I once saw an application, I think some sort of old computer emulator tool, on a smartphone, read a punch card using the camera. Which made me think, QR codes are a difficult for humans to read way to put code onto a physical sheet of paper and them pass it to a computer, just like punch cards were, when it comes to technology, there is nothing new under the sun, and on a cycle, everything old is eventually new again.
Physical, human-legible media, like punch cards
