Is the camper's credit card information saved for future payments?

Yes, when you hit the settle button, a payment window will populate. If you click into the field that says "credit card" a scroll menu will populate. You can then scroll to the bottom to find any credit cards that have been saved on file. 

If you don't see the "One File Credit Card" option right away, make sure to scroll down to find it.

An account can have multiple credit cards saved on file. To add a new one, select the credit card option and type in the new credit card information in the field below.
