Abstract:
Process for exchanging energy and data between a read/write terminal (1) and a chip card (4) with contactless connections and with contact connections (6), wherein energy and magnetic strip data are transferred through contacts from the read/write terminal (1) to the chip card (4) with contact via the contact connections (6) and wherein energy and magnetic strip data are transferred without contact or with contact from the chip card (4) to the read/write terminal (1) by means of electromagnetic alternating fields when the chip card is near the read/write terminal or with contact via the contact connections (6) when the chip card (4) is inserted into the read/write terminal (1), and when the chip card (4) reaches a minimum value of the energy level of the electromagnetic alternating field of the read/write terminal (1), said chip card autonomously activates itself with at least one circuit part (2) of its electronic circuit, whereinupon activation, this circuit part (2) sends out information to the read/write terminal (1) without contact by means of electromagnetic oscillations, wherein the sent-out information contains the data whose content corresponds to the data/information contents of magnetic strip cards, so that when the chip card (4) is manually held in close proximity to a read/write terminal (1), it causes the terminal to transfer the data of the chip card (4) to remotely located devices in the same form as it is also transferred by magnetic strip card reading devices and, due to the fact that the transmitted information is identical or similar, wherein this remotely located device needs not distinguish whether the information comes from a magnetic strip card or from a chip card.
