A US technology firm has come up with Bluetooth stickers, which can be attached to your essential items like wallets and keys, and to track them.
Your valuables can be detected by the stickers, which work through a smartphone app that sets off a buzzer to help locate them.

The app also includes a radar-like function to help you find your way to your possessions. About the size of a coin, the stickers send a low-energy Bluetooth signal with a range of about 100ft.
