To update your billing information locate the settings tab on the left menu.

Now go to the "Subscription" tab. You will see a button "Update Payment and Billing Address". This will open up MemoryShare's billing portal. This is a secure portal(powered by Stripe), that allows you to enter your credit card details.

Click the pencil icon to update your credit card.

You now have two cards stored to your account. Your original card will still be the default card.

Adding a card does not update your default card. Your previous payment method will still be charged. To update your default method click on the 3 dots next to the card you would like to make your default payment method. Select "Make Default"

If you have two cards stored to your account, you can delete the old card by clicking the "x" to next to the expiration date.
