As I understand from your description, you’d like to do the next:
You have a list of cards = id’s, instead of a number you want to generate a barcode.

Please see my sample (using the next API - QR code API )

I have a list of ID’s in my collection

Using a button with onClick event, to set a src for html component - with value from database.

Here is the code:

$w.onReady(function () {
	$w("#button1").onClick(() => {
		var cardid = $w("#input1").value;
		$w("#html1").src = "https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=" + cardid;

Here is the site with live sample:
