The AirTag is a small, disc-shaped accessory that used Apple’s Find My network to easily locate items. Apple described AirTag as “a supereasy way to keep track of your stuff. Attach one to your keys, slip another in your backpack. And just like that, they’re on your radar in the Find My app.”
The AirTag measures 1.26 inches (31.9 mm) diameter and is 0.31 inch (8.0 mm) high. It weighs 0.39 ounce (11 grams). It contains a CR2032 coin cell battery that can be replaced by the user. The AirTag uses wireless connectivity including Bluetooth, an Apple U1 chip (Ultra Wideband and Precision Finding), and NFC (Lost Mode). It is splash, water, and dust resistant (IP67 with a maximum depth of 1 meter up to 30 minutes).
The AirTag was offered with free engraving featuring a selection of 31 Apple-designed one-color emoji, text, or numbers. Up to 4 characters could be added. This example is engraved with my initials, “MJF.”
The Air Tag “requires iPhone SE, iPhone 6s or later, or iPod touch (7th generation) with iOS 14.5 or later, or iPad Pro, iPad (5th generation or later), iPad Air 2 or later, or iPad mini 4 or later with iPadOS 14.5 or later.”
