# Document Detector (DEPRECATED)

{% hint style="info" %}
This library provides a React Native bridge for our native SDKs. The versions currently in use are as follows:

* Android: `com.combateafraude.sdk:document-detector:9.4.1`
* iOS: `DocumentDetector, 16.0.3`
  {% endhint %}

The `@caf.io/react-native-document-detector` library captures identity documents such as RG, CNH, RNE, and others with high quality and data extraction assurance. Instead of using a basic camera, leverage our smart camera with automatic capture and document detection to improve onboarding by avoiding low-quality or undocumented photos.

## Terms & Policies

When using our SDKs, please make sure that you agree with our [Privacy Policy](https://en.caf.io/politicas/politicas-de-privacidade) and our [Terms and Conditions of Use](https://en.caf.io/politicas/termos-e-condicoes-de-uso).

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.caf.io/caf-sdk/react-native/standalone-modules/document-detector.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
