NFC is an acronym for Near Field Communication, which is short-range wireless communication technology. NFC technology can complete a large number of applications, such as information exchange, matching devices to establish Bluetooth/WLAN connections, access control, electronic ticketing, and secure contactless payments. NFC technology can directly read and exchange data without requiring a cumbersome pairing process. In addition, NFC has a peer-to-peer pairing speed, and the pairing speed is less than 0.1ms (which can enhance experience and security), while Bluetooth is about 6 seconds and infrared takes about 0.5 seconds.
NFC devices have been used by many mobile phone manufacturers. In 2017, in the Chinese market, NFC mobile phone sales were 129 million units, an increase of 18.4% year-on-year. At this stage, there are mainly five types of applications of NFC technology on mobile phones:
Such as access control management, tickets and tickets, users can store tickets or gated passwords close to the reader, and can also be used for logistics management. In 2017, among the total sales of NFC mobile phones in the Chinese market, there were 60 million NFC mobile phones that had access through functions.
The user places the device close to the POS machine embedded with the NFC module to make payment and confirm the transaction. In 2017, among the total sales of NFC mobile phones in the Chinese market, there were 56 million NFC mobile phones with contact payment capabilities.
For example, two NFC devices are connected to perform Peer-to-Peer data transmission, such as downloading music, mutual transmission of pictures, and exchange of contacts. In 2017, among the total sales of NFC mobile phones in the Chinese market, there were 114 million NFC phones with contact connectivity.
Users can connect NFC mobile phones to NFC-enabled smart public phones or posters on the street to browse traffic information. In 2017, 708 million NFC mobile phones had contact browsing capabilities in the total sales of NFC mobile phones in the Chinese market.
Users can receive or download information through the GPRS network for payment or access control. For example, a user may send a text message in a specific format to a home helper's mobile phone to control the home attendant's access to the home. In 2017, out of the total sales of NFC mobile phones in the Chinese market, 45 million NFC mobile phones had download and contact functions.
