Add the SDK to Your App
This guide shows you how to add the Scandit Data Capture SDK to current existing project.
The latest stable version of React Native CLI and other related tools and dependencies.
A project with minimum iOS deployment target of 13.0 or higher. Or an Android project with target SDK version 23 (Android 6, Marshmallow) or higher.
A valid Scandit Data Capture SDK license key. You can sign up for a free test account at ssl.scandit.com.
Android devices running the Scandit Data Capture SDK need to have a GPU or the performance will drastically decrease.

Add the SDK
Currently we support adding the Scandit Data Capture SDK React Native plugins to your project in two ways. The simplest way is to use the npm registry, alternatively you can manually download the plugins and add them to your project.
You should always make sure to add the scandit-react-native-datacapture-core plugin, as all other plugins depend on it.
1. Create a new project (optional)
If you do not have a React Native project yet that you’ll use, you should create a new one.
> react-native init HelloScandit > cd HelloScandit
2a. Add the Scandit Data Capture SDK from the npm registry
To add our plugins from the npm registry, you can run these commands from your project’s root folder. In the following snippet we’re adding ScanditBarcodeCapture API
yarn add scandit-react-native-datacapture-core yarn add scandit-react-native-datacapture-barcode
You can also specify a version @<version>.
2b. Add the Scandit Data Capture SDK manually
After you download the archive containing all the plugins at ssl.scandit.com/dashboard/downloads, unzip the archive. It includes the available React Native plugins, including the scandit-react-native-datacapture-core plugin that all other plugins depend on.
First add scandit-react-native-datacapture-core plugin:
yarn add <path to scandit-react-native-datacapture-core plugin>
Once this is done, you can continue with adding the plugin for your desired functionality, e.g. for barcode capture, add the scandit-react-native-datacapture-barcode plugin:
yarn add <path to scandit-react-native-datacapture-barcode plugin>
3. Additional steps on iOS
After adding the plugins, you’ll want to make sure they’re added to your iOS project properly:
cd ios && pod install
On Android, the Scandit SDK uses content providers to initialize the scanning capabilities properly. If your own content providers depend on the Scandit SDK, choose an initOrder lower than 10 to make sure the SDK is ready first.
If not specified, initOrder is zero by default and you have nothing to worry about.
Camera Permissions: When using the Scandit Data Capture SDK you will want to set the camera as the frame source for various capture modes. On Android, you have to request camera permissions in your own application before starting scanning. To see how you can achieve this, take a look at our samples: Run our Sample Apps.
Remember that, if you want to use the camera as the frame source for barcode, text and label capture, you need to set the “Privacy - Camera Usage Description” field in the Info.plist file for iOS.
