I particularly like the idea, especially after the first payment-processing apps started showing up on the App Store but without any sort of accompanying hardware or ability to capture the credit card number. Just because you need external hardware to read credit cards doesn't mean the hardware isn't feasible for use. Neither does it mean this service needs to require that you swipe a card or only accept credit cards.
I for one would love to have a garage sale with such a device, or to go sell my knitted or baked goods at some gathering somewhere where people without such a mobile device might be at a disadvantage payment-wise. I could also, depending on how durable the external hardware is, see using this in a retail setting to accept credit cards in a convenient manner, like at the Apple Store.
I know my AmEx card has expresspay (pretty much just rfid on your card) so I can just wave my card near a reader instead of swiping, but I can't see that being standardized for all cards, nor can I see that really working out for consumer devices like the iPhone. I could sort of maybe see cameras, but that ends up taking more time than a simple swipe. So why complicate things?
