J.P. Morgan Chase & Co. and Visa Inc. said Wednesday that Chase customers can soon use their Visa contactless cards to ride subways and buses in New York City. The use of the tap-to-pay cards will start May 31 for the 4, 5 and 6 subway lines between the Grand Central-42nd Street station in Manhattan to Brooklyn's Atlantic Ave.-Barclays Center station, and on all Staten Island buses. "Over time," all subway lines and buses will accept the contactless cards, the companies said. "Contactless payments have shaped the way consumers pay all over the world, saving valuable time and delivering a fast, easy and secure way to pay," said Dan Sanford, Visa's global head of contactless payments. J.P. Morgan Chase's stock slipped 0.4% in premarket trade and Visa shares edged up 0.2%, while futures for the Dow Jones Industrial Average declined 95 points, or 0.4%.
