The present invention relates to a smart card having a battery type fingerprint sensor. The smart card comprises: a first antenna receiving an RF signal, an RF induced power conversion unit, a contact power conversion unit providing power of a MCU; a third switching circuit on-off controlled by the RF induced power conversion unit; a battery; a MCU driving a first switching circuit or a second switching circuit; a memory; a fingerprint sensor generating fingerprint information and transmitting the same to the MCU; the first switching circuit and the second switching circuit on-off controlled by the control of the MCU; a second antenna exchanging data with an RF card reader; a smart card chip exchanging the data with the RF card reader; and a contact printed circuit board (PCB) allowing the data to be exchanged between the smart card chip and the contact card reader. The smart card can be helpfully used for a smart terminal having weak RF magnetic energy. |
