What is Android NFC? Everything You Need to Know

When it comes to wireless technologies, Android NFC (Near Field Communication) is very similar to Bluetooth and Wi-Fi. Here, data travels via the air using radio waves. Just as the acronym suggests, Android NFC is a wireless communication that takes place between an Android device and an NFC tag or between two Android devices.

This technology is simple to comprehend. It evolved from RFID (radio frequency identification) which is used in credit cards, shopping tags and microchips to store personal information. It is an electromagnetic energy that carries this information from the NFC tag for the sole purpose of being read.

If you want to share your files with a friend, you have to make sure that both your Android powered devices are at close range of approximately 4cm, otherwise you won’t get the results you’re looking for.

Once you are near a device that has an NFC tag, a message will appear automatically on your phone. This will show a tab where you will choose whether to accept or decline the interaction. An NFC tag can be a small sticker that is placed on a card and is powered with an NFC chip. They have been used for a variety of functions and make your mobile life simpler.
