It finds lost items through Apple's Find My network, a crowdsourced network which consisted of approximately 1 billion devices in early 2021. AirTags are compatible with any iPhone, iPad, or iPod touch running iOS/iPadOS 14.5 or later. With the built-in U1 chip, users of iPhone 11 or later models (excluding iPhone SE 2nd generation) can use Ultra Wideband technology for Precision Finding. AirTag was announced on April 20, 2021, with pre-orders starting April 23 and official release on April 30. To prevent unwanted tracking, iOS/iPadOS devices alert users if an unknown AirTag is seen moving with them. AirTag requires an Apple ID and iOS or iPadOS 14.5 or later. It uses a CR2032 coin cell battery that lasts about a year and is user-replaceable. | A2187 | Height: 8mm Width: 31.9mm Weight: 11 g |
