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).
Abstract:
The invention concerns a contactless electronic module designed to be inserted in a contactless chip card cavity. Said module comprises an integrated circuit chip connected to an antenna so as to enable the module to function without contact, said antenna being entirely contained in the module. The invention is characterised in that the antenna comprises at least a conductive winding obtained by cutting out a metallic film, the two ends of said winding being connected to two contact pads of the integrated circuit chip card. Said module is transferred into a contactless chip card cavity such that the integrated circuit chip card is arranged in the base of said cavity. A resin is then injected so as to embed and fix the module in its location.
Abstract:
The invention concerns a contactless smart card comprising inhibiting means. It comprises a card body, an antenna (25) and, connected to said antenna connecting terminals (23, 24), an integrated circuit chip. Said card is characterised in particular in that the connecting terminals to the antenna are further connected to conductive via holes (28) emerging at the card surface, and the junction (26) based on an electrically conductive substance, designed to be removed by scraping when it is first used, is flush with the card surface and connects the conductive via holes.

Abstract:
The invention concerns a contactless electronic device (10) such as a card, a label, a ticket or a token, comprising at least an electronic microcircuit (20) arranged in the thickness of a rigid or semirigid support and comprising pads (26) connected to an interface antenna (24) arranged in the thickness of the support, the latter comprising at least two opposite, lower (12) and upper (14), protective sheets. The invention is characterised in that it comprises a stack: of a lower protective sheet (12) whereof the inner face (22) bears at least one electronic microcircuit and at least one interface antenna (24); of an intermediate bonding sheet (14) whereof the two opposite faces lower and upper are provided with adhesive; and of an upper protective sheet (16).
