I would like to know if it is possible to integrate a Qrcode reader that uses Webcam to read. Or a barcode reader. I have no idea how to start, so I haven’t done anything yet!

Both simple and more complex readers use keyboard input or usb to impute data on your system.
To read QRCode it is customary to use a 2d reader. This imputes in the focus field the QRCode(or the 2d type of code that is) and by default sends a line break at the end.
In the programming nothing changes, it will be as if the user had entered the code and pressed enter. For example:
Reading this Qrcode:
With the 2d player, you will add 12345678901234567890 in the field with focus.
