AirTag

AirTag is an easy way to keep track of stuff. Attach it to your keys or slip it in your backpack to
see your items in the Find My app. If you misplace something, play a sound or just say "Hey
Siri, find my wallet" to locate the item you're looking for. Or if you've lost something farther
away, the hundreds of millions of iPhone, iPad, and Mac devices around the world that make up
the Find My network can help you find your lost item without compromising your privacy. Put
AirTag in Lost Mode and set a message telling the finder how to reach you.

Documentation
Precision Finding
If your AirTag is nearby, your iPhone can lead you to it with Precision Finding - which shows you the
distance and direction to head in, thanks to the Ultra Wideband technology built into AirTag and
iPhones 11 or newer.
Privacy
AirTag doesn't physically store your location data or history on the device, and the data is encrypted every step of the way.
No one, not even Apple, knows the location of your AirTag or the identity of any device in the Find My network that helps find it.
AirTag is designed to discourage unwanted tracking, so if an AirTag that isn't yours is travelling with you, you'll get an alert on your iPhone and after a while, AirTag will play a sound so you'll hear it even if you don't have an Apple device.
