For example, when a wallet is lost, Tile Slim can help find it. The device is just 2mm thick and can easily fit into any pocket. Battery life is up to 12 months. A smartphone app makes it easy to locate the item on which the device has been placed. When the gray button is pressed twice, the smartphone is activated and receives the call. Tile Slim runs over the network, so it can theoretically be used worldwide because it sends signals to any other device that has the Tile app installed.
