There are ways to do that. They are external libraries which convert a file input into something that asks for camera access. You take a picture of the QR Code and then all the data from the QR Code goes into that one field. It does not get split into individual fields. At least none of the libraries I found did that. If you find one that works, we can see about incorporating it with Gravity Forms.
Incorporating something like that is more complicated than the approach I recommended earlier.
p.s. Zoho CRM has a field for this already built in:
GoCanvas does as well:
