Unless it has to do something with the print quality itself, can't this be achieved using a stationary phone with its camera towards a monitor displaying 3D transformed barcode images ?
Yes, possibly. But reading from the screen is quite different from reading actual barcode prints, for instance you have to deal with Moirè patterns and such. And frankly it was just a good excuse to buy an arm. Sue me! ;-)

My understanding is e-ink displays will not be suceptible to that.
I might just have given you an excuse to buy a large e-ink display/monitor :)
Haha fair play, this is exactly how things should be!
I wish I had it a decade ago when I tested phone touch screens
Very clever. This use case would never cross my mind.
