The New Credit Card Act of 2009 takes effect on February 22, 2010. To help you prepare, my blog will feature Nine Tips over the next three weeks.

Tip Number Nine

You credit card company will have to give you 45 days notice before they increase your balance with a retroactive credit card interest rate. This gives you time to transfer the balance or pay it off.

Beware: They don’t have to give you notice if you agreed to pay the balance within a set time period on a promotional offer. It also doesn’t apply if your account is past due.
