SignalTrace “links devices that regularly travel together, correlating them to license plate.” It is a surveillance product that will sweep up and add all sorts of Bluetooth and other data to license plate readers, linking specific devices—and people—to cars.
Could be overkill, but if you’re out and about your cell data is likely on. Then what? Now, my phone, my laptop, or other devices can utilize it. Unlimited data.
How’s that different from just running the hotspot on your phone?
