There are many ways to flex your Android smartphone muscles to help make your mobile device not only easier to use, but practically automatic. One very useful tool is NFC Task Launcher, which allows you to purchase NFC tags, place them in specific locations, write commands to the tag (through the Android device), and then make magic happen.
With this handy app/tag combo, you can do things like:
- Turn on and off services based on location
- Fire up a music app when you place the phone in a dock in your car
- Set your phone for "sleep" mode when you scan a tag on your night stand
- Allow guests to automatically connect to Wi-Fi at your house by simply scanning the tag
- Enforce a phone silence policy for meetings by making all Android users scan the "meeting tag"
- Set up automated tethering
- Install plugins for SMS and phone calls
The system supports the following services:
- Turn Wi-Fi on or off
- Turn Bluetooth on or off
- Make Bluetooth discoverable
- Turn Airplane mode on or off
- Launch any installed application
- Configure a new Wi-Fi connection and connect
- Configure and enable portable hotspot
- Turn auto-sync on or off
- Turn auto-rotation on or off
- Turn notification light on or off
- Set display brightness and auto-brightness
- Launch any Tasker Task (for users of Tasker)
- Change ringtone
- Change notification tone
- Change ringer mode (normal/silent/vibrate)
- Change ringer volume
- Change media volume
- Change alarm volume
- Change notification volume
- Set vibration
- Set alarm (both a fixed time and as a timer)
- Check in with Google Latitude, Foursquare, Facebook, and Google Places
- Send a tweet on Twitter directly from the tag
- Start / stop media playback
- Turn GPS on or off (root required)
- Turn mobile data on or off (root required)
- Change display timeout
- Change auto-rotation
- Change notification light
Since the service is written to a tag, nothing has to be configured from the end user's perspective.
What you'll need:
- Android smartphone (Android 2.3.3 or higher required)
- NFC Tags ($13.50 for six tags)
- SMS Plugin for texts
- Call Plugin for phone calls

Let's walk through the creation of a Task Launcher tag that will automatically connect a device to a wireless access point. With this set up, the user won't even need to be told the SSID or the password. Here are the steps for this process:Step 1: Open NFC Task Launcher
This one is self explanatory. You'll find the launcher icon for the app either on your home screen or in your app drawer.Step 2: Enable NFC When you first run the application, if NFC isn't running on the phone, you'll be prompted to enable the service. Tap on the Settings button (Figure A) to navigate to the NFC settings. Figure A

Make sure to give the tag a unique name.Once you have a name, tap the Add actions button. Select Wireless & Networks, and from the options that appear, tap Wifi Connect, and then tap Next. In the new window (Figure D), enter the necessary information for the connection, and then tap OK. Figure D
Make sure to select the right Auth Type for the connection (WEP, WPA, WPA2).Finally, tap Save & Writer (upper right corner of the New Tag window). The resulting window (Figure E) will instruct you to hold the tag up against the back of the phone. Figure E
If you want to write more than one tag for this action, check the box for Write multiple tags.
You have the following options:
- Include tag name
- Write multiple tags
- Make tag read-only
Once you've written the tag, tap the Done button (top right corner), and you're ready to use the tag. Locate the tag in a convenient place so that when people need to use the tag (by placing the backs of their phone against said tag), they can easily access it.
NFC Task Launcher is an amazing tool to help automate certain tasks and make your life quite a bit easier. Give this tool a try, and see if you don't wind up with creative and/or convenient tags all over your working and personal environment.
