EZPass

EZ-Pass is an electronic toll collection system used on many toll facilities in the United States. It is operated by the E-ZPass Group, a cooperative of state and regional toll agencies that coordinates interoperability among participating agencies. The system relies on RFID transponders (tags) mounted on vehicles and prepaid accounts. As vehicles pass readers at toll plazas or gantries, tolls are automatically deducted from the account, enabling cashless and often faster crossings.

History and scope: The concept emerged in the 1980s and was first implemented on major Northeast toll roads in the early 1990s. The E-ZPass Interagency Group (IAG) was formed to standardize technology and expand interoperability across agencies. Since then, the network has grown to include multiple states in the Northeast, Mid-Atlantic, and parts of the Midwest, with many facilities accepting a single tag across participating jurisdictions.

How it works: Users obtain an EZ-Pass transponder and link it to an account funded by prepaid value or linked payment methods. The tag is read when passing under toll sensors, and the corresponding toll is charged to the account. Some agencies also support license-plate tolling for vehicles without a transponder, billed to the registered owner by mail, typically at higher rates. The system emphasizes convenience, reduced queuing, and consistent pricing across many toll facilities.

Privacy and availability: Toll agencies limit data use to toll administration and enforcement within applicable laws. EZ-Pass is widely available across participating states, with ongoing efforts to maintain interoperability and expand coverage where possible.
