[Lab] QR / Registration / ??? Concept

What's the big problem with a network? It's the easiest, most reliable way
to do it. I've never had problems with networks that are set up correctly.
By default, they should be robust and reliable.

There are many ways to implement what you propose... but I think the
easiest would be a simple app scanning QR codes, with a small LCD screen
that shows what the camera is seeing (from the scanner's point of view,
like with barcode scanner apps on smartphones). This could be run from a
small Linux box, even, perhaps, a Raspberry Pi. Then have one (or two)
boxes sitting where the organizers are, with screens, simply monitoring
progress as people check in. That way they can go to any of the available
kiosks, they scan their QR code, it looks them up and spits out the agenda
via laser printer... done. Easy. Simple.

Peace, Love, Empathy
