Abstract: An IC card used as an electronic device mounted on terminal equipment performs a mutual authentication process for the main body of the terminal equipment. When mutual authentication for the IC card and the main body of the terminal equipment is successfully performed by the mutual authentication process, the IC card forms transmitting data to an external system containing information associated with the main body of the terminal equipment and information indicating the result of mutual authentication for the main body of the terminal equipment. The data containing information associated with the main body of the terminal equipment and information indicating the result of mutual authentication for the main body of the terminal equipment is transferred from the IC card to the external system via the main body of the terminal equipment when the IC card is authenticated by the external system.

Abstract: A wireless communication system performs wireless transmitting and receiving of data between first and second communication devices. The device transmits from the first communication device to the second communication device a prescribed signal by a prescribed carrier signal having a prescribed carrier frequency. The prescribed signal transmitted from the first communication device is received in the second communication device. The device generates in the second communication device a signal of prescribed frequency which is phase synchronous with the prescribed carrier signal. Transmission data is spread spectrum modulated using the signal of prescribed frequency generated in the generating step. The spread spectrum modulated signal is transmitted from the second communication device to the first communication device. The first communication device receives the spread spectrum modulated signal transmitted from the second communication device.

Abstract: A read request signal containing a command, an address, etc. is subjected to two-phase modulation with the first carrier of a first frequency and the resultant signal is then transmitted to a radio card. After the transmission of the read request signal, the first carrier is kept transmitted to the radio card. Upon reception of the read request signal, the radio card generates a power supply voltage and an operation clock and sends response data to the read request signal to a radio card reader/writer. Unlike in the prior art, therefore, the reception of power or the reception/transmission of data need not be performed intermittently so that a large amount of data can be received or transmitted continuously at a high speed.
