Near-field communication (NFC) is a set of communication protocols that enable two electronic devices,
one of which is usually a portable device such as a smartphone, to establish communication by bringing
them within 4 cm (1.6 in) of each other.[1]

NFC devices are used in contactless payment systems, similar to those used in credit cards and
electronic ticket smartcards and allow mobile payment to replace or supplement these systems. This is
sometimes referred to as NFC/CTLS (Contactless) or CTLS NFC. NFC is used for social networking, for
sharing contacts, photos, videos or files.[2] NFC-enabled devices can act as electronic identity
documents and keycards.[3] NFC offers a low-speed connection with simple setup that can be used to
bootstrap more capable wireless connections.
