The invention concerns a contactless electronic device (10) such as a card, a label, a ticket or a token, comprising at least an electronic microcircuit (20) arranged in the thickness of a rigid or semirigid support and comprising pads (26) connected to an interface antenna (24) arranged in the thickness of the support, the latter comprising at least two opposite, lower (12) and upper (14), protective sheets. The invention is characterised in that it comprises a stack: of a lower protective sheet (12) whereof the inner face (22) bears at least one electronic microcircuit and at least one interface antenna (24); of an intermediate bonding sheet (14) whereof the two opposite faces lower and upper are provided with adhesive; and of an upper protective sheet (16).
L'invention propose un dispositif électronique sans contact (10), tel qu'une carte, une étiquette, un ticket ou un jeton, comportant au moins un microcircuit électronique (20) qui est agencé dans l'épaisseur d'un support rigide ou semi-rigide et qui comporte des plots reliés (26) à une antenne d'interface (24) agencée dans l'épaisseur du support, ce dernier comportant au moins deux feuilles opposées, inférieure (12) et supérieure (14), de protection, caractérisé en ce qu'il comprend un empilage: d'une feuille inférieure de protection (12) dont la face interne (22) porte au moins un microcircuit électronique et au moins une antenne d'interface (24); d'une feuille intermédiaire (14) de collage dont les deux faces opposées inférieure et supérieure sont munies de colle; et d'une feuille supérieure de protection (16).
