Imporving Credit Card Usability

Daily UI - 02 - Credit Card Checkout
So I've been thinking how to make the daily UI even better, and I thought of an app that I use a lot, but has (in my opinion) not the great UX/UI as for the credit card checkout.

This is "Pedidos Ya" an app that I use to order takeout food to my home. This is the process I thought it would be best. I wish that I could show you the current flow, but I'm not a Dribbble pro yet :P.

Have a great week!
