DUAL-INTERFACE NFC TAG DEVICE AND PAYMENT INFORMATION SHARING METHOD USING DUAL-INTERFACE NFC TAG

摘要

The present invention relates to a dual-interface NFC tag device and a payment information sharing method using a dual-interface NFC tag. The present invention enables a smart device to check the access address number recorded in an access address flag area of the dual-interface NFC tag and record payment information in a data area of the corresponding access address number to enable an electronic device to read payment information from the access address number of the data area, thereby enabling the payment information to be shared between the electronic device and the smart terminal. The dual-interface NFC tag device includes: a port unit including a first port for recognizing the tagging of the smart terminal, a second port for recognizing the data recording from the smart terminal, and a third port for transmitting and receiving the payment information with the electronic device; a first memory unit including the access address flag area which stores the access address number to record the payment information and a recording count number and the data area for recording the payment information; and a main control unit (MCU) which recognizes the tagging of the smart terminal when a repeated toggle-up is detected after a predetermined time elapses while a signal wave is toggled up and down in the first port, recognizes the toggle-down and repeated toggle-up of the signal wave toggled up in the second port as a recording operation of the data area, reads the payment information from the corresponding access address number to transmit the payment information to the electronic device through the third port, and counts the number of the payment information being recorded in the data area.;COPYRIGHT KIPO 2016
