Do I have to get 2D barcodes tattooed to my finger tips or will my fingers be born that way? Or is that just a side issue?

Can it come with some hand sanitizer so I won’t get dataviz germs if I interact with someone else’s augmented reality? You know, in case they picked their earballs toegaps or nose before visualizing stuff?

I prefer to wear my nails long, but not effeminately so — its a cultural thing. Will this interfere with my data sets in any way, perhaps by scuffing or scratching the data in some fashion?

Will the data leave any stains or cause any skin sores or something if it’s of a particular variety or representative of specific kinds of things? Pollution for example? Or toxic spills, crime, solar flares — that sort of thing?
