jsQR VS qr-scanner

I used https://github.com/cozmo/jsQR in production for years. Never had any problems, before all smartphones had built in QR readers, most of our users would use it primarily to interact with our product. Works for iOS and Android. To my knowledge does not use ZXing and is Apache Licensed.

Convert the image to ImageDataand use a library like this to read it: https://github.com/cozmo/jsQR

I've had a good experience using https://github.com/nimiq/qr-scanner for QR codes too.

This paper (https://link.springer.com/chapter/10.1007/978-3-030-57058-3_...) might help and is available on github (https://github.com/nimiq/qr-scanner).

I want to integrate qr-scanner to my project. This library is capable of decoding QR-Codes by utilizing the camera. It just needs the reference to a html-video-element and then renders the webcam-stream and optionally some indicators of a QR-code being found to this element.

Have you tried something like this: https://nimiq.github.io/qr-scanner/demo/

If you can copy the picture into paint and cut out the QR code then plug it into a QR code reader website like this one which is open-source and isn't cluttered with ads (which I don't see anyways because I use uBlock Origin, a superior adblocker available for chrome and firefox), you'll get the following data

Here is the library I used to read the codes; https://github.com/nimiq/qr-scanner

The scanning function utilises a JavaScript qr code reader to parse the information from the qr-code to the server.
