What is NFC? [Copy the Link]

What is NFC?

The clue is in the name: Near Field Communications. NFC is a set of standards for portable devices. It allows them to establish peer-to-peer radio communications, passing data from one device to another by touching them or putting them very close together. It's *communication* between *near* devices.
In essence, if your phone has NFC as a feature it can be used to transfer data to other phones or to NFC readers.

How does NFC work?
NFC is a means of sending data over radio waves. In that sense it is similar to Wi-Fi or Bluetooth, but unlike those protocols (and like RFID) NFC can be used to induce electric currents within passive components as well as just send data. And it is faster than Bluetooth, in general. Indeed the two are closely linked, Samsung Beam uses NFC to pair devices, and then Bluetooth to transfer data.

Uses of NFC
Well as mentioned earlier there are peer-to-peer technologies such as Android- or Samsung Beam, wherein you can share a file or a contact by touching together two smartphones. That's kind of cool.

Important: Not all cellphones have NFC.
