AirTag makes it easy to keep track of your belongings. Just attach one to your keys, or put it in your backpack and you’re good to go. It has a built-in speaker and accelerometer sensor, and is resistant to water, dust, and a wide range of temperatures. It also has a user-replaceable CR2032 coin cell battery. If you misplace something, you can play a sound on the AirTag or use Siri to help you find it. Even if it’s far away, your iPhone can show you the distance and direction to it using the Ultra Wideband technology. Bluetooth is used to send out a secure signal and protect your privacy while the Find My network helps track it down. If your AirTag is lost, you can put it in Lost Mode and get a notification when it’s detected. Data stored on the AirTag is encrypted to protect your privacy. Setting up and connecting your AirTag to your iPhone or iPad is simple, and it can last for more than a year on one battery.
