Tracking your lost luggage for finding house keys you’ve misplaced is made a lot easier with Bluetooth trackers.

In these cases, what Tile and Apple do is leverage everyone else’s Bluetooth connection to geo-locate a tracker marked as missing. In both cases as you walk by (within Bluetooth range) a tracker marked as missing, your phone sends back an anonymous, encrypted location of that tracker back to Tile or Apple. Tile says they’ve got 26 million users (potential people running their app who might happen to walk near a lost tracker).
