this stationary device for its part contains a device which, if a plurality of mobile devices are present in the local area concerned, controls a multiple access in a way known per se and, if appropriate, according to a priority list, and in that the input/output device (2) remains in the ready-to-receive state for specific applications and, in response to the reception of a signal from the stationary station, with which the latter transmits an item of application information, automatically sends the required message.
