1. A communication method comprising:
performing, by an electronic device supporting near field communication (NFC) and operating in an NFC reader/writer mode, an NFC communication process between the electronic device and an NFC tag using a first radio frequency parameter;
performing, by the electronic device in the NFC reader/writer mode, the NFC communication process again using a second radio frequency parameter when a preset condition is met, wherein the second radio frequency parameter is different from the first radio frequency parameter; and
when the electronic device successfully performs the NFC communication process using the second radio frequency parameter, storing, by the electronic device, a unique identifier (UID) of the NFC tag and the second radio frequency parameter in association, or writing, by the electronic device, the second radio frequency parameter to the NFC tag; and
wherein the first radio frequency parameter and the second radio frequency parameter each comprise one or more of following: transmit power of sending a radio frequency signal by the electronic device, sensitivity of receiving a radio frequency signal by the electronic device, a modulation mode used during load modulation, a waveform of a carrier, an amplitude of the carrier, a phase of the carrier, or a frequency of the carrier.
