Not going to be a big problem for most of us. But as we know Google Glass uses QR codes to setup and can use codes to connect to wifi networks. QR Codes: simplifying connectivity, sometimes even malicious ones. Google has since issued a fix.

Google has experience in this field having had a QR code based temporary login service in the past.

Google Glass uses QR code during setup to sync.
