A near field communication method and related apparatus

Abstract

The application provides a near field communication method and related device. When entering a radio frequency field emitted by an NFC card reading device, the electronic device can receive a probe frame emitted by the NFC card reading device. After receiving the probe frame, the electronic device can send a probe confirmation frame to the NFC card reading device, and the probe confirmation frame can be used to indicate that the electronic device has received the probe frame. After receiving the probe frame, the NFC card reading device can send a notification frame to the electronic device, wherein the notification frame carries device characteristic information of the NFC card reading device. After receiving the notification frame, the electronic device can determine a first NFC analog card from one or more NFC analog cards according to the device characteristic information of the NFC card reading device. In this way, the electronic device can automatically and accurately select a suitable NFC analog card and quickly pop up a card swiping interface of the first NFC analog card, thereby improving the speed and efficiency of NFC card swiping.
