Near Field Communication (NFC) is a technology that makes it possible for NFC-enabled smartphones, tablets and other devices to establish radio communication with unpowered NFC chips. It is embedded in anything from credit card terminals to posters – simply by touching them together or bringing them into close proximity.
The most commonly used NFC applications to date have been contactless credit cards, ticketing systems such as the Oyster card in London, and access cards for office buildings, libraries and universities. However, as adoption of the technology grows, endless marketing applications are being made possible by NFC too.
