The Device Account Number created for your card when you add it to Apple Pay is unique to that specific device and is used to ensure secure transactions with Apple Pay.
This account number does not match your actual virtual card number, preventing your real card details from being disclosed during transactions.
To find the Device Account Number for your payzy card in Apple Pay, follow these steps:
Open the "Settings" app on your device.
Scroll down and select "Wallet & Apple Pay".
Select the payzy card you have added.
The number is displayed under the "Card Information" section.
