Ever came across the acronym NFC? If you’re working in the tech field or you’re a gadget enthusiast, you probably have an idea what NFC or Near Field Communication is all about. Otherwise, it might just make you scratch your head.

NFC and Payment

NFC, or Near Field Communication, is a technology designed to make transferring data easier between two devices. Whether it’s a photo or video you want to send, or you wish to complete a payment, NFC can make it possible. But how does it work? Can you even use it on your Android device?

How NFC Works on Android

NFC is currently being marketed as a data and file-sharing technology. It became popular in the mobile scene after Google released Android Ice Cream Sandwich, which introduced the Android Beam functionality.

When used together with Android Beam, NFC lets devices exchange files easily. Furthermore, the use of NFC on Android devices enables reading and writing programmable NFC tags that serve as a storage space for a wide range of data, including web addresses, app links, and contact details.

As long as NFC-capable devices are close to each other, they can communicate with each other. The communication takes place with the help of radio frequencies. The rest is science.

Is Your Device NFC-Capable?

Unfortunately, not all devices have NFC. To check if yours supports NFC, check the backplate of your device and look for any clues. For instance, Samsung phones have the words Near Field Communication printed on the battery pack. On other devices, such as Sony Xperia smartphone models, you will see the official symbol of NFC-enabled devices, N-Mark. You can also manually check your device’s settings to verify if it is NFC-enabled. Follow the steps below:

  • Go to Settings > More Settings.
  • Scroll down until you see the NFC and Android Beam settings.

How to Activate NFC on Your Device

Confirm that your device has NFC, activate Android Beam and the chip so you can start using NFC. Here’s how you do it:

  • Go to Settings -> More Settings.
  • Toggle the NFC switch to enable it. As you do that, the Android Beam function will turn on as well.
  • If Android Beam does not activate, tap it and then press Yes to switch it on. Technically speaking, you can only maximize what you can do with NFC on your Android device if Android Beam is also enabled.

How to Share Data via NFC

Once you have successfully activated NFC on your device, you are all set for sharing data with other devices. To ensure you succeed with data sharing, be reminded of the following:

  • Both the receiving and sending devices should have Android Beam, and NFC enabled.
  • Both devices should stay unlocked.
  • There will be audio feedback whenever two NFC-enabled devices detect each other.
  • While sharing data with another device, make sure you don’t separate them.
  • There will also be audio feedback to notify you when data sharing is successful.

Here is the generic way to share data via NFC:

  • Open the file you want to share.
  • Position both devices with their backs against each other.
  • Wait until you hear audio feedback to confirm that both devices have detected one another.
  • The screen of the sending device will shrink into a thumbnail. It will also display the message, “Touch to Beam.”
  • Tap it to start beaming. There will be another audio feedback once sharing starts.
  • Finally, when sharing is completed, you will hear another audio feedback.

Wrapping Up

A lot of Android devices on the market today already support NFC functionality. So, if you carefully read this guide, you should be able to share files and data using this breakthrough technology.
