Phones as Credit Cards

Hopefully less people will be losing there phone or breaking it. Though a far way from becoming a replacement for credit cards, smart phones will now be able to be swiped and used as a credit card. Though the article I read stated that this has already been adopted overseas, it seems the one usual suspect is keeping this technology back from use in the United States. Yes, that would be major corporate players all trying to get as much money as they can out of this technology. Who will control it? The phone carriers, the credit card companies, the banks, payment networks, technology companies...I guess once this is figured out we can reach this new millennium of no wallet necessary but not yet.
