Once you have established an E-ZPass prepaid account with one of the participating agencies, you will receive a small electronic transponder that attaches to the inside of the windshield of your vehicle.
When you travel thru a toll facility where E-ZPass is accepted, an antenna at the toll plaza will read your transponder and your account will be debited the appropriate amount for the toll.
Toll agencies participating in the E-ZPass program offer several choices for their customers to replenish funds in their accounts. The most convenient method of replenishment for customers is the auto replenishment feature, whereby your account is automatically replenished whenever your account balance is low, by charging a credit card you designate for that purpose. No credit card? No problem! Customers may replenish their accounts with cash as well.
