These are questions that many consumers will have as they hear more and more about this technology — and here are some answers. What is NFC, in a nutshell?

 NFC, which stands for near-field communication, is a type of communication that involves wirelessly transmitting data from one hardware device to another physical object, provided that the devices are in short range (within 10 centimeters) of one another.

 In order for NFC to work, both devices — say, for example, your smartphone and a payment terminal at your local CVS — have to have NFC chips and antennas embedded in them.

Over the past few years, NFC has become more prominent, but it’s still a long way from mass adoption.
