Document Type and Number:
WIPO Patent Application WO/2022/083551
Kind Code:
A1
Abstract:
An emulation card switching method, an electronic device, and a communication system. The method comprises: sending first information to an NFC card reader, so that the NFC card reader determines, according to the first information and a protocol supported by the NFC card reader, a first protocol, and executes a service process of the first protocol with the electronic device; if identification information is not obtained when the service process of the first protocol is executed with the NFC card reader, amending protocol information of a first emulation card from the first information to second information; sending the second information to the NFC card reader, so that the NFC card reader obtains the second information from the electronic device, determines, according to the second information and the protocol supported by the NFC card reader, a second protocol, and executes a service process of the second protocol with the electronic device; and if the identification information is obtained when the service process of the second protocol is executed with the NFC card reader, switching, according to the identification information, the first emulation card to a second emulation card corresponding to the identification information. By means of the method, the card swiping efficiency is improved.
