Autonomous integrated-circuit card
First Claim
1. An autonomous integrated circuit card comprising:
- a host interface configured to connect to a physical layer of an integrated circuit card terminal;
a logical external communication interface configured to communicate with a communication device; and
an integrated circuit chip including a unique identifier representing a physical identity of the chip and an application program interface (API) module therein, the integrated circuit chip recognizing a connection with the communication device via an authentication procedure employing the unique identifier of the integrated circuit chip and a unique identifier of the communication device, said integrated circuit chip configured to autonomously provide peer to peer communications with the communication device via the logical external communication interface using the unique identifier of the integrated circuit chip to establish a communication path, independent of the integrated circuit card terminal, to the communication device.

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.
