To change your saved card details you need to be logged into the Moonpig website.
Because your card details are kept securely you must be in the secure area of our website in order to remove the details.
The easiest way to do this would be to change the details next time you are making a purchase. When you click on the Checkout button, your saved card details will be shown onscreen. Click on the 'Remove Card' option.
Moonpig do not store your card details instead our trusted partners at Stripe who are a level 1 PCI compliant payment service provider and who specialise in this type of security, keep your information safe.
