5. Push notifications

NFC Wallet uses push notifications for LCM events, payment key replenishment, and transaction notifications.

On Android, implement push delivery using Firebase Cloud Messaging (FCM).

On Huawei devices without Google Play services, use HMS Push Kit.

What you need to implement

Your digital wallet application must:

• Configure FCM or HMS Push Kit.

• During enrollment, retrieve the push token and pass it to the NFC Wallet SDK.

• Route inbound push payloads from the NFC Wallet backend to the NFC Wallet SDK.

• Handle push token refresh and update the NFC Wallet SDK.
