Near Field Communication (NFC) is very useful for transferring data between 2 devices. It could be that you want to send pictures, clips, files, or make a payment, NFC simplifies that for you. But how does it work? Let’s discuss the vital things you have to know about using NFC below:

What Is NFC?
The name for the technology already hints at how it works. You have 2 NFC-capable devices, and they can communicate with each other as long as they are near each other. They have to be close to each other’s “fields.” Communication happens through radio frequencies.
For mobile, NFC is marketed as a data-sharing tool and payment method. NFC on Android phones also let the same phone read and/or write to programmable NFC tags.
Do You Have NFC?
NFC is accessible on most high-end smartphones out there but it cannot be found on mid-range and entry-level phones. A useful way to check if your device has NFC is to search for NFC printing, mostly found somewhere in the back of the phone. On specific Samsung devices, “Near Field Communication” will be seen on the battery pack. Although, this will only apply to more ancient smartphones because a lot of recent models have no removable back.
On some phones — especially Sony Xperia handsets — the N-Mark will be visible, which is the official symbol that shows the phone is NFC-enabled. The N-Mark also displays the precise location of the NFC chip.
You can also forget all of the hardware stuff and check your device’s Settings menu:

- On your Android phone, click “Settings.”
- Choose “Connected devices.”

- “NFC” or “Android Beam” options will be seen.
How Can I Activate NFC?
If your phone has NFC, the chip and Android Beam have to be enabled so you can use it. This is how to go about that:
- On your Android phone, click “Settings.”
- Choose “Connected devices.”
- Choose “Connection preferences.”
- “NFC” or “Android Beam” options will be seen.
- Activate both options.
Smartphones’ NFC capabilities work together with Android Beam. If the Android Beam is deactivated, it might restrict NFC’s sharing capacity.

How Can I Share Data Through NFC?
With NFC enabled, you already make use of it for beaming data. To successfully share data, do this:
- The two ending and receiving devices must have NFC and Android Beam enabled.
- None of the devices should be asleep or locked.
- You will receive both audio and haptic feedback when both devices detect each other.
- Make sure the devices are not separated until beaming begins.
- Audio feedback will be heard when the file or content has been successfully beamed.
