Fact No. 1 of 8: No cap on credit card interest

So today you got an offer for another credit card through the mail.
And you are thinking...
Wow! That low rate looks good compared to what I am paying on my other credit card, maybe it's time for me to get one with a lower rate.

STOP!!!!
Think again about this before you jump in uninformed.

Even if you sign up for a new credit card at its low interest rate, here's a scary, little-known fact: Many card issuers can raise interest rates as high as they like, whenever they like.

The top 10 banks that issue credit cards are federally chartered banks and do NOT have to follow state laws limiting interest rates, says Chi Chi Wu, staff attorney at the National Consumer Law Center.

"So they are free to set the rates as high as they want," Wu says.

Your interest rate is only protected for the card's first year (or first six months, if it's a teaser rate), under the Credit Card Accountability, Responsibility and Disclosure Act, or CARD Act. If you go 60 days late on a payment, that protection disappears. A variable rate tied to an index can also increase if the index goes up.

But if you've had the card for more than one year, the issuer can hike your rate even if you've been a model customer, says John Ulzheimer, president of consumer education for SmartCredit.com.

Two caveats, courtesy of the CARD Act: That hike applies only to new charges (your current balance will be assessed the old rate). And the issuer has to give you 45-day advance notice. This notice may come in with your bill, you know the paper you throw away without even bothering to look at... maybe it's time you actually read some of those papers to stay up to date on what's happening with your interest rate.
