If your AirTag is nearby, the Precise Location feature on your iPhone can guide you to its exact location. Thanks to Ultra Wideband technology you will see the direction to follow and the exact distance.
If you left something in a distant place, for example at the park or at the gym, you can still locate your AirTag using the Find My network: it is made up of hundreds of millions of iPhones, iPads and Macs around the world, and it is a system designed to keep your privacy safe at all times.
How does it work?
Your AirTag sends a secure Bluetooth signal that can be picked up by nearby Find My network devices. These devices send the AirTag's location to iCloud—when you open the Find My app, you'll see it on the map. The entire operation takes place anonymously and encrypted, to protect your privacy. And it's super efficient, too, so you don't have to worry about running out of battery or data.
Lost Mode: All is not lost.
Just like on other Apple devices, you can also activate Lost mode on AirTag. This way, if your AirTag is detected by a device on the network, you receive a notification automatically. You can also choose to show your contact information when someone touches your AirTag with a smartphone equipped with NFC technology (the same one used to pay with your phone).
