I think you are indeed out of the loop, as this has been a punchline for several years now and is often mentioned in HN threads discussing QR Codes: http://picturesofpeoplescanningqrcodes.tumblr.com/ http://picturesofpeoplescanningqrcodes.tumblr.com/ I myself have never seen or heard of anyone actually using a QR code. However I read with great interest the HN thread two days ago about how cashless purchasing is done in China with wechat and QR codes, etc. This is all relevant to my interests as "Oh By"[1], a project I am working on, is (among other things) a replacement for QR Codes.
