PURPOSE: A smart card is provided to satisfy the ISO/ICE 7816(international Organization for Standardization/International Electrotechnical Commission) as a contact standard and the ISO/ICE 14443 as a non-contact standard, and to enable a non-contact interface to generate a reset signal and a clock from a wireless signal of a card reader. CONSTITUTION: The smart card(1) includes a CPU(22), a memory(23) and a crypto module(21). The CPU(22) communicates with a system logic circuit(30) through a bus. The system logic circuit(30) intermediates the communication between the CPU(22) and the card reader connecting through a contact interface or a non-contact interface. The contact interface connects contact terminals(P1-P5) with the system logic circuit(30). The non-contact interface connects a non-contact antenna(26) with the system logic circuit(30). The non-contact interface includes the RFC(Radio Frequency Circuit)(40). The RFC(40) detects power, a reset signal, the clock and data(RFI-TX) from the signal received by the non-contact antenna(26), provides it to the system logic circuit(30), and provides the data(RFI-RX) from the system logical circuit(30) to the card reader.
