Abstract

L’invention concerne une carte à puce (1) à double interface de communication à contact et sans contact, comprenant un corps de carte (2) comportant un module électronique (11) disposé dans une cavité du corps de carte et pourvu sur sa face supérieure d’un bornier de contacts et sur sa face inférieure d’une puce microélectronique protégée par une goutte de résine d’enrobage (13), et ledit corps de carte (2) comportant sur une de ses faces une feuille métallique (3) apparente apte à augmenter le poids du corps de carte (2), une couche (7) pourvue d’une antenne (32) de corps de carte, et une couche isolante ferrimagnétique (6) interposée entre ladite feuille métallique (3) et ladite couche (7) d’antenne du corps de carte, caractérisée en ce que ledit corps de carte (2) comporte en outre une couche (5) de matériau électriquement isolant disposé entre la feuille métallique (3) et la couche isolante ferrimagnétique (6), configurée pour absorber des tolérances d’épaisseur du module électronique (11) et de la feuille métallique (3).
