Tile is a new product which wants to revolutionise the way we lose and find things. A tile can stick or be attached to nearly anything and it communicates with your smartphone. When you lose something you can use your smartphone to locate it.
Tile doesn't just stop there though, with it being a cloud based system, it can help you find things which are way out of reach. If you were to lose an item which out of your smartphones reach, but another Tile user were to be in the area, their phone would communicate with the cloud, which will then tell you where your item is.
It seems like a big idea which I feel like may still be a bit ahead of its time, but you never know, this may be the thing which makes this idea real.
