Near Field Communications or NFC is relatively new to our Windows Phones with the technology having enormous potential. With NFC Launchit, you can program NFC tags with a variety of actions to make life a little easier. All from your Windows Phone.
You'll need a supply of unprogrammed NFC tags and with NFC Launchit you can program two types of actions based on System Apps and Popular Apps. If you only use your Bluetooth when in your car, program a NFC Tag to launch your Bluetooth and stick it to your car visor.
