To a degree that system is already in place,
How? I don't see any system in place to stop unauthorized items being paid.
My idea about a Pin/Code on the customer signature card was just that, an idea.
The other idea about the merchant giving the bank a copy of the agreement so the bank knows it's authorized is a better one!
I have the best idea, to protect me, I use none of the banks services unless it's absolutely necessary for my benefit!
