I think blind people / screen readers might have difficulty with this interface, too. It's important to keep accessibility in mind when designing futuristic interfaces.
If you press tab, it at least cycles through all of the input boxes on the front side in an appropriate manner, and you could probably design it to flip over on the next tab press. I'm fairly certain that would make it work with screen readers (but not positive).
It doesn't tab between the input boxes or even show the boxes until it's detected the card type based on first four digits. On initial load you get an input box with "XXXX XXXX XXXX XXXX" and nothing else. It does not look like an average credit card form and a lot of people will be confused "where do I put in my name" when they first see it.
I don't know. The current convention is always to enter the credit card number first, then the name later (usually as part of the billing address). Once you start entering your card, the rest of the information is explained nicely.
