  In general:

  • The tracker sends out low-energy Bluetooth announcements including its unique id
  • a nearby iPhone hears those announcements
  • the iPhone uses its current location
  • the iPhone sends the tracker id and the location back to Apple via WiFi or cell
  • Apple notifies the owner of the tracker where the tracker was seen
