Abstract

L'invention concerne une carte à puce destinée à être utilisée avec un système informatique. Cette carte à puce est caractérisée en ce qu'elle présente d'une part un dispositif qui transmet ou peut transmettre au moins une clé de licence à un programme du système informatique, ledit programme interrogeant la carte à puce et nécessitant une clé de licence, et d'autre part une mémoire servant à mémoriser la clé de licence. L'invention concerne en outre l'utilisation d'une carte à puce comme clé électronique et l'utilisation d'un système d'attribution de licence au moyen d'une telle carte à puce.
