Abstract
The invention relates to a chip card with a dual contact and contactless communication interface, including a microelectronic module (11) and a card body (22) provided with a cavity (23) which can receive the microelectronic module, said microelectronic module (11) being formed by a substrate (15), the first face thereof bearing a terminal block of electric contacts (4) and a second face thereof bearing a first microelectronic chip (9) electrically connected to the terminal block of electric contacts (4) and a second chip (10) electrically connected to the terminals of an antenna (13), the coils of which are disposed on the second face of the substrate of the electronic module. The invention is characterised in that the card body (22) includes a device (18) for concentrating and/or amplifying electromagnetic waves, which can channel the electromagnetic flow received, in particular, from a contactless chip card reader toward the coils of the antenna (13) of the microelectronic module (11).
