Yoti IDV, React Native

A react native wrapper of Yoti IDV for Android and iOS. Yoti IDV allows a user of your app to take a photo of their document, as well as to scan or capture their face, we then verify this instantly and prepare a response, which your system can then retrieve on your hosted site.

Prerequisites

To integrate with Yoti IDV, a working infrastructure is needed (see developers.yoti.com for more details or get in touch with us here).

Requirements

• Android SDK 3+
• iOS SDK 6+

Integration

Start your integration by adding the following dependency to your package.json file:

"dependencies": {
    "@getyoti/yoti-doc-scan-react-native": "^4.0.0"
}

Android

Continuing with your integration for Android, add the following property and repository to your project's build.gradle file:

buildscript {
    ext {
        yotiSdkVersion = "3.5.0"
    }
}
allprojects {
    repositories {
        maven {
            url 'https://maven.microblink.com'
        }
    }
}

Now add any of these optional dependencies to your app's build.gradle file:

dependencies {
    // With automatic capture via OCR and NFC capture
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-doc-scan:${rootProject.ext.yotiSdkVersion}"
    // With manual capture only, no OCR, no NFC - around 14Mb smaller in size
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-doc-scan-slim:${rootProject.ext.yotiSdkVersion}"
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-doc-scan-sup:${rootProject.ext.yotiSdkVersion}"
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-liveness-zoom:${rootProject.ext.yotiSdkVersion}"
    // With embedded AI model
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-facecapture:${rootProject.ext.yotiSdkVersion}"
     // Without embedded AI model - around 20 MB smaller in size
    implementation "com.yoti.mobile.android.sdk:yoti-sdk-facecapture-unbundled:${rootProject.ext.yotiSdkVersion}"
}

If you're using Proguard or another obfuscation tool, you should also add the following configuration rules to your proguard-rules.pro file:

-keep class com.yoti.** { *; }
-keep class com.microblink.** { *; }
-keep class com.microblink.**$* { *; }
-dontwarn com.microblink.**
-keep class com.facetec.zoom.** { *; }
-dontwarn javax.annotation.Nullable

iOS

To continue your integration with iOS, you should add the following to your Podfile and run pod install from its directory:

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
require_relative '../node_modules/react-native/scripts/react_native_pods'

platform :ios, '11.0'

target 'TargetName' do
  config = use_native_modules!
  use_react_native!(:path => config[:reactNativePath])
  use_frameworks!
  use_native_modules!
  pod 'YotiDocumentScan'                // Include if `YotiSDKIdentityDocument` is included and to support identity document OCR
  pod 'YotiNFC'                         // Include if `YotiSDKIdentityDocument` is included and to support identity document NFC
  pod 'YotiSDKIdentityDocument'         // Optional
  pod 'YotiSDKSupplementaryDocument'    // Optional
  pod 'YotiSDKFaceTec'                  // Optional
  pod 'YotiSDKFaceCapture'              // Optional
end

In addition, you should add NSCameraUsageDescription to your Info.plist.

And if you have included YotiNFC in your target, make sure to also:

• Add NFCReaderUsageDescription to your Info.plist
• Add com.apple.developer.nfc.readersession.iso7816.select-identifiers to your Info.plist and include A0000002471001 as an application identifier for your app to support
• Turn on Near Field Communication Tag Reading under the Signing & Capabilities tab for your project’s target

Usage

1. Import module

import RNYotiDocScan from '@getyoti/yoti-doc-scan-react-native';

2. Launch a session

Launch a session with its required parameters using the startSession function.

const successCallback = (code, description) => {
    ...
}
const errorCallback = (code, description) => {
    ...
}
RNYotiDocScan.startSession(id, token, successCallback, errorCallback);

3. Customizations

On iOS, you can set the primary colors using the following API:

RNYotiDocScan.setLightPrimaryColorRGB(0, 0, 0); // default: (40, 117, 188)
RNYotiDocScan.setDarkPrimaryColorRGB(0, 0, 0); // default: (145, 190, 255)

To customize the colors on Android, please refer to its separate documentation.

In addition, you can choose to also specify a request code on Android:

RNYotiDocScan.setRequestCode(0); // default: 9001

Supported languages

Yoti IDV supports the 9 languages listed in the table below, but their use is driven by the localization configuration of your target. If your target only supports a subset of our SDK's supported languages, our SDK will fall back to English on the ones your target doesn't support.
