Abstract: An output terminal has an electronic data item receiving unit, an identification code receiving unit, a determination unit, and an output unit. The electronic data item receiving unit receives an electronic data item. When a person exists within a predetermined range from the output terminal, the identification code receiving unit receives an identification code concerning the person. The determination unit determines whether the identification code received by the identification code receiving unit is authentic or not. When the determination unit determines that the identification code is authentic, the output unit outputs the electronic data item received by the electronic data item receiving unit.

Abstract: A data reader can read data regardless of the position of a radio IC tag. The data reader reads data at a separate position from a radio IC tag provided with a storage unit storing data and a communicating antenna for transmitting the data stored in the storage unit, and includes a reader/writer for generating a modulated signal by modulating a carrier wave and a plurality of antenna units for transmitting radio waves for a read for communicating data with a storage medium by radiating the modulated signal into the air. The reader/writer includes a phase adjustment circuit for changing the phase of a carrier wave.

Abstract: A server comprises an electronic data item receiving unit, an identification code receiving unit, an identification code storing unit, and an electronic data item transmitting unit. The electronic data item receiving unit receives an electronic data item. When a person exists within a predetermined range from an output terminal, the identification code receiving unit receives a first identification code concerning any one of the person and a device used by the person and a second identification code for identifying the output terminal. The identification code storing unit stores therein the first and second identification codes received by the identification code receiving unit, in association with each other. The electronic data item transmitting unit transmits the electronic data item received by the electronic data item receiving unit to a corresponding output terminal based on the first and second identification codes stored in the identification code storing unit.

Abstract: There is provided a game card including an IC device and an antenna that do not reduce uniformity of thickness of the card due to the IC device and the antenna. The game card stores authentication information readable by a reader/writer that emits electromagnetic waves, and includes an IC device for transmitting and receiving data according to a request from the reader/writer, an intermediate member having a space for housing the IC device, and an antenna provided by printing on the intermediate member with conductive ink and connected to the IC device. A front surface member and a rear surface member are joined to opposite sides of the intermediate member by bonding or the like to form the game card.

Abstract: This invention has as its object to allow a-non-contact IC card to accept a frequency band different from the main receive frequency band of the non-contact IC card. The invention has a non-contact IC card which has a main antenna supporting a first frequency band and an IC device connected to the main antenna to perform data transmission and reception processing and an attaching body detachably attached to the non-contact IC card which has a sub-antenna supporting a second frequency band different from the first frequency band. When the attaching body is attached to the non-contact IC card, the sub-antenna can be capacitively coupled to the main antenna.

Abstract: A game chip transmits information in response to an inquiry from a reader/writer. The game chip comprises an IC device, an antenna coil unit, a first ring and a second ring. The IC device constitutes an electromagnetic induction coupling circuit with the reader/writer and stores information. The antenna coil unit is connected to the IC device and generates an induced current by a magnetic flux emitted from the reader/writer to supply power to the IC device when the inquiry is received. The first ring induces the magnetic flux emitted from the reader/writer in one of directions of moving away from and approaching the reader/writer. The second ring induces the magnetic flux induced by the first ring in the other of the directions of moving away from and approaching the reader/writer.
