Follow the following steps to add components to your page


1. Add needed tag to your page

For Face:
<idt-face-camera-web id="face" options="off" capture="manual" ></idt-face-camera-web>
For ID Card
<idt-card-camera-web id="card" type="card" cardtype="tz" options="off" scan="ocr"  capture="manual"></idt-card-camera-web>

<idt-card-camera-web id="card-back" type="card-back" cardtype="mz" options="off" scan="mrz" capture="manual" read="auto"></idt-card-camera-web>

Tag Options/Attributes

2. Listen for events in your page / component

const  faceCameraWeb = document.querySelector('idt-face-camera-web');
faceCameraWeb.addEventListener('faceImageComputed', (e) => {
	const  data = e.detail;
const  cardCameraWeb = document.querySelector('idt-card-camera-web');
cardCameraWeb.addEventListener('cardImageComputed', (e) => {
	const  data = e.detail;
	// your code to process
const  scanResponse = document.querySelector('idt-card-camera-web');
cardCameraWeb.addEventListener('scanResponse', (e) => {
	const  data = e.detail;
	// your code to process

faceImageComputed, cardImageComputed, scanResponse are CustomEvent returning data — in e.response


In your page you can keep images state by declaring variable, and update the state of these variable on the image captured event callbacks. Then you can run matching as below.

function tryMatching() {
	if(faceImage && cardImage){
		matchFaces(cardImage, faceImage, function(data){
			document.getElementById("similarityValue").innerHTML= "<h2>"+data[0].similarity+"</h2>";


This library can be used with most JS frameworks

Please note that the library expects that the application is running on a secured channel (https)


This library has been tested on the latest versions of Chrome, Edge, Firefox, and Safari. If any issues are found with some browsers, please notify us.
