Create your own NFC tags with smartphone apps

NFC stands for Near Field Communication. The technology is not only used for mobile payment such as Android Pay and Apple Pay or exchanging photos and contacts between two mobile devices, but you can make a set of tasks on your device and have it remembered by a piece of sticker called NFC tag. A tag is available online for less than a dollar. It contains a chip and doesn’t have a power source. When an NFC-support device, such as a smartphone is close (usually, a back of smartphone faces to a tag within an inch or so), a tag takes a small amount of power from smartphone and send back whatever information it stores.

NFC Tools Pro Edition

NFC Tools is a basic app for managing NFC tags. With the apps, various tasks can be written on tags such as changing smartphones settings, making a phone call, playing music, etc. You can add multiple tasks to a single tag so tags would be unique, creative and useful. For example, a NFC tag in my car goes like this;

  • Disable Wifi
  • Enable Bluetooth
  • Play Google Music
  • Brightness mode to Automatic
  • Launch Google Map

An order of tasks are sometimes important, and you can freely change it in the apps. The tag in my car executes ‘Launch Google Map’ last, and Google Maps remains open. So, I can see the traffic or type the destination right away. NFC Tools is free, but some useful tasks are available only in NFC Tools Pro Edition ($3.49, for Android only)

Some apps provide even more creative way of using NFC tags. Here are some apps.


When you invite your friend and let them use your Wi-Fi network, you have to tell them a password. However, InstaWifi allows you to let them connect to your Wi-Fi without giving up the password. After writing NFC tags, all you have to do is to tell your friends to tap the tag with their devices. The devices must support NFC technology, but InstaWifi has an option to create QR code instead of NFC tag. InstaWifi is free (for Android only.)

Sleep as Android

Sleep as Android is the app for tracking your sleep with smartphone’s sensors and setting the alarm with variety features. One of the features called CAPTCHA keeps you from oversleeping. After writing a tag and setting it up, you will have to tap the tag to stop the alarm. Stick a tag somewhere far from your bed, say bathroom. After stopping an alarm, just wash your face and your day will start without wasting any minutes. CAPTCHA has many other options like Simple math, QR Code, etc. And a sleep tracking data would be useful and helpful to improve your sleep. Sleep as Android costs $3.99, and it’s free to try for two weeks (for Android only.)
