Saving Payment Information

[mahithedula]

Card:
As a regular customer, I want to save my credit card information, so that I do not have to go through the hassle of reentering my credit card number every time I want a donut.

Conversation:
It should be optional to save credit card information through a switch
This is done through a separate screen before entering the payment information where the user can choose to pick their saved information or enter in the information
The information must be valid
Proper security protocols must be put in place to ensure that this sensitive information is not breached

Confirmation:
Once I place an order, I should see a screen with my previous saved payment information and/or the option to enter new payment information before I confirm my order. Then when I want to make another order, I can see this new payment information if I save it.

We no longer have to work on this since the Payment API requirement has been withdrawn.
