Apple AirTag — smart tags from Apple, The device itself is a "tablet" with a diameter of 30 mm. Its cover is made of stainless steel, it has the Apple logo on it, as well as information about the device. AirTag works from a regular CR2032 watch battery. In a new device, it is already inserted, and so that it does not discharge before it reaches the buyer, a thin but durable transparent film is inserted between the battery and the contacts on the white base, similar to those that protect the screen and back of the new iPhone. We simply pull the protruding tab - and the film is completely pulled out, and the battery touches the contacts, and AirTag makes a melodic sound, announcing its readiness to work.
