Abstract

L'invention concerne un procédé permettant de modifier et/ou d'étendre l'ensemble d'instructions (LECTURE, ECRITURE) d'une carte à puce (1). Pour cela, on utilise les tables d'attributs (100, 200, 300) associées à certains fichiers et aux commandes de l'ensemble d'instructions existant, de façon à modifier les fonctions des instructions. On peut ainsi implémenter des fonctions non standard sans avoir besoin d'utiliser des instructions supplémentaires, c'est-à-dire des instructions non standard.
