What is NFC? In simple terms, by integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, mobile terminals can be used to achieve mobile payment, electronic ticketing, access control, mobile identity identification, anti-counterfeiting and other applications. There are several well-known NFC chip manufacturers in China, mainly including Huawei hisilicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics and so on. These companies have their own technical advantages and market positions in the field of NFC chips. Huawei hisilicon is one of the largest communication chip design companies in China, and its NFC chips are known for high integration and stable performance. Unigoup Guoxin, ZTE Microelectronics and Fudan Microelectronics also performed prominently in payment security, data processing capabilities and multi-application scenarios, respectively. NFC technology is based on the 13.56 MHz wireless communication protocol and enables wireless communication between two NFC-enabled devices no more than 10 cm apart. Very convenient, this connection does not rely on Wi-Fi, 4G, LTE or similar technologies, and it costs nothing to use: no user skills are required; No battery required; No RF waves are emitted when the card reader is not in use (it is a passive technology); With the popularity of NFC technology in smart phones, everyone can enjoy the benefits of NFC.
