What is NFC? Everything you need to know

NFC stands for “Near Field Communication” and, as the name implies, it enables short-range communication between compatible devices. This requires at least one transmitting device, and another to receive the signal. A range of devices can use the NFC standard and can be considered either passive or active, depending on how the device works.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.

At its core, NFC works to identify us by our enabled cards and devices (and by extension, our bank accounts, and other personal info.)

 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.
