Title:
METHOD FOR AUTOMATICALLY SELECTING NFC EMULATION CARD, ELECTRONIC APPARATUS, AND COMMUNICATIONS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/182064
Kind Code:
A1
Abstract:
A communications system (100) for automatically selecting an NFC emulation card. The communications system (100) comprises: an NFC card reader (102) and an electronic apparatus (101) having an NFC function. The method comprises: the NFC card reader (102) sending third query information upon detecting an NFC radio frequency field of the electronic apparatus (101), the third query information comprising first identification information and a supported emulation card service type; the electronic apparatus (101) determining whether there is a first emulation card corresponding to the first identification information; if so, the electronic apparatus (101) determining whether there is a second emulation card corresponding to the service type; if so, the electronic apparatus (101) sending fourth response information carrying second identification information; the NFC card reader (102) sending card selection instruction information; and the electronic apparatus (101) receiving the card selection instruction information, and sending card selection response information. The technical solution enables the electronic apparatus (101) to automatically select a corresponding emulation card, thereby improving efficiency of NFC payment.
