Apple AirTag two pieces

AirTag is designed to act as a key finder, which helps people find personal objects such as keys, bags, apparel, small electronic devices and vehicles

Apple AirTags are small discs—a bit over an inch in diameter—used for tracking an item's location. Place an AirTag in a handbag or suitcase, or attach it to a small item like keys, and you'll be able to keep tabs on where the item is by checking the Find My app on your iPhone or iPad..
