The smart card integrated circuit 12a and the access management card integrated circuit 13a are formed in the same circuit formally, but the transmission frequency band used in the smart card circuit differs from the transmission frequency band used in the access management card circuit in detail. Since the carrier frequency of the transmitter / receiver 32 is set differently. As an example, 13.56 MHz is used as the carrier frequency in the smart card circuit and 125 KHz is used as the carrier frequency in the access control card circuit.

The antenna coil 31 executes wireless communication with a card management system capable of receiving information service with the hybrid card according to the present invention, and induces a voltage from the received radio wave signal. That is, the first antenna coil 12b of FIG. 1 has a structure in which a coil for performing wireless communication with a smart card reader (not shown) and inducing a voltage from radio waves radiated from the smart card reader is wound.

The transmitter / receiver 32 includes a demodulation circuit for removing and demodulating a carrier signal from a signal received from the antenna coil 31 and a modulation circuit for modulating data read from the memory 34 by a specified carrier frequency. In the smart card integrated circuit 12a, the carrier frequency is set to 13.56 MHz during modulation, and the access management card integrated circuit 13a sets the carrier frequency to 125 KHz during modulation.

The control unit 33 controls the peripheral circuits so as to decrypt the received data and execute a corresponding program to execute communication with the external card management system.

In the memory 34, user information is stored in a specific area, and a memory structure for dividing an area of the memory and storing allocated card service information including access control in each divided area.

The rectifier 35 rectifies the voltage induced by the antenna coil 31 to supply power to the smart card circuit or the access management card circuit.

The second transmitting / receiving unit 42b executes the modulation / demodulation signal processing for communication with the access management card system. The carrier frequencies of the first and second transmitter / receivers 42a and 42b are set differently, for example, set to 13.56 MHz in the smart card circuit and to 125 KHz in the access control card circuit.

The memory 44 stores user information in a specific area, stores data and programs necessary for access management in the allocated first area, and stores data and programs for a plurality of card services in the allocated second area. In other words, the second area is further divided into areas according to the service type of the smart card.

The antenna coils 41 and 24 perform a role of wirelessly transmitting / receiving radio waves to the smart card system and the access management system.

The controller 43 includes a memory 44 to control peripheral circuits to execute communication with the smart card system and the access management system.
