The present document specifies the interface between the UICC and the terminal. The present document specifies: the requirements for the physical characteristics of the UICC; the electrical interface for exchanging APDUs between the UICC and the terminal@ based on ISO/IEC 7816-3 [11]; the initial communication establishment and the transport protocols for this interface; a model which serves as a basis for the logical structure of the UICC APDU interface; communication commands and procedures for the UICC APDU interface; application independent files and protocols for the UICC APDU interface. The administrative procedures@ initial card management and optional communication interfaces between the UICC and terminal are not within the scope of the present document.
