# 4. Notificaciones push

NFC Wallet SDK usa notificaciones push para enviar actualizaciones de tarjetas digitales.

En iOS, implementa la entrega push usando **Firebase Cloud Messaging (FCM)**. FCM usa el servicio Apple Push Notification (APNs) para llegar a los dispositivos.

### Lo que necesitas implementar

Tu **aplicación de monedero digital** debe:

* Solicita permiso para notificaciones y regístrate en APNs.
* Obtén el token de registro de FCM.
* Envía el token al SDK de NFC Wallet para que el backend de NFC Wallet pueda enviar notificaciones push al dispositivo.
* Dirige y procesa las notificaciones push entrantes de NFC Wallet.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.payments.thalescloud.io/nfc-wallet-sdk-ios/es/get-started/configuration/4.-push-notifications.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
