Customers no longer need to fumble for pocket change when riding Maryland Transit Authority buses and light rail. The CharmCard streamlines the ticketing process for riders by introducing an electronic payment system.

Riders can load money onto their CharmCards using cash or a credit card. The card then simply has to be touched to a card reader that allows customers to board MTA buses or Metro and light rail trains. The system deducts the fare from the card. The new CharmCard makes getting around on public transportation easier for Maryland riders. Instead of a pocketful of change, riders have just one card to keep track of. The card can hold up to $200 in value.
One major advantage that comes with the CharmCard is versatility. The card is interchangeable with the Washington D.C. SmartCard. Riders can use one card for both transportation systems.
