The Washington Metro Transit Authority sells a special card for frequent users of public transportation. Called SmarTrip, this card contains a special computer chip. This chip not only keeps track of the money in the SmarTrip account, but it also makes scanning magnetic strips a thing of the past. The SmarTrip card is merely tapped onto specific areas and the rider gains access to the bus, rail or subway. The SmarTrip card is a debit card, not credit. So a balance must be paid to keep the card current.
