1. A method applied to an electronic device, wherein the electronic device comprises a plurality of near field communication (NFC) applications, and the method comprises:
obtaining, by the electronic device as the electronic device approaches a first NFC device of a plurality of NFC devices, current scenario information of the electronic device, wherein the current scenario information comprises one or more of geographical location information, time information, weather information, motion information, or usage information, the motion information indicates a motion status of the electronic device, the geographical location information is determined by the electronic device and indicates a geographical location of the electronic device, and the usage information indicates information about the electronic device using NFC applications within a preset time range prior to a time indicated by the time information;
predicting, by the electronic device based on an analysis of the current scenario information performed by the electronic device, a first NFC application group to be invoked and a use order corresponding to the first NFC application group, wherein the first NFC application group comprises n NFC applications of the plurality of NFC applications, n≥2, and n is a positive integer, the use order indicates an order of the n NFC applications in the first NFC application group, and each one of the n NFC applications corresponds to a different one of the plurality of NFC devices; and
sequentially invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group,
wherein each of the plurality of NFC applications has an emulation function of emulating a non-contact integrated circuit (IC) card.
