I wonder if it's possible to integrate a QRCode reader into delphi that uses WebCam to read. Or a bar code reader. I have no idea how to start, so I have not done anything yet!

Both simple and complex readers use keyboard or USB input to allocate data to your system.
To read QRCode
you'll usually use a 2d reader . This impute in the field with focus the string of QRCode
(or type of code 2d that is) and by default sends a line break to the end.
In programming nothing changes, it will be as if the user had typed the code and pressed enter. For example:
Reading this QRCode:
With Reader 2d, you will add 12345678901234567890
to the field with focus.
