I don't know about reporting faster. But I had a Chase BP account that I have not used for about 6 years. I activated the card on Tuesday and on Friday (yesterday) I received an "Infromation regarding changes to my account" APR rose to Prime + 20.99 and the reason was to maintain profitability on your account". I was like wow because the card has an annual fee.
Chase must do something when you activate cards. I am wondering if old cards should not be activated until after the new laws go into effect?
