Abstract:
An NFC card includes an antenna circuit including an antenna coil having at least one magnetic axis, and at least one integrated circuit linked to the antenna circuit. The magnetic axis of the antenna coil is substantially parallel to the plane of the card, and is at an angle of 45°±25° with respect to a longitudinal axis LX of the card. Embodiments of the invention are applicable in particular to SIM-NFC card and SD-NFC cards.
