nfc (Near Field Communication Technology)
This technology evolved from contactless radio frequency identification (RFID) and was developed by Philips Semiconductors (now NXP Semiconductors), Nokia and Developed jointly by 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 10 centimeters. Its transmission speeds are 106 Kbit/sec, 212 Kbit/sec or 424 Kbit/sec. 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 readers, inductive cards and point-to-point on a single chip. Able to identify and exchange data with compatible devices over short distances. The operating frequency is 13.56MHz, but users who use this mobile payment solution must replace a specially made mobile phone. This technology is currently widely used in Japan and South Korea. Their mobile phones can be used for airport check-in verification, building access keys, transportation cards, credit cards, payment cards, etc.

NFC? chips have mutual communication functions and computing capabilities. The Felica standard also contains encryption logic circuits. The later standards of MIFARE also added an encryption/decryption module (SAM).
The NFC standard is compatible with Sony's FeliCaTM standard and ISO 14443 A and B, which uses Philips' MIFARE standard. In the industry, they are referred to as TypeA, TypeB and TypeF, where A and B are Mifare standards and F is Felica standard.
In order to promote the development and popularization of NFC, the industry created a non-profit standards organization, the NFC Forum, to promote the implementation and standardization of NFC technology and ensure collaboration between devices and services. NFC Forum has hundreds of members around the world, including: NOKIA, SONY, Philips, LG, Motorola, NXP, NEC, Samsung, atoam, Intel, among which Chinese members include Meizu, BBK vivo, OPPO, Xiaomi, China Mobile, Huawei, Companies such as ZTE, Shanghai Tongyao and Taiwan Zhenglong.
NFC Forum sponsoring member companies hold board seats and include HP, Mastercard International, Microsoft, NEC, Nokia, NXP Semiconductors, Panasonic, Renesas Technology, Samsung, Sony and Visa International organize.
