Abstract

PROBLEM TO BE SOLVED: To increase the number of the usable times of an IC card by extending a communicating distance at the time of exchanging data by a non-contact system in the composite Ic card so as to widen the width of a communicating frequency band. SOLUTION: When the IC card 1 incorporates a chargeable battery 6 and the voltage of contact terminals is larger than a prescribed value, namely at the time of exchanging data by a contact style, a data processor is driven by a voltage directly supplied from a terminal device to exchange data and the battery 6 is charged by a supply voltage from the terminal device. When the voltage of contact terminals is smaller than the prescribed value, namely at the time of exchanging data by a non-contact style, an interface circuit 3 for exchanging data with outside and the data processor are driven by the battery 6.

2. Description of the Related Art A composite IC card can be directly supplied with power from a terminal device through a contact terminal when data is exchanged by a contact type, but when data exchange is performed by a non-contact type, Power cannot be directly supplied from the terminal device. Therefore, either a built-in battery or an antenna provided to receive electric power from the outside is required. However, if the battery is built in, the structure cannot meet the ISO standard (thickness 0.76 mm). Therefore, the conventional composite IC card cannot contain the battery, and an antenna is provided to receive power from the outside, The circuit was driven to exchange data with the outside.
