Near-field communication (NFC) is a short-range wireless connectivity technology that uses magnetic field induction to enable communication between devices when they're touched together or brought within a few centimeters of each other. This technology can be embedded in a small tag to facilitate data transfer between nearby mobile phones, laptops, tablets, and other electronics.
