This technology evolved from contactless radio frequency identification (RFID) and was jointly developed by Philips Semiconductors (now NXP Semiconductors), Nokia and Sony. It is based on RFID and interconnection technology. Near Field Communication (NFC) is a short-range high-frequency radio technology that operates at a frequency of 13.56MHz within a distance of 20 cm. Its transmission speed is 106 Kbit/s, 212 Kbit/s or 424 Kbit/s. At present, near field communication has passed the ISO/IEC IS 18092 international standard, ECMA-340 standard and ETSI TS 102 190 standard. NFC uses two reading modes: active and passive.
NFC near field communication technology evolved from the integration of contactless radio frequency identification (RFID) and interconnection technology. It combines the functions of inductive card reader, inductive card and point-to-point on a single chip, and can identify and exchange data with compatible devices within a short distance. The operating frequency is 13.56MHz. However, users who use this mobile payment solution must replace special mobile phones. Currently, this technology is widely used in Japan and South Korea. Mobile phone users can travel all over the country with their mobile phones equipped with payment functions: their mobile phones can be used as airport boarding verification, building access keys, transportation cards, credit cards, payment cards, etc.
