RF SMART COMBI-CARD OF FINGERPRINT TYPE AND DEALING METHOD THEREOF

摘要

The present invention relates to a smart combi-card which makes a card payment via wired/wireless communications with a card reader. The RF fingerprint typed smart combi-card of the present invention comprises: a first antenna which receives RF signals emitted by an RF card reader; an RF induced power-supply converter which receives output signals from the first antenna and converts the signal into a DC; an MCU which receives fingerprint information from a fingerprint sensor by means of a power creation of the RF induced power-supply converter, determines whether the fingerprint information is matched with fingerprint information stored in a memory, operates a first switching circuit when the fingerprint information is matched, receives power via a contact-type power-supply converter, receives the fingerprint information from the fingerprint sensor to determine whether the fingerprint information is matched with fingerprint information stored in the memory and operates a second switching circuit when the fingerprint information is matched; the memory which stores a registered fingerprint information; the fingerprint sensor which creates fingerprint information and transmits the same to the MCU; a first switching circuit which is ON/OFF controlled by the MCU; a second switching circuit which is ON/OFF controlled by the MCU; a second antenna which is applied power by the driving of the first switching circuit and transmits/receives data to/from the RF card reader; a smart card chip which transmits card information to the RF card reader by means of the second antenna, or transmits/receives data to/from the card reader by means of a contact-type PCB by the driving of the second switching circuit; and a contact-type PCB which is supplied power by contacting with the contact-type card reader, supplies power to the contact-type power-supply converter and controls receiving and transmission of data between the smart card chip and the contact-type card reader when the second switching circuit turns ON.
