AirTag(1st generation)
Lose your knack for losing things.
Background
AirTag is designed to act as a key finder, which helps people find personal objects (e.g. keys, bags, apparel, small electronic devices, vehicles). To locate lost items, AirTags use Apple's crowdsourced Find My network, estimated in early 2021 to consist of approximately one billion devices worldwide that detect and anonymously report emitted Bluetooth signals. AirTags are compatible with any iPhone, iPad, or iPod Touch device capable of running iOS/iPadOS 14.5 or later. Using the built-in U1 chip on iPhone 11 or later (excluding iPhone SE 2nd generation), users can more precisely locate items using UWB (ultra-wideband) technology. AirTag was announced on April 20, 2021, made available for pre-order on April 23, and released on April 30. To help discourage unwanted tracking, an iOS/iPadOS device will alert their owner if someone else's AirTag seems to be with them, instead of with the AirTag's owner. After a while, it will also beep to alert them that an AirTag may have been placed in their possession. AirTag requires an Apple ID and iOS or iPadOS 14.5 or later. It uses the CR2032 button cell replaceable with one year of battery life.
