Abstract
An autonomous integrated circuit card includes a logic external communication interface which directly communicates with a communication device connected to an integrated circuit card terminal main body via a network, in addition to a host device interface connected to an integrated card reader/writer via a physical layer. A communication control unit includes a software module which directly communicates with the communication device via the external communication interface. A central processing unit performs authentication via the communication control unit and reads value information stored in a nonvolatile memory. Further, the central processing unit encrypts the read value information by use of an encryption processing unit and directly transmits the encrypted value information to the communication device via the communication control unit and the external communication interface.
