CONTACTLESS COMMUNICATION SYSTEM USING AN INDUCTION METHOD BETWEEN A TERMINAL AND PORTABLE OBJECTS, COMPRISING TERMINAL FUNCTIONAL TESTING MEANS

摘要

The invention concerns a system wherein a non-galvanic two-way communication is set up by inductive coupling between a terminal (10) forming a data transmitter-receiver terminal and one or several portable objects (14) present in said terminal operating range. The system comprises, associated with the terminal, a testing module (20) comprising a circuit capable of co-operating with the terminal by inductive coupling so as to emulate a communication with a portable object located in said operating range, and the terminal includes functional testing means, capable of discriminating a communication with the test module, in detecting a good communication and a faulty communication with the test module and in producing a fault signal in case of faulty communication. The test module can advantageously be structurally similar to a portable object and remotely powered by the terminal.
