IC card, portable electronic apparatus, and controlling method of IC card

A portable electronic apparatus which makes a non-contact communication with an external apparatus, comprising:

• a reception module configured to receive a first command transmitted from the external apparatus;
• a determination module configured to determine whether or not the first command is a switching request command which requests to switch the portable electronic apparatus from a passive mode to an active mode;
• a command generation module configured to generate a second command which controls other portable electronic apparatus to execute processing when the first command is the switching request command;
• and
• a command transmission module configured to transmit the second command to the other portable electronic apparatus,
• wherein
• the command generation module generates an initial setting command required to establish a communication path with the other IC card when the first command is the switching request command, and
• the command generation module generates a second command which controls the other IC card to execute processing when the communication path is established with the other IC card.

A controlling method of an IC card, which makes a non-contact communication with an external apparatus, the controlling method comprising:

• receiving a first command transmitted from the external apparatus;
• determining whether or not the first command is a switching request command which requests to switch the IC card from a passive mode to an active mode;
• generating an initial setting command required to establish a communication path with the other IC card when the first command is the switching request command;
• generating a second command which controls the other IC card to execute processing when the communication path is established with the other IC card;
• and
• transmitting the second command to the other IC card.
