Electronic Toll Systems Increasingly Used in Civil, Criminal Cases
I-Pass, which is part of the E-ZPass system, and other electronic toll collection systems around the country are emerging as a powerful means of proving infidelity. That's because when your spouse doesn't know where you've been, the pass does. Records that show which tolls an I-Pass user traveled through can be used against the driver in divorce court or criminal cases. The devices communicate with antennas at toll plazas, and money is automatically deducted from the motorist's prepaid account.
