You have the option to edit or remove any previously used payment method as well as change the default method that is first shown at checkout.
Once you are logged into your Rivly account, proceed to your Profile page under the user dropdown.
On this Profile page, you will see a list of sections on the left, one of which is called Payment Methods.
In this section, you have the ability to edit or delete any saved payment method from the results shown as well as specify which card you would like to be your default payment method shown at checkout. Each update or new payment method entered will undergo a subsequent authorization check and fraud risk analysis to ensure that it is indeed a valid payment method. You will be notified of any issues which may require you to return to this page in order to update and resolve the problem.
