22. The user system as claimed in claim 21, wherein said memory card is configured to cooperate with said first terminal equipment and wherein said first application programming interface is configured to execute said commands from said card link application.

23. The user system as claimed in claim 22, wherein said first application programming interface is further configured to receive and send responses to said card link application.

24. The user system as claimed in claim 21, wherein said memory card is configured to cooperate with a second terminal equipment connectable to said first terminal equipment and wherein said first application programming interface is configured to send said commands received from said card link application to said second terminal equipment.

25. The user system as claimed in claim 24, further comprising:

a second application programming interface provided in said second terminal equipment to receive and execute said commands from said first application programming interface.

26. The user system as claimed in claim 25, wherein said second application programming interface is further configured to receive and send responses to said first application programming interface.

27. The user system as claimed in claim 21, wherein said card link application is provided in said integrated circuit card.

28. The user system as claimed in claim 21, wherein said first terminal equipment is a mobile phone and said integrated circuit card is a subscriber identity module card.

29. The user system as claimed in claim 21, wherein said card link application is configured to provide the other applications in said one of said integrated circuit card and said memory card with any of the following functions:

a function to read data from the other of said integrated circuit card and said memory card;

a function to read and decipher data from the other of said integrated circuit card and said memory card;

a function to write data in the other of said integrated circuit card and said memory card;

a function to cipher and write data in the other of said integrated circuit card and said memory card;

a function to erase data in the other of said integrated circuit card and said memory card; and

a function to perform commands on the other of said integrated circuit card and said memory card.

30. The user system as claimed in claim 21, wherein said card link application is configured to implement any of the following functions:

a function to retrieve information about capabilities of said first or said second terminal equipment in regard to the other of said integrated circuit card and said memory card;

a function to open a logical channel between said integrated circuit card and said memory card;

a function to close said logical channel between said integrated circuit card and said memory card;

a function to retrieve information about the other of said integrated circuit card and said memory card; and

a function to execute commands and receive corresponding responses from the other of said integrated circuit card and said memory card.

37. The method as claimed in claim 30, wherein said card link application is provided in said integrated circuit card.

38. The method as claimed in claim 30, wherein said first terminal equipment is a mobile phone and said integrated circuit card is a subscriber identity module card.

39. The method as claimed in claim 30, further comprising:

configuring said card link application to provide the other applications in said one of said integrated circuit card and said memory card with any of the following functions;

a function to read data from the other of said integrated circuit card and said memory card;

a function to read and decipher data from the other of said integrated circuit card and said memory card;

a function to write data in the other of said integrated circuit card and said memory card;

a function to cipher and write data in the other of said integrated circuit card and said memory card;
