The CharlieCard is a contactless smart card used for fare payment for transportation in the Boston area. It is the primary payment method for the Massachusetts Bay Transportation Authority (MBTA) and several regional public transport systems in the U.S. state of Massachusetts. In 2022, the original CharlieCard system will be replaced during the "Automated Fare Collection 2.0" project, a system similar to the London Oyster Card. The new system will allow payments with contactless cards and smartphones, as well as new CharlieCards.
