Yes, both. I have made QR codes for paper and have also scanned them 
from my desktop and from my phone (just like Google Pay passes). I used 
LibreOffice Writer to place my WiFi QR codes alongside identifying 
information on a single page for printing. Smart phones seem to have no 
problem reading them from paper or screens.

QR codes are designed to work in dirty industrial environments. Another 
nice trick is to use "qrencode -l h" to encode a high level of 
redundancy so that ~30% of the QR code can be overwritten with a logo or 
other artwork such as a WiFi symbol.

Kind regards,
