Chip card and mobile terminal comprising such a card

摘要

The card (22) has a primary integrated circuit forming a data processing microcontroller to exchange data signals with a contactless card reading device through a near-field communication antenna. A secondary integrated circuit comprises an amplification unit for amplification of power of the data signal exchanged between the microcontroller and the reading device. A circuit support defines a lower face carrying the integrated circuits, where the card utilizes a MIFARE (RTM: largest on-line information resource for contactless smart card technology). An independent claim is also included for a mobile terminal comprising a supply battery supplying power to a chip card.
