New York City Subway [SEP] MetroCard
In November 1993, a fare system called the MetroCard was introduced, which allows riders to use magnetic stripe cards that store the value equal to the amount paid to a subway station booth clerk or vending machine. The MetroCard was enhanced in 1997 to allow passengers to make free transfers between subways and buses within two hours; several MetroCard-only transfers between subway stations were added in 2001. With the addition of unlimited-ride MetroCards in 1998, the New York City Transit system was the last major transit system in the United States with the exception of BART in San Francisco to introduce passes for unlimited bus and rapid transit travel.
