Just attach a Tile to items like your keys or stick one in your wallet or hide it in your car. Then, use your phone to track down your items using WiFi.
Instead of turning your house upside down when looking for your keys, Tile can sound off an alert so you can find them. You can see the last place you put things, and if your item is stolen, other Tile users unknowingly help the company track the item when it comes into close proximity with them. The more users, the better this concept works! Learn more and preorder your Tile now for just $18.95: http://www.thetileapp.com/
