Visa @ Bank of America offers Automatic Payment - automatically deducts the amount from a corresponding checking account to pay the credit card account. I like this option because you don't have to think about transferring enough money to your credit card on time every month. Do other credit cards / banks offer such option?

Yes, this is pretty standard. Chase / Bank One do that, too. MBNA is a partner with CheckFree which is a bill paying service that provides similar functionality.
