SmarTrip is a plastic contact-less stored-value smart card used for payment within the Washington Metropolitan Area Transit Authority (WMATA) system in Washington, D.C. Unlike traditional paper farecards, SmarTrip is designed to be permanent and reloadable, and it can be used in all Metrorail stations, all Metrobuses, and nearly all other local public transit systems in the Washington Metropolitan Area. SmarTrip is the primary way to pay for parking fees at Metro-operated lots.
