NFC technology evolved from contactless radio frequency identification (RFID). The transmission range of RFID can reach several meters, even tens of meters, and can only achieve information reading and judgment. NFC technology emphasizes information interaction. Near field communication operates at 13.56 MHz and within 20 cm, with transmission speeds of 106 Kbit/s, 212 Kbit/s or 424 Kbit/s. The NFC Forum defines three operation modes (PDF): P2P mode: supports mutual communication between two near-field communication devices to realize information exchange and file sharing.
