Leonardo, a company that provides license plate reader systems to law enforcement, has developed a system called SignalTrace (formerly EOC Plus, patented on March 26, 2024). This system uses sensors to collect signals from phones, smartwatches, Bluetooth and Wi-Fi devices, RFID tags in employee badges and pet microchips, toll pass transponders, etc, and then groups those signals into a unique "electronic fingerprint" that can be associated with a vehicle. This "fingerprint" allows law enforcement to recognize a vehicle without needing its license plate.
