Abstract: An insert for a chip card includes a body provided with a cavity in which is inserted an electronic module provided with a microelectronic chip connected to an inductive or capacitive coupling. The body has a stack of layers at least a first layer of which comprises a first booster antenna and a second layer of which comprises a second booster antenna, the various booster antennas being coupled together inductively and/or capacitively, and at least one of the booster antennas being coupled inductively and/or capacitively with the coupling of the module. The body furthermore comprises at least one metal plate disposed between two layers of ferrite, the first and second booster antennae and the metallic plate being arranged in such a way that at least one of the two booster antennas and the electronic module remain coupled together inductively and/or capacitively, despite the presence of the metal plate.

Abstract: An electronic module for a smartcard has a dual, contact and contactless, communication interface. The module includes an electrically insulating substrate on which are produced electrical contact pads enabling operation via contact with corresponding contacts of a smartcard reader, and contact pads for connection to corresponding pads of an antenna located on the body of the smartcard and enabling a contactless operation with a remote smartcard reader. The substrate is coated with a single electrically conductive layer, especially one made of metal, located on the lower face of the electronic module, and the upper face of the electronic module, which face is intended to be flush with the external face of the smartcard, is produced by said electrically insulating substrate, the latter being provided with windows leaving exposed all or some of said electrical contact pads.

Abstract: The invention concerns a smart card comprising a card body provided with a cavity in which an electronic module incorporating a microelectronic chip is inserted, and at least one security marking designed to authenticate a component of the smart card. A first security marking is disposed on the microelectronic module, and a second security marking is disposed on the card body. The two security markings are linked by a visual identity or matching relationship indicating that the microelectronic module and the card body are original components assembled when the smart card was manufactured.

Abstract: An electronic module with a dual contact and contactless communication interface, has, on a first face, an electric contact terminal for contact with corresponding contacts of a smart card reader, and, on a second face, an antenna with a coil and a microelectronic chip coated with insulating resin and provided with a contactless communication interface. The antenna has a proximal connection pad and a distal connection pad to be connected to the corresponding terminals of the contactless communication interface of the chip. The proximal connection pad and distal connection pad of the antenna are arranged inside the encapsulation area by an insulating resin, in such a way as to produce a conductive bridge between each proximal connection pad or distal connection pad and the corresponding terminal of the chip, directly via connection wires between said connection pads and the corresponding terminals of the chip, without using vias.
