Fed adopts new rules to protect credit card users [AP]

From the AP article:

The Federal Reserve on Tuesday issued sweeping new rules to better protect Americans from sudden hikes in interest rates on credit cards.

...

The Fed wrote the rules to carry out provisions of legislation passed by Congress and signed into law by President Barack Obama last year. Other provisions of that law are slated to go into effect later this year.

We'll see what effects it will have on cash-back credit card programs.
