To search and find objects ranging from a bag to a bicycle or a set of keys, all that is needed is a small tag, called an AirTag, which can be attached to the respective object.
Tracking is done via a phone with the “Search” app installed. AirTags are small (3 centimeters in diameter), thin (0.8 centimeters), light (11 grams). They are also durable, since the battery lasts more than a year, and they are also protected against water and dust.
To prevent it from being used for unwanted harassment or tracking, iPhone users receive a warning on the device screen if the device detects an AirTag stranger in the vicinity.
To protect Android users, AirTags are set to emit an audible warning signal when near someone who isn’t wearing an iPhone. However, the AirTag’s tiny speaker can easily be disabled for malicious purposes.
Probably as a result of this, Apple has a scanning app for AirTag called Tracker Detect, designed to protect Android device users from tracking and harassment attempts.
If Tracker Detect finds an unknown, alien AirTag in the vicinity, it can be commanded through the app to make a sound to help locate it. The app also contains instructions on how to disable third-party AirTags.
Additionally, Apple explains in Tracker Detect how to read an AirTag’s serial number and any loss information stored by the owner. To do this, the accessory uses NFC technology.
