But the question is do you know how to use NFC on Android devices?
How to use NFC on Android devices
You can share pictures, music, and videos wirelessly with your Bluetooth and Wi-Fi directly. Sometimes it works, other times it doesn’t. Another technology near field communication or NFC lets you share stuff too. Just by tapping your devices back against the back of another NFC capable device.
How do you share stuff via NFC?
In this post, I’ll show you how to use NFC to share data and files anti program NFC tags.
In the time of testing, I was using android devices all of which have NFC. The steps I mention here may or may not work for your device. So, you need to have NFC capabilities.
How do you check your device for it?
One way to check it is by looking at your devices Backplate. Some devices have an NFC certification sticker on the back plate, and some device has the NFC logo. Another way is to go to the settings menu under wireless and networks. Tap on more you should see NFC and android beam among the other options once you’ve confirmed that your phone or tablet does have NFC.
You also need to activate the NFC chip to be able to share data through it. Just tap the NFC option on the menu android beam will also automatically activate. Both options need to be on, otherwise, you will be unable to use NFC properly.
Both the NFC chip and android beam allow you to swap data between two capable devices just by tapping their bags together. Through NFC, you can share certain types of data such as photos, contact information, website URLs, videos and apps. You only need to beam the data to the recipient device. To successfully beam data both NFC and android beam should be active on the sender and receiver devices.
Next, select the content that you want to share. Ideally, the receiving phone should be on its home screen. Put the devices back together. On the sender phone, you’ll see the display shrunk into a thumbnail and the words touch to beam shown at the top. Tap the thumbnail to beam it. When beaming is successful, you will receive a notification or an app will launch on the receiving phone.
This is the typical procedure when beaming files and content. You’ll notice this procedure used repeatedly in this guide.
Let’s try it out by sharing an image via NFC
Now that you have an idea of the general way of being content via NFC. Let’s try it out by sharing an image. Sharing a photo or image via NFC is extremely easy. First, open the image. This is usually done in the gallery app. Then place the back of your device against the back of the recipient device like this both devices will make a sound and vibrate slightly indicating that the devices have made contact. On the sender device, you’ll see a thumbnail of the image window and the words touch to beam on top.
Your image file is now ready for beaming. Tap on the screen to beam it. Don’t separate the devices until you’ve tapped to be the receiving device well get a notification that says incoming beam no need to do anything here. Just wait for it to complete. Once beaming is complete you can access the image by pulling down the notification shade and tapping on beam complete or by going to the gallery app.
Sharing an App via NFC
Through NFC you can also share apps. Not the actual app files themselves. Just the apps page on the google play store. To share an app just launch the app then place both sender and recipient devices back-to-back until you feel the familiar vibration and hear the familiar NFC sound.
Sharing a web page via NFC
You can also share an open web page easily with other devices. You can do it right from your browser window. Make sure that both devices are connected to the internet. You can share both Youtube videos and local videos too.
Sharing a Youtube video via NFC
Sharing a Youtube video is similar to webpage sharing. Just open the video in the Youtube app. Tap device backs like this touch to beam and there it goes. Both devices need to be connected to the internet of course.
Beaming a local video file is done in a similar way. Just open the video file usually in the gallery app tap both devices. Touch to the beam, wonderful.
Sharing Contact information via NFC
Contact information is also one of the most frequently shared content type. You can beam contact info through NFC too. It’s super easy. Open the contact info page. Tab the devices backs like this tap the screen to beam the contact card.
How to use locational NFC tags or stickers
Aside from beaming small chunks of data to another device NFC introduces another world of convenience through locational NFC tags or stickers. Such tags or stickers contain microchips that store information readable by NFC capable devices. Just tap your NFC device on a tag and it will read the instructions on that tag. Tags can contain website URLs, contact information, and even device setting profiles that can be activated on a device.
So you can stick to such tags in various places. For example, stick a tag to your office desk and tap on it to activate your devices office profile settings or stick a tag to a poster and tap your device on it to quickly open a website. To read data from or write data to such NFC Tags you’ll need an NFC Tag reading or tag writing app.
The Optimus G for instance comes pre-loaded with such an app known as the LG Tag plus app. Tags programmed using this app can only be read by devices that have this same app installed.
How I use NFC on Android
I have several NFC tags and they are programmable tags that came with my Optimus G. I can program an NFC tag to open a web page, configure my phone settings, or even send a text just by tapping my phone against the tag. So, for instance, I want this NFC tag to set my phone to vibrate mode, turn on Wi-Fi and turn off Bluetooth. This configuration is perfect for office use. So I can just stick this tag to a corner of my desk and tap my phone on it upon arriving.
