NFC – Near Field Communication.
Contactless near field data exchange and authentication via smartphone.
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. At the same time, an NFC device can work more or less like a reader and read cards and transponders itself. NFC also supports peer-to-peer communication (P2P) between two active devices. The major advantage of NFC is its extremely low energy consumption.
