The Apple AirTag perfectly complements the “Find My” ecosystem in iPhones, iPads, MacBooks and more.

Users can also mark an AirTag as lost while providing a phone number and a message, both of which can be seen from iPhones with the “Identify found item” feature in the Find My app by tapping it near its NFC coil – same with Android phones.

AirTags are indeed tiny—about the smallest they can get, judging by the density. Speaking of density, the relative darkness of the AirTag is due to a hefty central speaker magnet and its steel battery cover—both fairly opaque to X-rays.
