How to use Sony nfc

Near Field Communication (NFC), also known as near field communication, is a short-distance high-frequency wireless communication technology, which allows non-contact point-to-point data transmission between electronic devices (within ten centimeters) to exchange data. This technology is developed from contactless radio frequency identification (RFID), and backward compatible RFID was first developed by Sony and Philips respectively, which is mainly used to provide M2M(Machine to Machine) communication in handheld devices such as mobile phones. Because of the natural security of near field communication, NFC

Technology is considered to have great application prospects in mobile payment and other fields. At the same time, NFC is compared with other wireless communication technologies because of its better security, and it is likened to "secure conversation" between machines by China Internet of Things school-enterprise alliance.

NFC chips have the functions of mutual communication and computing power. The Felica standard also includes encryption logic circuit, and the later standard of MIFARE also adds an encryption/decryption module (SAM).

The NFC standard is compatible with Sony's FeliCaTM standard and ISO 14443 A, B, that is, Philips' MIFARE standard is used. TypeA, TypeB and TypeF are abbreviated in the industry, where A and B are Mifare standards and F is Felica standards.

In order to promote the development and popularization of NFC, the industry has set up a non-profit standard organization-NFC Forum to promote the realization and standardization of NFC technology and ensure the cooperation between devices and services. NFC Forum has hundreds of members around the world, including Sony, Phlips, LG, Motorola, NXP, NEC, Samsung, atoam and Intel. Among them, China members include Meizu, OPPO, Xiaomi, China Mobile, Huawei, ZTE, Shanghai Tanya and Zheng Long, Taiwan Province Province.
