NEW YORK — Payment processor Visa Inc. said Saturday that it plans to start separately categorizing sales at gun shops, a major win for gun control advocates who say it will help better track suspicious surges of gun sales that could be a prelude to a mass shooting.
But the decision by Visa, the world's largest payment processor, will likely provoke the ire of gun rights advocates and gun lobbyists, who have argued that categorizing gun sales would unfairly flag an industry when most sales do not lead to mass shootings. It joins Mastercard and American Express, which also said they plan to move forward with categorizing gun shop sales.
