How do I reorder my payment methods in Apple Pay?

Do you wish to re-arrange the order of credit / debit cards that you have added in the Wallet app? If YES, then open the Wallet app and then TOUCH & DRAG the cards up or down in the order that you wish. The card that ends up all the way in the bottom will be the default card.

If the above is not what you are asking, then provide some more details on what you are looking for. Thanks.
