What is Near Field Communication (NFC)?

Near Field Communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together, or bringing them in close proximity with each other, usually no more than a few inches/centimeters.

NFC fits the criteria for being considered a personal area network, since it utilizes Bluetooth technology and can be used to communicate between devices within very close proximity to each other.

Some common uses for NFC include:

1. Tap to connect NFC enabled peripherals with no pairing or wireless connection set up needed (keyboards, mice, headphones)
2. Tap to play an NFC enabled game between friends
3. Tap to share – Share photos, url or documents
4. Tap to receive information from an embedded tag on a poster, etc.
5. Content is updated with your location automatically wherever you are (weather, restaurants, etc.)

Dell systems that incorporate NFC will include this symbol:
