Cycling your unused credit cards back into the mix

Many of us have what are called -- in credit card lingo -- "back of the wallets." These are the cards we hardly ever use that may be buried somewhere in our wallets or in a drawer at home.

The typical American has about a dozen cards, but only 2 that are used frequently. The rest of those cards are ignored until they go dormant. In fact, you may not even activate the new card when you get it in the mail.

Banks used to just let these dormant accounts sit and hope you'd someday use the card again -- but not anymore. Now if an account goes stale, they'll close that account. That hurts your credit score and limits your access to funds.

So you may want to consider using your "back of the wallets" twice a year about 6 months apart. Charge a nominal amount and then pay it off. That will keep these accounts current in your credit mix and raise your credit score.

This is not just a silly assignment. You'll be helping your score, which is very important in getting lower interest rates, securing job offers and more.
