1. Your old card has expired (expiry date reached) and you will receive a new card: You do not need to do anything. Your new card will be automatically available in Apple Pay once you have activated it. To activate a card, simply conduct a transaction using your PIN (withdrawal from an ATM, payment in store, etc.).
2. Is your card was blocked/stolen, it has been replaced: As such, you must add your new card to Apple Pay.
How do I activate Apple Pay from my BILnet mobile app?
