Apple AirTag

Design and Functionality

AirTags are made from stainless steel and have a water- and dust-resistant design. They feature a removable cover that allows users to change the CR2032 battery, which lasts about a year with regular use. Users can personalize their AirTags with free engravings on one side[2]. To set up an AirTag, users simply pull a plastic tag to activate the battery, then hold the device near their iPhone or iPad. The process is similar to pairing AirPods and typically takes less than 90 seconds[3].

Once set up, the AirTag appears in the Find My app, where users can name it and track its last known location. If within Bluetooth range, users can make the AirTag emit a sound to help locate it. Additionally, Siri can assist in finding lost items linked to an AirTag[2].

Privacy and Security Concerns

Apple emphasizes privacy in its design of AirTags. They do not store location data or history, and communications through the Find My app are end-to-end encrypted. However, concerns have arisen regarding potential misuse for stalking. In response, Apple has implemented features to alert users if an unknown AirTag is traveling with them. For example, if an AirTag not associated with a user’s Apple ID is detected nearby, an alert will be sent to their device[2][3]. The company has also introduced additional security measures, including improved warning sounds and a tracker detection app for Android users[2].

Limitations

While AirTags are effective for tracking personal items, they are not designed for real-time tracking of moving objects like vehicles. Their location updates occur when they come within range of other Apple devices in the Find My network[1][6]. Moreover, unlike some competing products like Tile, AirTags do not have built-in holes for easy attachment; users must purchase separate holders[3].

In summary, Apple AirTags offer a convenient way to keep track of personal belongings while prioritizing user privacy. However, potential security concerns related to their misuse highlight the need for ongoing vigilance among users.
