Patent Images
1. A user system comprising:
- a first terminal equipment;
an integrated circuit card configured to cooperate with said first terminal equipment;
a memory card that communicates with the first terminal equipment through a proprietary protocol that depends on a memory card type;
a card link application provided in said integrated circuit card to establish and manage a secure logical connection between said integrated circuit card and said memory card through said first terminal equipment; and
a first application programming interface provided in said first terminal equipment to receive and execute commands from said card link application and to cooperate with said card link application,wherein said executing commands by the first application programming interface comprises opening the secure logical connection between said integrated circuit card and said memory card on command from said integrated circuit card, sending responses to said card link application, and coding instructions from said integrated circuit card into the proprietary protocol of the memory card.
