Abstract

L'invention concerne un support de données répondant aux normes CD ou DVD mais se présentant sous la forme d'une carte de visite et possédant en outre la fonctionnalité d'une carte à transpondeur. Ce support de données peut être lu, entre autres, dans des appareils de lecture à tiroir, en raison de la présence d'une arête de centrage (5). Ce support de données présente une épaisseur d'environ 1,3 mm à l'intérieur de l'arête de centrage (5) et une épaisseur d'environ 0,4 mm seulement à l'extérieur de l'arête de centrage. Il comporte deux couches (1, 2), la première (1) présentant des zones de données selon la norme CD ou DVD, et la deuxième (2) se présentant sous la forme d'une carte à transpondeur pourvue d'un circuit intégré (10) et d'une antenne. Les deux couches (1, 2) sont réalisées séparément et assemblées par collage ultérieurement, ce qui rend économique la fabrication de ce support de données. La deuxième couche (2) étant réalisée en PVC, ce support de données présente une meilleure résistance à la rupture que les supports de données connus de ce type.
