Running a timer on my desktop, I've just timed pulling my phone from my pocket and scanned a bar code, one handed. Including getting the phone out it took 19 seconds, without any possibility of getting it wrong.
And yes, the glasses thing is a pain, one of the disadvantages of getting old. 8-(
I just did it again - yes - 19 seconds. This time I was more leisurely, but already had my phone "home page" open. Click on apps, open menu, scan to bottom, up one, click. Point, focus, open.
Think about how much time it takes to find the app, download the app, learn the app, remember the app and use the app. My guess is 100x longer than all of the times you will ever use QR codes put together.
It's on my phone in an obvious place, and I use it a lot. I couldn't type URLs in sub 30 seconds, so it's saving me much more tham a few seconds every time.
And it's error free.
So no, that's not my problem, and I'd take it kindly if people would stopp telling me I'm wrong for finding useful something they don't agree with. Do you bother to listen to your users? Or do you just tell them they're wrong?
I think I was misinterpreted. I meant that's the problem in a general sense.
That unless QR codes are substantially quicker than manually typing a URL it will never take off. Because the fact is that people aren't typing in URLs every day.
