We are still waiting to see if Apple officially unveils a new spin on the business of tracking tags — the small devices that you put on ‘dumb’ objects like keys, wallets and other objects you have a habit of losing or leaving places to be able to pinpoint their location — but in the meantime, Tile, one of the pioneers of this technology, is upping its game today with its least-obtrusive device yet: a sticker.

Today, the startup unveiled Sticker, a new, waterproof tracking device that it created in collaboration with 3M, which uses adhesive to attach to objects to be able to track them by Bluetooth to a range of 150 feet, or further using Tile’s community network by way of its app.
