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. 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.

2. 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.

3. 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.
