The MetroCard is the current payment method for the New York City Subway (rapid transit) system, buses in the New York City Transit (including routes operated by Atlantic Express under contract to the MTA), MTA Bus, and Long Island Bus systems, the PATH subway system, the Roosevelt Island Tram, AirTrain JFK, NJ Transit and Westchester County's Bee-Line Bus System. It is a thin, plastic card on which the customer electronically loads fares. It was introduced to enhance the technology of the transit system and eliminate the burden of carrying and collecting tokens. The MTA discontinued the use of tokens on the subway in May 2003 and on buses on December 31, 2003. The MetroCard is managed by a division of the Metropolitan Transportation Authority (MTA) known as MetroCard Operations and manufactured by Cubic Transportation Systems, Inc.
