The PenFed Visa® Platinum Cash Rewards Card offers one of the best cash back rewards program on gas purchases in the nation. You must be a member of Pentagon Federal Credit Union to apply, but membership is open to anyone. Here are some more details on this great cash back card:

Low interest rate. Many rewards cards charge higher interest rates, but through June 30, 2014, the highest interest rate you'll pay on purchases is 9.99%. And, if the prime rate adjusts lower, you get to benefit because your rate will lower as well.

LIMITED TIME: Low balance transfer rate of 1.99% for 24 months and low balance transfer fee. If you transfer your balance before March 31, 2012, you'll only pay an APR of 1.99% for 24 months and a low balance transfer fee of 1% (normally 3%). What's the difference between a balance transfer rate and a balance transfer fee?

Earn a full 5% cash back on gas when you pay at the pump. Other cards offering high cash back may place heavy restrictions on when and how you qualify to earn it. However, you'll earn a full 5% cash back on every single dollar of gas* you buy using this card. *This full 5% cash back does not apply to gas purchased for your boat or airplane (likely determined by the amount of gas purchased in a single transaction); these purchases will earn you 0.25% cash back.

Any other purchases earn you cash back at the rate of 0.25% cash back. You'll still earn cash back on every dollar you charge to your PenFed Platinum Visa card.

Easy automatic redemption of cash back. You get to enjoy your cash back rewards each and every month because they're automatically credited to your account. This makes redemption quick, easy, and effortless.

High credit limits offered. After your credit has been reviewed, you may receive a credit limit of up to $50,000 based on your credit worthiness.

No annual fee is charged to cardholders.
