Abstract: When approaching a card reader device, the electronic device receives a near field communication NFC field strength sensing message and indication information, where the indication information is used to indicate an application identifier AID corresponding to a virtual card, and the virtual card is a card that is not activated in the electronic device, or the indication information is an application data packet, and the application data packet does not include information about an AID; and when the indication information is used to indicate the AID corresponding to the virtual card, the electronic device executes a transaction with the card reader device by using the virtual card, and displays information about the virtual card in a first application, or when the indication information is the application data packet, the electronic device does not display the information about the first application.

Abstract: An emulated card switching method, electronic device, and communication system are provided. The method includes sending first information to an near field communication (NFC) card reader which 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, modifying protocol information of a first emulated card from the first information to second information, sending the second information to the NFC card reader which 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, switching the first emulated card to a second emulated card corresponding to the identification information.
