The original card will automatically charge on the day of the trip unless you adjust the collection settings on the listing to collect it days earlier. You can also collect the remaining manually at any time before then.
Or, you can update the customer's card in their Customer account.
Access the customer's account this way:
1. Search their name in the Customer's tab or find their name in the booking details.
2. You'll see a line below their name with the last 4 digits of their current card and a small button to edit.
3. Enter the new card number and save it.
