I scanned the QR code on the 'old badge' and it said "spiral gestalt spiral gestalt spiral gestalt spiral gestalt"
I scanned the The 'Nuclear Device Project' and it said "mainserv\public\the_modular_site_project\"
I scanned the Emily Ross' badge qr code and it said
"Emily Sharon Ross
Assistant Researcher
Lvl 2
Code: 55.678741-4.065784"

Is there any more QR codes?

I'm pretty sure the "spiral gestalt" is a reference to the 'strange note' and the code in Emily's badge is the coordinates to a store called 'Emily Ross Furnishing'. But what about the 'Nuclear Device Project'?
