AirTag is a tracking device developed by Apple. [1] 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.[2] AirTags are compatible with any iPhone, iPad, or iPod Touch device capable of running iOS/iPadOS 14.5 or later, including iPhone 6S or later (including iPhone SE 1, 2 and 3). Using the built-in U1 chip on iPhone 11 or later (except iPhone SE models), users can more precisely locate items using ultra-wideband (UWB) technology. AirTag was announced on April 20, 2021,[3][4] made available for pre-order on April 23, and released on April 30.
