Bluetooth location trackers such as AirTags, Tile, and Samsung SmartTags are marketed as a way to keep track of luggage or a misplaced wallet, but they can also be easily slipped surreptitiously into a bag or car, allowing stalkers and abusers unprecedented access to a person’s location without their knowledge. These devices are small enough to fit inside wallets or on a keychain, which makes them difficult to find, especially if you don't know what you're looking for.
