what is air tag

AirTag is a tracking device developed by Apple that helps people find personal objects such as keys, bags, apparel, small electronic devices, and vehicles. AirTags use Apples crowdsourced Find My network, which consists of approximately one billion devices worldwide that detect and anonymously report emitted Bluetooth signals, to locate lost items. AirTags can be interacted with using the Find My app, and users may trigger the AirTag to play a sound from the app. iPhones equipped with the U1 chip can use "Precision Tracking" to provide direction to and precise distance from an AirTag. AirTags do not have holes or other mechanical features that would allow them to be positively attached or affixed to the item being tracked; solutions include adhesives (glue, tape) and purpose-built accessories. The polyurethane AirTag Loop is the least expensive solution sold by Apple. AirTag is designed to discourage unwanted tracking, and if someone elses AirTag finds its way into your stuff, your iPhone will notice its traveling with you and send you an alert. If you find an AirTag after hearing it make a sound, you can use any device that has NFC, such as an iPhone or Android phone, to see if its owner marked it as lost and if you can help return it.
