Have you ever wondered about the best credit card in the country? The October issue of Consumer Reports turned its attention to a survey of this all-important industry. The single best card to have in your wallet is USAA Federal Savings Bank of San Antonio's MasterCard. This card is exclusively for members of the military, their families and in some cases certain retirees. This little piece of plastic was singled out because of its reasonable interest rates and cash back earnings. USAA also delivers the best focus on customers and problem resolution, according to the report. But what about a good card for those of us who aren't in the military? A card issued by Navy Federal Credit Union came in second, while cards issues by credit unions in general took third place. Credit unions offer their cardholders good problem resolution and better interest rates than a typical bank-issued card. Overall, the only big issuers who got decent scores were American Express and Discover. The other major companies, meanwhile, were in the toilet. Providian was named the single worst card issuer. Following right behind at the bottom were Capital One, Bank of America's MBNA division and JP Morgan Chase.
