Apple’s long-rumored AirTag has finally arrived to help Apple users find their car keys via the familiar Find My app. You can track down one of the little metal discs in your couch via Bluetooth and Ultra Wideband. Elsewhere in the world, you can find an AirTag using Apple’s vast Find My network, which leverages nearly a billion in-use Apple devices to relay a tag’s location across town or the globe.
In a move that has received little attention so far, Apple will let other makers’ products send privacy-protected “I’m lost” signals to Macs, iPhones, and iPads, as soon as year’s end.
Apple’s updated Find My service crowdsources the location of a missing device by letting other Apple equipment identify its unique Bluetooth signals and transmit them to Apple anonymously and securely.
