BlinkID SDK wrapper for React Native
Best-in-class ID scanning software for cross-platform apps built with React Native.
Below, you’ll find a quick guide on starting your own demo project as well as complete guidance on installing and linking BlinkID library with your iOS and Android apps ⬇️
For a full access to all features and functionalities, please consider using our native SDKs (for iOS or Android)
Licensing
-
A valid license key is required to initialize scanning. You can request a free trial license key, after you register, at Microblink Developer Hub
-
For production licensing, please contact sales to request a quote.
Keep in mind: Versions 5.8.0 and above require an internet connection to work under our new License Management Program.
We’re only asking you to do this so we can validate your trial license key. Scanning or data extraction of identity documents still happens offline, on the device itself.
Once the validation is complete, you can continue using the SDK in offline mode (or over a private network) until the next check.
React Native Version
BlinkID React Native was built and tested with React Native v0.75.0
Installation
First generate an empty project if needed:
react-native init --version="0.75.0" NameOfYourProject
Add the blinkid-react-native module to your project:
cd <path_to_your_project>
npm i --save blinkid-react-native
Linking
iOS
Link module with your project:
react-native link blinkid-react-native
CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like BlinkID in your projects.
- If you wish to use version v1.4.0 or above, you need to install Git Large File Storage by running these comamnds:
brew install git-lfs
git lfs install
- Be sure to restart your console after installing Git LFS
Installing pods
From react-native 0.60 CocoaPods are now part of React Native's iOS project.
Go to NameOfYourProject/ios
folder and install Pods
pod install
Our blinkid-react-native
depends on latest PPBlinkID
pod so it will be installed automatically.
To run iOS application, open NameOfYourProject.xcworkspace, set Your team for every Target in General settings and add Privacy - Camera Usage Description key to Your info.plist file and press run
Android
Add microblink maven repository to project level build.gradle:
allprojects {
repositories {
// don't forget to add maven and jcenter
mavenLocal()
jcenter()
// ... other repositories your project needs
maven { url "http://maven.microblink.com" }
}
}
Sample
This repository contains initReactNativeSampleApp.sh script that will create React Native project and download all of its dependencies. You can run this script with following command:
./initReactNativeSampleApp.sh
Video tutorial
Step by step guide how to start blinkid-reactnative sample app. A tutorial flows from cloning repository via git clone to successfully deployed sample application on Android and iOS device with real-time screen mirroring. Application sample contains the simple use of USDL recognizer with Ontario drivers license card.

Using documentVerificationOverlay and CombinedRecognizer
This video tutorial describes how to use documentVerificationOverlay with UsdlCombinedRecognizer.
DocumentVerificationOverlay is overlay for RecognizerRunnerFragment best suited for combined recognizers because it manages scanning of multiple document sides in the single camera opening and guides the user through the scanning process. It can also be used for single side scanning of ID cards, passports, driver’s licenses, etc

Usage
To use the module you call it in your index.android.js or index.ios.js file like in the sample app. Available recognizers and API documentation is available in JS API files.
