NFC is a method to wirelessly share information on your Smart Phone™. Use NFC to share contacts, websites, and images. You can even make purchases at locations that have NFC support. An NFC message appears automatically when your phone is within an inch of the target device.

Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4cm or less to initiate a connection. NFC allows you to share small payloads of data between an NFC tag and an Android-powered device, or between two Android-powered devices.

How to enable NFC on Smart Phone?
1) Go to Settings > More.
2) Tap on the “NFC” switch to activate it. The Android Beam function will also automatically turn on.
3) If Android Beam does not automatically turn on, just tap it and select “Yes” to turn it on.

Is NFC better than Bluetooth?
NFC is limited to a distance of approximately four centimeters while Bluetooth can reach over thirty feet. While it may seem that Bluetooth is superior in this regard, both Bluetooth and NFC technology have their advantages and disadvantages compared to one another and can work together to meet users' needs.
