More Information
Summary:An emulated card switching method, an electronic device, and a communication system are provided. The method includes: sending first information to an NFC card reader, so that the NFC card reader determines a first protocol based on the first information and a protocol supported by the NFC card reader, and performs a service process of the first protocol with the electronic device; if no identification information is obtained when the service process of the first protocol is performed with the NFC card reader, modifying protocol information of a first emulated 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 a second protocol based on the second information and the protocol supported by the NFC card reader, and performs a service process of the second protocol with the electronic device; and if identification information is obtained when the service process of the second protocol is performed with the NFC card reader, switching, based on the identification information, the first emulated card to a second emulated card corresponding to the identification information. This method improves card swiping efficiency.
