NFC, or near-field communication, is an easy and intuitive technology that allows you to use your mobile phone for special purposes. An NFC tag can share and link to information such as web pages, social media and all other sorts of other information generally. Other areas where NFC is starting to evolve into are making payments, opening doors secured with contactless locks, logging on to computers and many more. All of these actions have something in common, that is they invoke an action based on you placing your phone (or any other NFC device) near (the N in NFC) the thing you want to read or interact with.

NFC is bridging the gap between both the physical and virtual worlds. By bringing two devices near each other, there is a virtual reaction. Bluetooth and WiFi do not have this ease in set up. So the key feature of NFC is: It is automatic! There is no need to launch an application! …it just works!™
In more technological terms, NFC defines the way two products communicate with each other. NFC is short range wireless RFID technology (1-4cm realistically, 10cm theoretically) which uses low speeds (106-414 kbps) and a low friction setup (no discovery and no pairing), which then allows two devices to automatically start communicating when they are close to one another.
