it's kind of crazy to think about how modern public transports are moving to QR code validation for some kind of tickets, but like, with the user as the source and the terminal has a camera and you're supposed to shove the qr code there???

like, not only the qr codes themselves feel kind of an archaic solution, but also, WHAT DO YOU MEAN THE TERMINAL IS THE CONSUMER 💀

I know cameras are cheap nowadays, but this is such a janky solution in so many ways

if qr codes really are the way to go, wouldn't it make more sense for the terminal to be the producer and always have newly generated qr code on a display you can scan using your phone? just like we already do with payments
