If they check that, and/or geofence, it would still make sense to collect all the QR codes here, to save others from having to wander the airport scavenging for QR codes during their layovers.
And dang, I'll be in MUC on the 14th, and then only on the 25th :/ I'll try to walk around on the 14th though, maybe they'll put up the QR code early... although, knowing the rest of their IT, they'll probably be a few days late :P
