Apple’s AirTag is a button-sized device that can be attached to things to keep track of them. They use Bluetooth and Near-field communication (NFC) to anonymously communicate with a nearby iPhone through Apple’s “Find My” feature. In doing so, they can be used to actively monitor the device’s real-time location. Although equipped with security safeguards, AirTags can easily be abused for malicious intent. If you find one in your belongings or attached to your car, remove the device and discard it immediately.
