Why would it be a wireless network to avoid? I mean, the QR code has the SSID and Password in it. For guest networks, the information is usually put up inside the areas guests go to anyway. The way it worked at my previous employer, you had the guest network SSID and password on the wall and then the QR code, so you didn't have to type them in. There was no difference in security, just convenience. As for during the presentation: surprisingly often, if you are doing workshops.
