E-ZPass

E‑ZPass is an electronic toll-collection system used on most tolled roads, bridges, and tunnels in the midwestern and northeastern United States, south to North Carolina, and west to Illinois. Currently, there are 37 agencies spread across 16 states that make up the E‑ZPass Interagency Group (IAG). All member agencies use the same technology, allowing travelers to use the same E‑ZPass transponder throughout the IAG network. Various independent systems that use the same technology have been integrated into the E‑ZPass system. These include I‑Pass in Illinois and NC Quick Pass in North Carolina. Other interoperable systems retained their own branding for some time, but have all since been rebranded simply as E-ZPass.
