    BlinkCard SDK wrapper for React Native

    Best-in-class credit card 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 BlinkCard 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)


    • Generate a free trial license key to start using the SDK in your app (registration required)

    • For production licensing, please contact sales to request a quote.

    Keep in mind: Versions 2.2.0 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

    BlinkCard React Native was built and tested with React Native v0.64.0


    First generate an empty project if needed:

    react-native init --version="0.64.0" NameOfYourProject

    Add the blinkcard-react-native module to your project:

    cd <path_to_your_project>
    npm i --save @microblink/blinkcard-react-native



    Link module with your project:

    react-native link @microblink/blinkcard-react-native

    CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like BlinkCard in your projects.

    Download and install/update Cocopods version 1.10.0 or newer.

    • 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 @microblink/blinkcard-react-native depends on latest MBBlinkCard 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


    Add microblink maven repository to project level build.gradle:

    allprojects {
      repositories {
        // don't forget to add maven and jcenter
        // ... other repositories your project needs
        maven { url "" }


    This repository contains script that will create React Native project and download all of its dependencies. You can run this script with following command:



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


    Can I create a custom UI overlay?

    Yes you can, but you will have to implement it natively for android and ios, you can see native implementation guides here(Android) and here(ios).

    Known react-native problems:


    React native v0.62.2

    ** [NSURLResponse allHeaderFields]: unrecognized selector sent to instance**

    Make sure to use the Flipper version 0.37.0 in your Podfile:

    versions['Flipper'] ||= '~> 0.37.0'

    React native v0.63.0

    'event2/event-config.h' file not found

    Remove Flipper from Podfile
