Possibly a hidden Ad Campaign?[edit]

Note that reference 50 leads to http://vitreoqr.com/2014/QR_Code.html a company that CLEARLY is selling QR Codes. We should also note that everyone CAN download the iQR generator from Denso-Wave's website after registering (free): http://www.denso-wave.com/en/adcd/product/software/building/qrdraw-ad.html IMHO, this reference should be changed or removed. I'd put this as the reference instead: http://www.qrcode.com/en/codes/iqr.html — Preceding unsigned comment added by 188.250.154.18 (talkcontribs) 16:32, 4 July 2014

Possible Error in Second Image Under #Encoding[edit]

For the second image under #Encoding (https://en.wikipedia.org/wiki/File:QR_Character_Placement.svg), I'm pretty sure the words even and odd have been switched. I tried decoding it to binary by hand, and it doesn't make any sense if I use what they have, but if I change it so "dark is 0 on odd rows, 1 on even rows" I get the expected output. However, I'm not entirely sure if my suspicions are correct, and I don't have the permissions to change the image, so I've added it to the talk page. Edit: Actually, it's possible the text in the image is correct if it's assumed that the rows start at 0 from the bottom. It would most likely be helpful to label rows on the image.

New image?[edit]

Totally not a Rickroll QR code

Can we make this the new infobox image? Please? Pretty please? Even temporarily, like on April 1? --Diriector_Doc├─────┤TalkContribs 22:23, 4 March 2021 (UTC)[]
