A portable electronic apparatus that is disposed to a portable terminal device includes a contactless communication unit, the apparatus comprises a first interface which performs communication with the portable terminal device a second interface which performs contactless communication by using the contactless communication unit a storage unit which stores a plurality of application programs that execute processing in the contactless communication using the contactless communication unit through the second interface a setting unit which sets an application program capable of responding to an access request in the contactless communication in the plurality of application programs stored in the storage unit and a processing unit by which the application program enabled to respond to the access request in the contactless communication by the setting unit alone responds upon receiving the access request in the contactless communication through the second interface.

Portable terminal system using a contactless communication unit to enable access to application programs

According to one embodiment, an electronic device connected to an authentication device through a first communication network, and further connected to another electronic device through a second communication network, wherein the electronic device executes authentication of the electronic device and another electronic device by data delivery/receipt conforming to a predetermined procedure between the electronic device and the authentication device through the first communication network, and data delivery/receipt between the electronic device and another electronic device through the second communication network.

Electronic apparatus and terminal

A contact less function chip includes a communication control circuit for contact less communication and a memory which stores setting data items of various communication protocols for contact less communication applied to the communication control circuit for contact less communication. When the contact less function chip is mounted on a mobile telephone, it acquires equipment information of the mobile telephone, determines a communication protocol for contact less communication to be preferentially performed based on the equipment information of the mobile telephone and makes a communication setting for the communication control circuit according to setting data of the communication protocol which is determined to be preferentially performed.

An antenna device including a loop antenna main body having a predetermined aperture area, and a conductor element insulated from the loop antenna main body, connected to a ground potential, and formed in parallel with the loop antenna main body.

Removal data storing medium having loop antenna

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.

Wireless communication system and data storage medium

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.
