The charger will start sending a wireless charging signal to the device, which will receive it and start charging.
The two functions of NFC and wireless charging seem to have nothing to do with each other, in fact, in principleIt's not that much different, essentially they all use the principle of electromagnetic induction. For example, take the NFC access card for example, the mobile phone can sense the current and encrypted data in the card, the card does not need additional power, and the data exchange of this part of the communication is provided by the electromagnetic field established by the NFC component.Does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large. Wireless charging and reverse wireless charging have become a common feature on high-end mobile phones, which use dedicated coils for radio energy transmission.
