Nfc technology evolved from contactless radio frequency identification (RFID) and was jointly developed by Philips Semiconductors (now NXP Semiconductors), Nokia and Sony * * *, based on RFID and internet technology. Near Field Communication (NFC) is a short-range high-frequency radio technology, which works within 20 cm, with a frequency of 13.56MHz and a transmission speed of 106 Kbit/ s, 2 12 Kbit/ s or 424 kbit/s. At present, The near field communication has passed the ISO/IEC IS 18092 international standard, ECMA-340 standard and ETSI TS 102 190 standard. NFC adopts active and passive reading modes.
At present, China Mobile has cooperated with China UnionPay to jointly launch a mobile payment joint product-mobile wallet. Handheld NFC mobile phone can realize business consumption, public transportation and access control. It has brought great convenience to work and life.
