Good news for credit card holders—the final set of provisions under the Credit Card Act of 2009 take effect today, offering some important consumer protections.
For those who use credit cards responsibly, the new laws will provide more time to pay bills and less likelihood for fees, penalties and interest rate changes. For those struggling with credit cards or facing bankruptcy, the laws may prevent fees from adding up and provide a little breathing room.
Here's a look at some of the key provisions that are now in effect:

• Expanded Statements: Your monthly card statement will have a few new features, including broken down fees and penalties and a chart showing how long it will take to pay off the charges making only the minimum payment (and how much it will cost). Your statement will also arrive at least 21 days before the due date, a full week earlier.
• 45 Day Notices: Your credit card issuer must give advance warning of any changes to your account, particularly interest rate changes. This will give you more time to consider the changes, negotiate with the credit card company, or, if necessary, pay off the balance and close the account.
• No Rate Increases for 1 Year: The new law prohibits "arbitrary" rate increases for the first year you hold an account. Lawmakers hope this will curb "universal defaults", in which one card issuer raises interest rates due to late payment on a card issued by a different bank. Some actions could still trigger a rate increase, such as being more than 60 days delinquent.
• Over-Limit Opt-in: You will only be charged over-limit fees if you agree to it. While this may seem like a blessing, it also means more transactions may be declined.

While these changes went into effect, many cardholders have seen changes to their account over the past year, since the law was introduced. Credit card companies have been preparing for the law to go into effect, and in many cases have not been acting in consumers' best interest.
Many credit card companies have been raising interest rates and introducing new annual fess (which are permitted in the new law) in order to prepare for the revenue losses that could come under the Credit CARD Act.
