It’s not possible to update your card’s expiry date. Instead, simply remove the old card from your account and make a new deposit with your new card details.
To remove your card, click the '...' icon in your card deposit section. For more information on removing cards, please click here.
Once your old expired card has been removed, simply make a deposit with your new card (with the updated expiry) and you will be all clear to deposit freely with your new card moving forward.
