Company Will Add Phone, AirPod, and Smartwatch Trackers to ALPRs

A surveillance company is developing SignalTrace, technology that would add sensors to automatic license plate readers (ALPRs) to capture Bluetooth identifiers from phones, AirPods, and smartwatches in passing vehicles. This capability would transform ALPRs from vehicle-tracking devices into people-tracking tools, potentially allowing law enforcement to identify specific drivers and passengers based on their personal devices.
