During the past two decades, swiping has become a common hustle across the subway system. Swipers, often young men, stand near turnstiles offering MetroCard swipes for two dollars cash—a discount from the official $2.75 fare. Many swipers operate by buying unlimited-ride MetroCards and then trying to sell enough two-buck swipes to surpass the initial capital outlay. Swiping can be a relatively sturdy trade underground.
