Apple launched AirTag at its event on April 20, 2021. AirTag is the one Apple product that you never really want to use. The two practical use cases I came up with are tracking my wallet and keys. I decided that losing either would make me wish I had AirTag attached to them. But by then it would be too late!
AirTag uses Ultra-Wideband technology to guide you straight to the tagged object by displaying both distance and direction on your iPhone.
Find My Network
AirTag uses the Find My network to leverage over 1 billion Apple users to help find your lost item. The AirTag works by sending out a Bluetooth signal that can be picked up by nearby devices in the Find My network. These devices then send the location of your missing AirTag to the iCloud, which you can see on the map in the Find My app.
If you accidentally leave behind your item, you can be alerted by a notification on your phone. This option is customizable by location to have exceptions.
If you do lose an item, you can activate Lost Mode. When the AirTag is detected by another Apple device, you will receive a notification. It is also possible to set it such that the person who finds the AirTag can receive your contact information by tapping it with an NFC-equipped smartphone.
