Bluetooth trackers have been around for a long time, and they all generally work the same way. You stick the tracker onto an object, pair it with your phone, and then, when you lose said object, you can go into an app and ring the tracker. But these days, Bluetooth trackers can do a lot more. Some have ultra-wideband chips that enable precision tracking, so you can find exactly where in a room your item is. Increasingly, trackers also tap into large networks — like Apple’s and Google’s — making it easier to locate lost items outside the home. Many will notify you if they detect you’ve left the device behind or come with QR codes that link to your contact information so people can easily return lost devices.
