All credit card owners should be on their toes.

Since Congress passed major changes to the credit card laws back in May, credit card companies have been testing the waters with new plans, rates and tactics. You should read the fine print on your next credit card statement because you could be part of the experiment.

Case in point: Bank of America. The Associated Press reports that the bank is going to begin charging a a new group of  card holders $29-99 in annual fees.

Bank of America is the third largest issuer of credit cards, according to the AP. They say that this is only a “test” going out to a limited number of card holders, but if BoA likes the new revenue it will likely be rolled out to more cardholders.

The AP said that credit card users “in good standing who never carried a balance — and never incurred interest charges or late fees — could be among those getting notices.”

Of course, the fees are optional. If you don’t want to pay you can decline, but Bank of America will close your credit card – which could impact your credit score – the report says.

What does this mean for you? If you have a card with Bank of America start looking at your monthly statements now. Card companies must disclose new fees and rate changes well in advance of their start date now, so you may be getting a notice in the next few months.

Then, you’ll just have to make a decision on whether the fees are worth the value you get from your card. And if you think that earning points is enough to justify paying $99 a year then you better be getting some sweet rewards.

Also, even if you don’t have a Bank of America card you’ll want to check your statements for notices and changes. Any card company looking to start a new program in the new year may send you a notice in the next two months. So be aware of changes and get ready to make some choices.
