SmartLink is a RFID-enabled credit card-sized smartcard that is the primary fare payment method on the PATH transit system in Newark and Hudson County in New Jersey and Manhattan in New York City. It was designed to replace PATH's paper-based farecard, QuickCard, and there was plans to expand its usage throughout most transit agencies in the tri-state area. The SmartLink card has been available to the public since July 2, 2007. Although the MetroCard used in the Metropolitan Transportation Authority (MTA) can also be used on the PATH, the reverse is not true for SmartLink, as it cannot be used when riding in the MTA.
