QR Codes Debate

Greater use of QR is not a good thing, it's an attack vector actually

Any technical reason not to use a QR code?

Am I the only one that doesn't like QR codes? Just use a URL instead.1) You need a smartphone to scan them. People without a phone handy can't scan them, so if you see an ad somewhere, and want to check it out later you can't just remember the URL. For example, you might not want to take out your fancy new superphone in the subway.2) It's slow. If you have a current top-model, it might be tolerable, but it's easier to just type in a URL on many phones.3) It only works ok in the best ca

Why do you deal with QR codes so much?

No, they aren't if you create a nice QR code for people to scan.

The better question is why are they using QR codes??

Yes, most of the time qrcode is seen as a gimmick, ie you might as well write the url instead of downloading a qr reader app.Here is my hope for making good use of it.

Don't overestimate the general audience. You can scan QR codes with every modern camera app, but if you don't know you can, you'll have to wait for someone to tell you. It's been months since I last saw a QR code and that was just because of a TOTP setup, I doubt most people use them in their daily lives. Many apps using them like to pretend you need to download their app to scan them as well.My biggest issue, outside of the usual terrible websites these codes link to, is

No one's using QR codes. See: http://picturesofpeoplescanningqrcodes.tumblr.com/

This would be cool – the problem, 99.999% (source: I made it up) of people just know to open the camera app to scan a QR code. So if this is displayed publicly, nobody would know how to scan it without going to another website anyway, which I feel defeats the purpose. Very interesting implementation though!
