Simply, it's a method of wireless data transfer that detects and then enables technology in close proximity to communicate without the need for an internet connection. It's easy, fast and works automatically.
How does NFC work?
The tech involved is deceptively simple. Evolved from radio frequency identification (RFID) tech, an NFC chip operates as one part of a wireless link. Once it's activated by another chip, small amounts of data between the two devices can be transferred when held a few centimeters from each other.
No pairing code is necessary to link up and because it uses chips that run on very low amounts of power (or passively, using even less), it's much more power-efficient than other wireless communication types.
How can I use NFC right now?
NFC chips stocked inside credit cards for contactless payments is nothing new. But a more recent and admittedly more enticing use case for NFC is with your smartphone, which can digitize your entire wallet.
