NFC chips have the function of mutual communication and computing power. The Felica standard also contains encryption logic circuits. The later standards of MIFARE also added encryption/decryption modules (SAM).
The NFC standard is compatible with Sony's FeliCaTM standard, as well as ISO 14443 A and B, which is the MIFARE standard of Philips. In the industry, they are referred to as TypeA, TypeB and TypeF, where A and B are Mifare standards and F is the Felica standard.
In order to promote the development and popularization of NFC, the industry has created a non-profit standard organization - NFC Forum, to promote the implementation and standardization of NFC technology and ensure collaboration between devices and services. At present, NFC Forum has hundreds of members worldwide, including: SONY, Philips, LG, Motorola, NXP, NEC, Samsung, atoam, Intel, among which Chinese members include China Mobile, Huawei, ZTE, Shanghai Tongyao and Taiwan Zhenglong.
