Abstract

According to one embodiment, an IC card which makes a non-contact communication with an external apparatus, includes, 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 IC card from a passive mode to an active mode, a command generation module configured to generate a second command which controls other IC card to execute processing when the first command is the switching request command, a command transmission module configured to transmit the second command to the other IC card.

Claims

1. An IC card 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 IC card from a passive mode to an active mode;

a command generation module configured to generate a second command which controls other IC card 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 IC card.

2. The IC card of claim 1, 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.

3. The IC card of claim 1, further comprising:

a battery; and

a carrier wave output module configured to output carrier waves using electric power of the battery,

wherein the determination module determines based on the switching request command whether or not switching of carrier waves is requested, and

the carrier wave output module outputs the carrier waves to the other IC card using electric power of the battery when switching of the carrier waves is requested.

4. The IC card of claim 1, further comprising:

an IC module comprising the respective modules; and

a main body in which the IC module is arranged.

5. 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.

6. 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 a second command which controls other IC card to execute processing when the first command is the switching request command; and

transmitting the second command to the other IC card.
