How Airtag Works
Airtag uses a feature called “Item Safety Alerts” to notify users if an unknown Airtag is traveling with them. This is designed to prevent unauthorized tracking or misuse of the tracking capabilities.
Steps to Receive Signal Alerts
1. Ensure your Airtag and device are updated with the latest software.
2. Enable the “Item Safety Alerts” feature in the Find My app settings on your device.
3. If another Airtag is detected moving with you, you will receive a notification on your device.
By following these steps and staying vigilant, Airtag can help protect your privacy and alert you to potential tracking by others.
