You can display the payment card data in the accounting document using document display and line item display.

To do this, choose Extras → Payment card data in document display mode.

When displaying line items, you should define a separate variant for payment card data which contains the fields you require for displaying this data. To do this, choose the special variant "with Credit Cards". To learn how to define variants, refer to the section "Displaying line items" in the document FI - Document Posting.
