Ask one of the banks about the provisioning of the card. Cards (accounts) and device are evaluated for the risk they present. Cards are the classified as Green Path/Flow, Yellow Path, Orange Path or Red Path. Red Path is an automatic decline.
Apple is not your bank. They cannot approve or decline adding a card to the device. They provide some basic information about the device, but the bank must decide whether to add the card or not.
The provisioning involves several parties, your bank, Payment Network Operator (Mastercard, Visa, etc.) Token Service Provider (TSP). The PNO and TSP also may provide your bank with information, in addition to Apple.
Information Apple provides includes,
>>When you are adding a payment card like store, credit, debit, and prepaid cards to Apple Pay, information you provide about your card, and whether certain device settings are enabled may be sent to Apple in order to determine your eligibility to enable Apple Pay. Your device may also evaluate device use patterns (for example, percent of time device is in motion, approximate number of calls per week) to help identify fraud. The information evaluated by your device is not shared with Apple in a way that can be linked to you.
Information may also be provided by Apple to your card issuer, payment network, or any providers authorized by your card issuer to enable Apple Pay, in order to determine the eligibility of your card, to set up your card with Apple Pay, and to prevent fraud, including:
- Your credit, debit, or prepaid card number
- The name and billing address associated with your Apple ID, iTunes, or App Store account
- General information about your Apple ID, iTunes, and App Store account activity (for example, whether you have a long history of transactions within iTunes)
- Information about your device and, if using Apple Watch, the paired iOS device (for example, a device identifier, phone number, and the name and model, for both your Apple Watch and paired iOS device)
- Location at the time you add your card (if you have Location Services enabled)
- Account or device history of adding payment cards
- Aggregated stats relating to the information from payment cards you’ve added or attempted to add to Apple Pay<<

I’m certain your card has been red pathed by your bank. If it were Yellow or Orange path you’d be proceeding to final verification steps.
