摘要： PROBLEM TO BE SOLVED: To prevent a malfunction, etc., due to a short circuit between power terminals for non-contact operation and to vastly enhance security. SOLUTION: In a dual way type IC card using both non-contact/contact operations, a transistor for separation is provided between a power supply voltage terminal VCC and a contact power supply circuit 15. The non-contact/contact determination switching part 6 turns the transistor OFF and separates the power supply voltage terminal VCC from the contact power supply circuit 15 in detecting that the IC card is the non-contact operation. Thus, when the power supply voltage terminal VCC and a ground terminal GND are short-circuited for the non-contact operation, the malfunctions of the IC card, etc. are surely prevented. Since the power supply voltage terminal VCC becomes a reference potential VSS level in this case, voltage monitor of the power supply voltage terminal VCC is prevented from malfunctions and the security of the IC card is vastly enhanced.
