Host card emulation, HCE)
Host card simulation is a host-based card simulation. At present, there are two ways to realize card simulation in mobile phones equipped with NFC function: one is based on hardware, which is called virtual card mode; One is software-based, called host card mode.
NFC technology
This technology evolved from contactless radio frequency identification (RFID) and was jointly developed by Philips Semiconductor (now NXP Semiconductor), Nokia and Sony * * *, based on RFID and internet technology.
Near-field communication is a short-range high-frequency radio technology, which works within 20 cm, the frequency is 13.56 MHz, and the transmission speed is 106 kbit/s, 2 12 kbit/s or 424 kbit/s. Near-field communication has passed ISO/IEC IS/kloc-0.
function
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.
