Abstract

An IC card includes a communication unit and a controller. The communication unit can communicate with one communication destination by a plurality of interfaces including a first interface and a second interface. The controller processes a command received by the communication unit, and makes the communication unit transmit a response to the command. In a case where the first interface becomes unavailable after the communication unit receives the command by the first interface until the communication unit transmits the response to the command, the controller makes the communication unit transmit a response containing discontinuation information indicating that the transmission of the response to the command received by the first interface is discontinued by the second interface.

Claims

1. An IC card comprising:

a communication unit that communicates with the same communication destination by a plurality of interfaces including a first interface and a second interface; and

a controller that processes a command received by the communication unit and makes the communication unit transmit a response to the command,

wherein the controller makes the communication unit transmit a response containing discontinuation information by the second interface in a case where the first interface becomes unavailable after the communication unit receives the command by the first interface until the communication unit transmits a response to the command, the discontinuation information indicating that the response to the command received by the first interface is discontinued in transmission.

2. The IC card according to claim 1,

wherein in a case where the first interface becomes unavailable after the communication unit receives a command by the first interface until the communication unit transmits a response to the command, and the communication unit receives an arbitrary command by the second interface, the controller makes the communication unit transmit a response containing the discontinuation information as the response to the arbitrary command by the second interface.

3. The IC card according to claim 2,

wherein the controller makes the communication unit transmit the response containing the discontinuation information as the response to the arbitrary command in a case where the arbitrary command is normally ended.

4. The IC card according to claim 1,

wherein the controller makes the communication unit transmit a response containing the discontinued response by the second interface in a case where the communication unit receives a specific command to request for transmitting the discontinued response by the second interface.

5. The IC card according to claim 4,

wherein the controller stops transmitting the response containing the discontinuation information by the second interface after executing the specific command.

7. A portable terminal comprising:

the IC card according to claim 2;

a plurality of interfaces that includes a third interface and a fourth interface which communicate with the IC card by the first interface and the second interface; and

a terminal controller that controls transmission of the command by the third interface toward the first interface, and transmission of the arbitrary command by the fourth interface toward the second interface.

8. The portable terminal according to claim 7, further comprising:

a terminal controller that controls transmission of a specific command by the fourth interface toward the second interface after the arbitrary command is transmitted by the fourth interface toward the second interface.

6. An IC card comprising:

a communication unit that communicates with the same communication destination by a plurality of interfaces including a first interface and a second interface; and

a controller that processes a command received by the communication unit and makes the communication unit transmit a response to the command,

wherein the controller makes the communication unit transmit a response containing discontinued response by the second interface in a case where the first interface becomes unavailable after the communication unit receives a command by the first interface until the communication unit transmits a response to the command, and in a case where the communication unit receives, by the second interface, a specific command to request for transmitting the discontinued response to the command received by the first interface.

9. A portable terminal comprising:

the IC card according to claim 6;

a plurality of interfaces that includes a third interface and a fourth interface which communicate with the IC card by the first interface and the second interface; and

a terminal controller that controls transmission of the command by the third interface to the first interface and transmission of the specific command to the second interface by the fourth interface, the specific command requesting for transmitting a response which is discontinued to the command.

10. A portable electronic apparatus comprising:

a main body that is provided with an antenna; and

an IC module that is embedded in the main body and provided with a contact portion,

wherein the IC module includes a contact communication unit that communicates with a terminal in a contact manner using the contact portion,

a contactless communication unit that communicates with the terminal in a contactless manner using the antenna by a magnetic field generated from the terminal, and

a controller that transmits information related to a contactless manner communication by the contactless communication unit to the terminal by the contact communication unit in a case where the contactless communication unit receives the magnetic field when the contact communication unit communicates with the terminal in the contact manner.

11. The portable electronic apparatus according to claim 10,

wherein the information related to the contactless manner communication by the contactless communication unit includes information for specifying a communication manner.

12. The portable electronic apparatus according to claim 10,

wherein the controller transmits the information related to the contactless manner communication by the contactless communication unit as an initial response to the terminal.
