Abstract: The invention relates to a SIM (2) card in a first format, with an electronic module (4). The card body comprises a score line (6) surrounding the electronic module (4) in order to define the second card format (3). The said score line (6), comprises residual matter thickness that is smaller than the thickness of the card body. The thickness of the residual matter comprises a first thickness (9) over a first part of the score line (6), at least one second thickness (10) smaller than the first thickness (9) over a second part of the score line and at least one residual thickness change zone (11, 17), where the said thickness change zone is a gradual thickness change zone (11, 17) that goes from the first thickness to the second thickness.

Abstract: The embodiments of this invention relate to a smart card (1) comprising the following:—an integrated circuit chip (10),—a primary card body (3) with a first form factor, comprising a slot (5) on the front (7) designed to accommodate the integrated circuit chip (10), wherein the said primary card body (3) also comprises a detachable contour (c1), peripheral to the slot (5), which represents another form factor and defines a secondary card body (11), characterised in that the primary card body (3) has a first thickness (el), between the front (7) and a back (8), and in that the secondary card body (11) has a second thickness (e2), between a front (7, 12) and a back (14), which is smaller than the first thickness (el).
