Is it possible to open the camera on a phone with a barcode scanner on the site?

Question

Barcodes

Hello, I need to make an application for couriers with a barcode scanner.
That is, an order came, clicked near each item - scan the sh-k, the camera opened, the person scanned the sh-k, the system gave information - the product was found (correct) or not found (the sh-k was not the right one).
Actually, the only question is, is it possible and how to open the camera on the phone and recognize sh-k? It is clear with android and ios, but not with web development..

Answer 1

The maximum that can be done is to insert an input like this:
Clicking on it on mobile devices will call the camera, and not the file selection, as usual. Further it is possible on event onchange for this input to hang up sending of the form on the server. But code recognition and all subsequent processing will have to be done on the server. Or write a full-fledged Android application.
