So you just take a photo of anyone's QR code? I'm not sure the hidden SSID achieves anything, that is presumably plaintext in the wi-fi transmission?

That QR code would only be displayed for a short time, and mostly only people sitting directly behind you could snap the picture.

It's not airtight, but better than the system it would be replacing.

The hidden SSID stops the users' WiFi list being full of random, password protected SSIDs when they just want to connect to the open portal WiFi.
