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.
