If you can't write up a full-featured QR code scanner from scratch in 15 seconds, can you really call yourself a programmer?

On a more serious note, though, I wouldn't be much impressed with QR code menus. I usually have my 4G off, I don't trust random wifi networks, and I don't like smartphones as a form factor for any text over 500 characters.

HN is so ironic, they complain and criticize everything but fail to understand QR code. Are they actually a programmer or only acting like it. India already have UPI implementation while in the USA they need apple to save their useless banking system and still fail to move on with tech.

It's weird that people hate QR codes so much. Perhaps is it phenomenon only in the US? It's just a information encoded as a square, not something like Skynet.
