The scanner app for Android is sitting between 50M and 100M installs: https://play.google.com/store/apps/details?id=com.google.zxing.client.android https://play.google.com/store/apps/details?id=com.google.zxi... I'm not sure about the experience on other platforms, but that particular app scans so well and easily, it'll often grab the code before you even really begin to purposefully line up the camera. Scanning the little guys has become second nature to me, at least. It is only a pity they aren't used in more novel ways, because seriously, we can do better than having one right next to a 10-character URL that I could type just as easily. Also, I recall seeing them displayed and used far more often on my last trip to Japan. I'm guessing that many of the phones there must have the scanner installed by default, or the hands-off, self-serve approach is somehow appealing to the 倭-way.
