What is NFC?
Near Field Communication (NFC) is short for near-field communication technology. There are three modes of operation card analog mode, read/write mode and point-to-point mode. The card analog mode simulates the NFC mobile phone as Smart Card, so that:
1. Implements functions such as mobile phone payment and access control.
2. A mobile phone in read-write mode can read and write NFC labels.
3. The point-to-point mode supports interaction between two NFC devices.
