NFC what it is and how it is used on Android devices

NFCwhat (Near Field Communication)? You've heard of it but you don't know what it is, and here we also want to explain its use on Android devices. NFC how it works and what is it for? It is an interesting and useful feature for smartphones, introduced only a few years ago. This function allows the transmission of data (photos, videos, documents, web pages, app links, contacts, …) between two devices provided that both devices have NFC enabled. Although this feature has been in development for many years, now NFC has affected the Android market since 2012.

The reason that makes NFC more reliable than Bluetooth and WiFi is the faster transfer of information and data. As the full name says, NFC can only work when two compatible devices are close enough. It means that the NFC function has a transmission port shortly compared to Bluetooth and WiFi. Furthermore, it is important to know that there can be two types of NFC devices: active devices and passive devices.

Passive NFC devices are generally small tags and other transmitters.The purpose of these tags is to send information to the NFC device (which must be active) and act only as a source. An example of passive device can be a tag that sends the command to the smartphone to turn on or turn off the WiFi. These tags require no power source and can be easily customized to work with any NFC compatible device. Some good Android apps for tag customization are Triggering NFC Tools. note that passive devices cannot communicate with each other.

Active NFC devices are those that have more features. These devices are able to send and receive data (peer-to-peer connection). Active devices can communicate with each other. This feature has led to the creation and development of Android Pay, and some examples of NFC devices active with smartphones, card readers for public transport or touch terminals for payment.

Requirements for using Android NFC

  • An Android device with a built-in NFC
  • Another Android device (which has embedded NFC) to transfer data with the previous device.

Note: Instead of another device, a passive NFC device (tag) can also be used. In this guide, you'll see how to use NFC with both types of devices.

NFC what and how it works with active NFC devices

  1. Go to your smartphoneSettings Other.
  2. Click on the NFC option to activate it (Android Beam is activated automatically).

3. Repeat steps 1 and 2 with both devices to activate NFC.4. Make sure you are on the main screen of the smartphone that is to receive the files.5. Then, open the content you want to share on the sending device.6. After that, bring both devices close together.

7. A new screen will appear on the sender at the top of the screen. This means that the NFC device has been recognized.8. Touch the thumbnail on the sending device and the file will be sent to the receiver.9. A notification will appear on the display.10. Now, you can access the file on the other device.

This all. As you can see, using very simple NFC. It can work with all active devices, including Android terminals for payment. Just simply bring the phone close enough, touch the display and the money will be transferred.

NFC as a function of passive devices

Note: In this section of the guide, how to use an active NFC device (smartphone) with a passive device (tag). You can use any passive device. For an easy understanding let's say that this tag turns on WiFi when a smartphone is approached.

Current status – WiFi Off (Before touching the tag).

  • Pass to Settings Other.
  • Click on the NFC option to activate it (Android Beam is activated automatically).
  • Touch the device with the tag.
  • A successful transfer notification will be displayed.
  • Current status – WiFi ON (after touching the tag).

I know it was easier to do than to say. Try this new feature and if you encounter any problems with NFC we will try to help you.

NFC a good feature. better than Bluetooth and WiFi for data transmission. Using NFC for payments is also safe and offers a great experience in everyday life, making payments and file transfers easier.
