You’ve probably encountered the abbreviation NFC while using your smartphone. In this article, we’ll explain what NFC in Smartphones is and how to use this handy feature on Android devices.
What Is NFC?
NFC stands for Near Field Communication, a modern wireless communication technology that allows devices to exchange information over high radio frequencies at short distances (about 10 centimeters). Unlike Bluetooth, NFC does not require physical contact between devices.
Initially, NFC was primarily used for contactless payments in retail and public transportation. Today, it is widely integrated into mobile devices, expanding its functionality.
Most smartphone manufacturers now include NFC modules in their devices. Thanks to NFC, we can connect our smartphones to various electronic systems, such as using them as payment tools by installing specialized apps. The technology also ensures a high level of data protection.
This means that smartphones today can serve not only as communication devices but also for transmitting and receiving information, paying for purchases, or buying transport tickets. They can act as virtual payment cards or even access passes for workplaces or facilities.
Additionally, NFC is convenient for using NFC tags and smart cards, as well as for quickly sharing data.
How to Use NFC on Android for Data Transfer
The Android operating system introduced NFC support alongside a built-in feature called Beam. However, not all devices are equipped with NFC adapters. To check if your device supports NFC, look for the abbreviation on the device itself or its battery. Alternatively, navigate to the Wireless Networks section in the settings menu and select More.
If you see an NFC option, it indicates the presence of an NFC adapter.
Activating NFC:
- Enable the option to allow data exchange when your phone is brought close to other devices.
- If the Beam feature does not activate automatically, you can enable it manually.
Sharing Data with NFC:
Once NFC and Beam are activated on both devices:
- Ensure neither device is locked or in Sleep Mode.
- Open the content you want to share (e.g., a YouTube video, photo, or web page).
- Place the back panels of the devices close to each other.
- Wait for the devices to detect each other and prompt for data sharing.
- Tap the screen to confirm and start the transfer.
You’ll hear an audio signal at both the beginning and end of the data transfer.
