Abstract:
    The invention concerns a contactless integrated circuit card, wherein a card body (12) in the form of a wafer bears an integrated circuit and an antenna (14) enabling remote communication between the integrated circuit and a reception terminal, and wherein the antenna (14), which extends in the card body (12) is made in the form of a winding, over several turns, on a conductor (16). The invention is characterised in that at least a conductive connection bridge (24) is provided connecting at least two antenna (14) turns to reduce the inductance thereof and the connection bridge (24) extends partly in a rupture zone (26) of the card body (12) which is designed to be ruptured when the card is first used to rupture the connecting bridge (10).
