NFC Quick Settings is a really basic Android app with no GUI of it's own, that simply adds an NFC tile to the tiles available to the Quick Settings panel.

Just for the curious, the application implements a basic TileService, that overrides:
- onStartListening() to check the default NFC adapter's current status, and update the tile state accordingly; and
- onClick() to show the device's NFC Settings by starting the NFC Settings activity.
