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.
What does NFC do on my phone?
Near Field Communication (NFC) is a method to wirelessly share information on your Samsung Galaxy Mega™. 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.
Do I need NFC turned on?
Apart from security concerns, NFC can also be using some of your battery juice. On some devices, Near Field Communication is enabled by default and therefore you should disable it. I don’t, in any sense mean, that NFC should not be used. If you rarely use NFC, then it’s a good idea to turn it OFF.
How do you use NFC on Android?
If your device has NFC, the chip and Android Beam need to be activated so that you can use NFC:
- Go to Settings > More.
- Tap on the “NFC” switch to activate it. The Android Beam function will also automatically turn on.
- If Android Beam does not automatically turn on, just tap it and select “Yes” to turn it on.
What is the NFC setting on Android?
Near Field Communication (NFC) allows the transfer of data between devices that are a few centimeters apart, typically back-to-back. NFC must be turned on for NFC-based apps (e.g., Android Beam) to function correctly. From a Home screen, navigate: Apps icon > Settings .
