I already do this. Amazon knows my credit card info, so do many other merchants. If I'm doing any kind of mobile payments thing then my phone has access to my bank somehow, too. My concept is basically just "mobile payments" but enabling it for locations where merchants don't have the infrastructure yet. The added benefit is every transaction has a different card number, so merchants who store card numbers and get hacked provides no benefits to the thieves. Granted, any of the mobile payments things should be doing this kind of security thru obscurity, but I have no idea if they are. This is not novel.
