It's a cute interaction, but for credit-card forms you want to be obvious rather than cute. Showing all the fields a user expects to fill out instills confidence and prevents questions like "where do I input my name and card expiry date?" "what about the security code?" "where is the billing address?" etc. People would typically not start filling out their credit-card details with those doubts in their minds.

One additional nitpick - it says "YourBank" at the beginning, so while I was aware this was supposed to a credit-card form because of the title of the submission, it can also be mistaken for a bank account number submission.
