When a customer is making a purchase on your store, he or she will be able to see the Authorize.net option.
If they already have an account, they will be able to use one of their saved credit cards which is identified by only the last four digits for security reasons.
The customer can also enter new credit card information.
Once they have added the new card information, they can also go to their account to update, edit, add and delete their credit cards.
By clicking the "New Card" button in the Saved Credit Cards page, the customer will be able to select its type, number and his or her contact and billing information.
It is not possible to view any other details on this list as the credit card information is securely stored on Authorize.net.
