# INVisualCodeDomainHandling

An interface for adopting all of the protocols in the visual codes domain.

```
protocol INVisualCodeDomainHandling : INGetVisualCodeIntentHandling
```

## Overview

The [`INVisualCodeDomainHandling`](/documentation/Intents/INVisualCodeDomainHandling) protocol is a convenience protocol that adopts all of the protocols used to handle QR codes and other visual codes. You can adopt this protocol instead of adopting the [`INGetVisualCodeIntentHandling`](/documentation/Intents/INGetVisualCodeIntentHandling) protocol.

An object that adopts this protocol must be able to respond to the following intent:

- An [`INGetVisualCodeIntent`](/documentation/Intents/INGetVisualCodeIntent) object is a request for your app to provide a visual code.

Your handler object must be prepared to resolve any parameters associated with this intent and to confirm and handle the requests. When confirming and handling a request, you provide the response object that matches the specified intent.
