Vorrichtung, bestehend aus mindestens einem Kartenendgerät zur Übertragung von Energie zu einer Chipkarte und zum Datenaustausch mit der Chipkarte über elektromagnetische Wellen

摘要

The invention concerns a method and device for adapting chip cards (7) to card terminals (9) which exchange energy and data with the chip cards (7) by means of electromagnetic waves (8, 19), the chip cards (7) comprising an electronic circuit (3, 4, 10, 11), contactless connection means (6) and optionally an electrical energy store (18). The electromagnetic waves (8, 19) emitted by the different card terminals (9) differ from one other in terms of one or a plurality of physical features (frequency, phase, etc.). The chip card (7) can differentiate between the waves (8, 19) received from different card terminals (9) according to these different features, evaluate the waves and, depending on the result of the evaluation, activate different functional parts (CCl1, CCl2, CClX) of the circuit (3, 4, 10, 11). The chip card (7) absorbs energy and exchanges data according to the special function of the functional part activated in each case.
