What would actually be slightly lower in cost and leverage existing infrastructure better would be this Plastc card but remove the bluetooth, the touch interface, chip-n-pin, and the internal battery. Just have an app on your NFC phone and have it send the card data over NFC to the card when you want to use it. In this way you could just have an app on your phone which can work with the bank over the Net to generate throw-away numbers for every transaction.
Having any credit card number which you've ever used only usable for one single purchase would make fraud have to change to adapt. But you could probably sell such a thing easily today with all the recent loss of credit card number news. Granted, the vendor of such a card has to partner with a bank to enable this feature set, and then only a small number of people will want such a card as it imposes a new workflow for paying for things.
Yes. Keep all your financial information on a general purpose consumer computer accessible over the network, and never worry about the safety of your financial data ever again ;)
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.
