The process for PCI customers who wish to remove a saved Credit Card token from a tenants account is fairly simple.
Go to Tenant Information -> Auto Billing Tab
Un-check the “Auto Credit Card Billing” Box. It is the act of un-checking this box that produces a prompt. When prompted select YES to delete the card from the tenants account.
Note: If the box is not currently checked, check and then un-check the box to delete the card.
