Quoted from paul_8788:Plus, static QR code is worse for player security.
"Look, I printed off a QR code so I don't have to use my phone!".
Three beers later:
"Fuck, I lost my card!"
Now some dingus has your card. Maybe not a big issue in the scheme of things, but a dynamic security QR code that the pin generates and displays on the screen has other benefits, not just eliminating a QR reader from each pin.
You guys are over thinking this - it's not bank level security - it's a f'n arcade game
Quoted from Dent00:One thing about this entire effort that makes it a little bit fruitless in my opinion is the fact that you have to load an app on your phone to read the QR code on the machine you are playing. So what happens if you don't have a phone that will read a QR code? That is me... I have a phone that makes phone calls and sends text messages just fine, but I never turn on the data... In fact, I keep the "data" turned off to avoid those charges. The phone even takes great Hires photographs. It's a 4G phone by the way and AT&T keeps sending me messages and junk mail that I have to upgrade to a 5G phone to be able to continue to use data. Since I never use any data, I just ignore those messages. I don't see why the machine cannot just connect to wifi at the location where it is located so that I don't have to pay for the data transmission, to be honest.
As said a million times, for you non smart phone guys, print out the QR code and carry it in your wallet - or turn on your data most likely you are already paying for data in your phone plan and just not using it.
