What is NFC (near field communication)?

hello guys in this post we are gonna talk about the NFC so lets get into our topic.

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.

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/supplement these systems. NFC is used for social networking, for sharing contacts, photos, videos or files. NFC-enabled devices can act as electronic identity documents and keycards.NFC offers a low-speed connection with simple setup that can be used to bootstrap more capable wireless connections.
