1, NFC is the abbreviation of near field communication, which is a communication connection mode between devices, similar to Bluetooth connection, and can be used to transmit data;
2. Compared with Bluetooth, the pairing speed of NFC is faster, and the signal handshake can be completed by touching between devices;
3. However, compared with Bluetooth, the effective distance of NFC is relatively short, and it is mainly used for functions such as access card simulation, point-to-point identification, etc., such as bus card simulation recharge, Bluetooth headset and mobile phone pairing, etc.
