NFC Task Launcher:
NFC Task Launcher makes NFC useful for every day life.  You can use a single NFC tag to configure your phone or perform actions immediately when it is read.

You can do cool things such as:
- Turn on Bluetooth, turn off Wifi and Start up your favorite Music app when you place it in a dock or scan a tag in your car
- Set your ringer to vibrate, dim the display and set an alarm when you scan a tag on your night stand
- Start up Wifi and automatically connect to your home network when you come home (this also works great for guests so they never have to enter your wireless network info manually)

Because the commands are written to the tag there is no service to sign up for and they work on *any* device with the app installed.  Everyone who scans the tag will have the same actions performed.  The list of possible actions is shown below as well as any task you configure with Tasker.  Actions can be performed in any order and in any combination.  The only limit is what you can come up with!

NOTE: Licensing is done through the market.  If you are having licensing issues please contact us - it's usually a market issue.
