How to create a React Native Document Scanner

By using the Docutain Document Scanner SDK, one can add a high-quality scanner into an existing React Native app.


Why integrate scanning?
The main goal of integrating scanning functionalities is to be able to do the document recognition within the camera frame in real time to make the document scanning process as easy as possible.

More sophisticated scanner apps like Docutain do not stop at this point. Once the document was scanned successfully, OCR text recognition is run. With this, one can get two things:

Searchable PDF files, as they include the recognized text
Intelligent Data Extraction, e.g. invoice or address data
Building a high quality cross-platform document scanner app from scratch takes a lot of time, effort and knowledge in a lot of different specializations.

Therefore, the following tutorial will help: https://sdk.docutain.com/blogartikel/how-to-create-a-react-native-document-scanner

It will give an overview over the following steps:

  • Getting started
  • Implement the Document Scanner React Native
  • Document Scanner Configuration
  • Add OCR Text Recognition Feature
  • Add Data Extraction Feature

Prerequisites
Based on a Windows development platform, the following prerequisites should be considered:

  • Visual Studio Code 1.75 or later with the React Native extension for VS Code

  • Android Studio 2022.3 (Giraffe) or later with the React Native plugin for IntelliJ

  • IntelliJ IDEA 2022.3 or later with the React Native plugin for IntelliJ
