In what might be a compelling reason to go back to using your spare change when paying tolls on the highway, we found this report of E-Z Pass data being used to prove infidelity:

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.”

Whether it’s E-Z Pass or Fast-Lane, such devices provide an often overlooked source of evidence.
