The Tile GPS Tracker

The Tile, GPS Trackers for Bikes

Meet The Tile, little signal trackers that sync through an app so you can always found what you lost. This could be as small as finding your keys after a rough night, or maybe finding a stolen bike.

It seems from the video, the Tile communicates with iPhone/iPad (i-things) that have the Tile app downloaded. The idea is if everyone has the Tile app on their phone running the faster your lost item will be found.
