Abstract

L'invention concerne une carte d'identification, notamment une carte de crédit qui comprend une partie visuelle (b) comportant une photo du détenteur de la carte et dans laquelle des points d'image point par point, d'absorption différente, notamment les composantes grises et noires, sont gravés à l'aide d'un faisceau laser dans la couche protectrice (1) et/ou dans une couche intermédiaire (2) sous une couche protectrice (1) transparente de ladite carte d'identification. Cette dernière comprend en outre une partie en couleur (BF) appliquée sur la photo, de manière à coïncider avec celle-ci, notamment par transfert de chaleur. Des caractéristiques anti-utilisation frauduleuse peuvent également être introduites dans la répartition de l'image.
