4. Push notifications

NFC Wallet SDK uses push notifications to deliver digital card updates.

On iOS, implement push delivery using Firebase Cloud Messaging (FCM). FCM uses Apple Push Notification service (APNs) to reach devices.

What you need to implement

Your digital wallet application must:

• Request notification permission and register with APNs.

• Retrieve the FCM registration token.

• Send the token to the NFC Wallet SDK so the NFC Wallet backend can send push notifications to the device.

• Route and process incoming NFC Wallet push notifications.
