Unable to add payment method on my Apple ID as it keeps declining cards

Check this resource about what to do if your payment method is declined in the App Store or iTunes Store. Click here --> If your payment method is declined in the App Store or iTunes Store - Apple Support

- Apple is checking with your financial institution if the payment method is valid and receiving a negative response. Make sure the name and address are entered exactly as it appears on your financial institution bills and that the 3 digit CVV is correct. Check with your financial institution about the status of your card.

- Make sure your payment method is up to date or to try a different one ( If you need to change or update your Apple ID payment method - Apple Support ).

- Make sure this is one of the payment methods that you can use with your Apple ID ( Payment methods that you can use with your Apple ID - Apple Support ) A solution may be to use a method from the same country as the store you are using, but Apple no longer states either way if this is a requirement (it used to say, "Make sure that the billing address for your payment method matches the billing address for your Apple ID" but has now downsized this to "You might need to ask your financial institution to allow international purchases on your debit or credit card." in: If your payment method is declined in the App Store or iTunes Store - Apple Support .

・Unfortunately the list is somewhat general and does not list individual brands of cards (I guess there are too many and are constantly changing).

・Also read any footnotes in the document.

・Finally, note that the document only says which methods _are_ acceptable. Apparently certain types (usually a credit or debit card) _must_ also be present under certain situations such as when a subscription is involved.

Why won’t you accept my “bank card for payment? Why does it keep getting declined? Can you please tell me why

I’ve just tried to pay for flights online and Apple Pay declined payment. Called bank, transferred to their security department and they have confirmed no blocks on my card their end. Sometimes Apple Pay block payment. That’s great, I assume it’s a security thing their end, but how do I confirm with them that it’s safe to unblock it?
