It appears you can pay any bill, yep including your mortgage. Now before you get too googlieyed look at the fees. Kind of takes the luster off it doesn't it.
At least someone is giving the opportunity to pay using a cc. Surely someone else will follow with better terms.
I also don't like the fact they request your Driver's license Number and your SS#. People can steal your identity with that much information about you.
