Requires a non-Google Voice number to use for some reason. Even though the number on my account is a GV number. No way around it other than to change the number on my account to one I never use. Idiotic.

They don't tell you how to go to merchants who already have your existing credit card number and change it to a virtual number. Still waiting to find that out.

I haven't used it yet. But I think it will help me. At least that's what I am hoping.
