If you enable “Save Cards” in the plugin options dashboard, users can pay with one of their cards that they have used for previous orders (and saved). This will spare them the trouble of inserting their data once again.
Users can refer to the complete list of credit cards used right inside “Payment Cards” section on “My Account” page.
Clicking on “Add new”, users will also be able to add the details of a new card, and the card will be available for future purchases as well.
You can also choose whether to automatically register all the cards that users enter or to let them decide every time if they want to save the card or not.
You can set this option from the plugin settings in the Card registration mode section:
If you select Let user choose, then, the system will register cards only when customer ticks the checkbox “Save card” during the payment.
