- Apple is checking with your financial institution if the payment method is valid and receiving a negative, or no, 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 Account payment method - Apple Support ).

- Make sure this is one of the payment methods that you can use with your account, as listed in this support article: Payment methods that you can use with your Apple Account - Apple Support .

・Unfortunately the payment methods list is somewhat general and does not include individual brands of cards (I guess there are too many and are constantly changing). This thread is an example of where a person was not using an acceptable kind —> Why are my cards not supported on the MFI… - Apple Community

・Also read any footnotes in the document.

・If you are trying to use a payment method from another country you may encounter problems. Apple nowhere states outright your payment method must come from the same country as that to which your ID is set, but some contributors to the forum (none of us work for Apple) say—without any substantiation on Apple's part—this is the case. In fact what Apple says about international payment methods is found in If your payment method is declined in the App Store or iTunes Store - Apple Support where it says: "You might need to ask your financial institution to allow international purchases on your debit or credit card". It could be there is some other unstated requirement that raises problems such as the billing address for the card must be in the same country as your account country even if the issuer is a foreign bank. Apple does not say but usually it is easiest to just use a card from the same country as your Apple Account setting.

・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.
