US driving license issue in android phone using blinkid-phonegap plugin

[jassiwaliaVC]

Below is the code for US driving license but i am able to scan 2 out of 20 US driving cards from pdf in my PC. And same cards i scanned with Blinkid official app from playstore it scanned 11 out of 20 cards. Please correct me if i m using wrong code.

scan() { let usdlCombinedRecognizer = new window.cordova.plugins.BlinkID.UsdlCombinedRecognizer(); usdlCombinedRecognizer.returnFaceImage = true; usdlCombinedRecognizer.returnFullDocumentImage = true;

let usdlSuccessFrameGrabber = new window.cordova.plugins.BlinkID.SuccessFrameGrabberRecognizer(usdlCombinedRecognizer);

// create RecognizerCollection from any number of recognizers that should perform recognition
let recognizerCollection = new window.cordova.plugins.BlinkID.RecognizerCollection([usdlSuccessFrameGrabber]);
recognizerCollection.allowMultipleResults = true;
// package name/bundleID com.microblink.blinkid
let licenseKeys = {

Hi @jassiwaliaVC,

when using combined recognizer, in your case UsdlCombinedRecognizer, don't wrap it with SuccessFrameGrabberRecognizer. Add only usdlCombinedRecognizer to recognizer collection, and when result is obtained instead usdlSuccessFrameGrabber.slaveRecognizer, use usdlCombinedRecognizer directly.

@i1E no luck this is my updated code, can u plz edit my code if it is wrong

scan() {

let usdlCombinedRecognizer = new window.cordova.plugins.BlinkID.UsdlCombinedRecognizer();
usdlCombinedRecognizer.returnFaceImage = true;
usdlCombinedRecognizer.returnFullDocumentImage = true;

let documentOverlaySettings = new window.cordova.plugins.BlinkID.DocumentVerificationOverlaySettings();

// create RecognizerCollection from any number of recognizers that should perform recognition
let recognizerCollection = new window.cordova.plugins.BlinkID.RecognizerCollection([usdlCombinedRecognizer]);
