Payments

Real pixels attached. Payment screen inspired by Bill Labus' genius payment UX here: http://dribbble.com/shots/570629-Card-Payments

The credit card type would be detected based on the card number, and the logo would appear in the top-right of the card.

Still working on the billing info section. What fields are absolutely necessary?

The country could possibly be auto-filled based on the phone's GPS. State would be based on the zip code. You might even make the assumption that the name would be the same as the name on the card and get rid of that field too. Finally, are two lines really necessary for the address field?

EDIT: Changed the card's border radius to 20px for realism's sake. :) It was bugging me. Check out the new version here: http://dribbble.com/shots/611229-Payments/attachments/50866
