Update December 13: This change did not make it into the final release of iOS 15.2, but may reappear in a future update.
In iOS 15.2, which is available in beta right now, Apple introduced new features for the Find My app, including a way to search for items that might be used to track your location.
The new Unknown Items feature is called "Items That Can Track Me," and when activated, it will scan for anything that's nearby that belongs to someone else and let you know about it.
If anything is detected, such as an AirTag or other Find My-enabled item, Apple will provide you with more details on the item and instructions on how to disable it so that it can no longer be used for tracking purposes.
The following steps show you how to activate the feature in iOS 15.2. Note that items can only be found if they are not in range of their owner's device, up to 50 meters.
AirTags and items with Find My integration are meant to allow users to track their lost devices, but there have been concerns that AirTags can be planted on people for stalking purposes. To prevent stalking with AirTags and other devices, Apple has implemented several safety measures.
AirTags are designed to start playing a sound between eight and 24 hours after being separated from their owner, and iPhone users are alerted if an AirTag is traveling with them. Apple is also working on an Android app that will let Android users detect an unknown AirTag or Find My network-enabled item to prevent AirTags from being used to stalk Android users.
