Starting in January, Pen Fed will start offering 5% cash back on gas at the pump on its Visa Platinum Cash Rewards credit card for both new and existing card holders. In and of itself, a credit card with 5% cash back on gas is good, but not great. When you combine it with the other features of the Pentagon Federal cash back card, however, it becomes an excellent card choice.

In particular, the card features 1.25% cash back on all other purchases, credited monthly on your statement. Also, of note is that Pen Fed does not charge an additional fee for transactions made in foreign currencies (a rarity these days), other than the standard 1% fee that Visa charges, which makes it ideal for use when travelling.
