# Establecer la tarjeta de pago predeterminada

## Resumen

La tarjeta digital predeterminada es la tarjeta que su **aplicación de billetera digital** muestra primero durante el pago sin contacto.

El usuario final puede conservar la tarjeta digital predeterminada o cambiar de tarjeta desde su interfaz antes de confirmar el pago.

Para opciones de UX de pago, consulte [Pago sin contacto](/nfc-wallet-sdk-ios/es/implement-nfc-wallet/make-payments/implement-contactless-payment.md).

### Integración del SDK

Llame a `DigitalCard.setDefault()` en el `DigitalCard` que desea establecer como predeterminado.

El siguiente ejemplo establece la tarjeta digital predeterminada:

{% code title="Establecer tarjeta predeterminada" %}

```swift
func setDefaultCard(digitalCard: DigitalCard) async {
  do {
    _ = try await digitalCard.setDefault()
  } catch {
    // Manejar errores.
  }
}
```

{% endcode %}

{% hint style="info" %}
Puede establecer una tarjeta digital como predeterminada solo cuando está activa.

La tarjeta también debe tener al menos una clave de pago restante.

Use las propiedades en [Obtener detalles de la tarjeta](/nfc-wallet-sdk-ios/es/implement-nfc-wallet/manage-digital-cards/display-digital-cards.md#get-card-details) para validar ambas.
{% endhint %}
