Abstract: A card body comprises a first card body (ID-1 card 1), a second card body (plug-in card 2) and a third card body (mini card 3). The first card body has a first shape (ID-1 shape). The second card body comprises a second shape (plug-in shape). The first card body encompasses the second card body. The third card body comprises a third shape (mini shape). The second card body encompasses the third card body. The third card body has a cavity for receiving an electronic module. A first boundary separates the first shape (ID-1 shape) from the second shape (plug-in shape), and comprises a first number of apertures (5, 6, 7, 17, 18) and a first number of notches (19 and 20) defining a first mechanical inter-card body coupling strength (link between ID-1 card 1 and plug-in card 2).

Abstract: The invention relates to an integrated circuit card element, comprising a support (1) on which an electrical circuit (2) is produced, an integrated circuit (5) being connected thereto and having an active flip-chip mounted surface (7), said integrated circuit (5) being fixed to the support by a sealing product (6) that is arranged between the active surface of the integrated circuit and the support. The inventive element comprises a reinforcement segment (8) which is fixed on an inactive surface (9) of the integrated circuit opposite the active surface (7).
