This page has a link to this standard https://www.iso.org/standard/77404.html for rMQR barcode which looks to be a rectangular QR code like IQR so it might be the same thing... Does that mean that this barcode is now actually free to implement and use? If so then this statement needs to be adjusted

> IQR Codes have not yet been given an ISO/IEC specification, and only proprietary Denso Wave products can create or read IQR codes.

Possibly a hidden Ad Campaign?

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 (talk • contribs) 16:32, 4 July 2014

Incorrect codes for the masks

I may misunderstand but the image "QR Format Information.svg" appears to show the wrong codes for the mask patterns. The ISO IEC 18004 2015 Standard (the first I managed to find) has them in an entirely different order. MatthewGAllan (talk) 03:03, 28 January 2024 (UTC)[reply]
