Abstract
The document includes a support (10) provided with at least one first (12) and second (14) parts that can move relative to one another, the support including an electronic microcircuit (3) and contactless coupling members (2) electrically connected to the electronic microcircuit (3), and capable of being coupled to an external reading station (5) for establishing a contactless communications with the latter (5). The support also includes detecting elements (20) capable of detecting the relative proximity of the first and second parts independent of the contactless coupling members (2), and securing elements (30) connected to the detecting elements (20) and capable of inhibiting and/or authorizing the activation of the contactless communication according to the relative proximity of the first and second parts thus detected.
