Experian®, the global information services company, released its findings today on credit card trends, which provide insight into U.S. card usage. The study shows that nationally, consumers are opening 26 percent fewer credit cards* than they were three years ago. The study also reveals that out of the top metropolitan areas studied, the number of open bank cards were typically higher than retail credit cards, with the exception of four areas — Pittsburgh, Miami, Columbus and Atlanta — whose residents seem to favor their retail cards.
