How to add new cards on Apple ID?

If you need to change or update your Apple ID payment method

(Also includes Mac, PC)

Here is how you update your payment method on an iPhone or iPad:

1. Open the Settings app.

2. Tap your name.

3. Tap Payment & Shipping (formerly Media & Purchases). You might be asked to sign in with your Apple ID.

4. Tap Add Payment Method, enter the new payment method, then tap Done.

5. Tap Edit.

6. Tap the red delete button next to the old payment method, then tap Delete.

Also note: "If you change your address, the credit or debit card information that you use with your Apple ID might be automatically updated by your financial institution, and you don't need to take action. But if there's an issue [such as you having a subscription or being a Family Sharing Organizer], add a new card first, then remove the old card."

First confirm that your Expiration date did not get updated automatically. If your bank supports it, there is nothing you would need to do. If your bank does not support that, then you will need to add the new one and remove the old one.

The relevant portion is here:

If your card expires or you otherwise get a new card:

• The card number and expiration date linked to the Device Account Number should be updated automatically. 
• If your card issuer doesn’t support these updates, you might need to remove the card and add it again.

You're welcome. I'm sorry my response apparently contained irrelevant information.
