NFC is a high frequency used to transmit signals. Wireless charging frequency is low, used to passTransmission capacity. So there's no connection. NFC, the Chinese name is near Field communication. It is a short-range high-frequency radio technology evolved from contactless radio frequency identification RFID, jointly developed by Philips Semiconductor, Nokia and SONY, based on RFID and interconnect technology.
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. Now the NFC Forum has announced the approval of a wireless chargerElectrical specifications, allowing users to wirelessly charge devices through NFC chips.
No, mobile phone wireless charging and NFC has no relationship. The parts in the wireless charging of the mobile phone are called wireless collars, and only the mobile phone with the wireless collar can be charged wirelessly.
The two functions of NFC and wireless charging seem to have nothing to do with each other, in fact, there is no difference in principle, in essence, they all use the principle of electromagnetic induction. For example, take the NFC record access card for example, the mobile phone can sense the current and encrypted data in the card, the card does not need additional power, this part of the communication dataThe exchange is provided by the electromagnetic field established by the NFC component.Not through NFC, wireless charging technology is derived from radio energy transmission technology, which can be divided into two ways of low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
Doesn't matter. NFC is high frequency. It's used to transmit signals. Wireless charging is particularly low frequency. The power is also high.
