Metcard was the brand name of an integrated ticketing system used to access public transport in Melbourne, Australia. It was a universal ticket which allowed users to ride on the city's Metlink and Metropolitan Transit Authority network, consisting of suburban trains, trams, and buses, including the NightRider network. The Metcard was a credit card-sized ticket made out of cardboard and used a magnetic strip to store fare data. Metcard was operated by OneLink Transit Systems under a contract with the Government of Victoria which was managed by the Transport Ticketing Authority.
