Very nice! To make it better:

- ALL of the inputs should look like inputs and only after a user has put in their information should the input ui disappear and the text be shown as it is on a real credit card. Otherwise the ability to enter your name and expiration is ambiguous.

- I don't like how AFTER you enter your full credit card number, the input fields become segregated, trying to change the credit card number becomes difficult as you now have to click on each of the 4 new text fields to enter a new credit card number. (If a card fails to go through a user might try to use a new one). Yes you can just hold down BackSpace and it will travel from field to field deleting the number but that's not obvious for a user to figure out. Don't segregate the numbers into separate fields just leave them in one.
