In order to change a member’s card on file, you must impersonate them. First, find the member using the Members page found in the left navigation of your dashboard.
Then, click Impersonate.
You will now see the member’s profile, as they would see it. Under Card Details, click View and Modify.
Click Add Card.
Enter the new card details and click Add Card.
From here, you can choose to change the default card, or remove either of the cards on file.
