What is NFC?
NFC stands for Near-Field Communication. It is a technology for contactless data exchange in near-field ranges and is based on high-frequency RFID technology (13.56 MHz). Many of today's smartphones support NFC and are therefore capable of simulating contactless cards for authentication. An NFC device can also act as a reader itself, reading both cards and NFC transponders. NFC also supports peer-to-peer communication (P2P) between two active devices. The major advantage of NFC is its extremely low energy consumption.
