NFC stands for Near Field Communication. It enables two different devices to talk to one another without any direct contact. You probably have NFC technology in your mobile device – it’s what enables Apple Pay and Samsung Wallet. NFC is also embedded into bus shelters and enables interactive advertising.There have been some early adopter brands such as Pizza Hut, which has tried out NFC marketing with a stick-on tattoo. That clever little stunt allowed people to order pizza straight to their door simply by swiping a phone against their arm.
