Getting Started

First, cd to your RN project directory, and install RNMK through rnpm . If you don't have rnpm, you can install RNMK from npm with the command npm i -S rnkit-excard-idcard and link it manually (see below).

iOS

• #### React Native < 0.29 (Using rnpm)

  rnpm install rnkit-excard-idcard

• #### React Native >= 0.29 $npm install -S rnkit-excard-idcard

  $react-native link rnkit-excard-idcard

Manually

1. Add node_modules/rnkit-excard-idcard/ios/RNKitExcard.xcodeproj to your xcode project, usually under the Libraries group
2. Add libRNKitExcard.a (from Products under RNKitExcard.xcodeproj) to build target's Linked Frameworks and Libraries list
3. Add ocr framework to $(PROJECT_DIR)/Frameworks.

Android

• #### React Native < 0.29 (Using rnpm)

  rnpm install rnkit-excard-idcard

• #### React Native >= 0.29 $npm install -S rnkit-excard-idcard

  $react-native link rnkit-excard-idcard

Manually

1. JDK 7+ is required
2. Add the following snippet to your android/settings.gradle:

include ':rnkit-excard-idcard'
project(':rnkit-excard-idcard').projectDir = new File(rootProject.projectDir, '../node_modules/rnkit-excard-idcard/android/app')

1. Declare the dependency in your android/app/build.gradle

dependencies {
    ...
    compile project(':rnkit-excard-idcard')
}

1. Import import io.rnkit.excard.EXOCRPackage; and register it in your MainActivity (or equivalent, RN >= 0.32 MainApplication.java):

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.asList(
            new MainReactPackage(),
            new EXOCRPackage()
    );
}

1. Add Module ExBankCardSDK And ExCardSDK In Your Main Project.

Finally, you're good to go, feel free to require rnkit-excard-idcard in your JS files.

Have fun! 🤘
