A problem with a simple solution

Stay faithful to your wife.

E-ZPass and other electronic toll collection systems are emerging as a powerful means of proving infidelity. That's because when your spouse doesn't know where you've been, E-ZPass does.

"E-ZPass is an E-ZPass to go directly to divorce court, because it's an easy way to show you took the off-ramp to adultery," said Jacalyn Barnett, a New York divorce lawyer who has used E-ZPass records a few times.

Lynne Gold-Bikin, a Pennsylvania divorce lawyer, said E-ZPass helped prove a client's husband was being unfaithful: "He claimed he was in a business meeting in Pennsylvania. And I had records to show he went to New Jersey that night."

Generally mounted inside a vehicle's windshield behind the rearview mirror, E-ZPass devices communicate with antennas at toll plazas, automatically deducting money from the motorist's prepaid account.
