AirTag uses a 'find' network built on iPhones around the world to send location information to its owners, rather than GPS. AirTag and surrounding iPhones are connected by Bluetooth, but AirTag's Bluetooth identifier is changed to a random value many times a day. In addition, communication on the 'find' network is

end-to-end encrypted, making it impossible for anyone other than the owner to see AirTag's location and owner information.
