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 (talk • contribs) 16:32, 4 July 2014
→ The vitreoqr.com domain is inactive. I believe the link should be removed and changed. Internetyev (talk) 18:36, 31 January 2025 (UTC)

Add a new bullet point to the "Standards" section to reflect a new version of the ISO/IEC 18004 standard released in 2024:
August 2024 - ISO/IEC 18004:2024 Information technology — Automatic identification and data capture techniques — QR code bar code symbology specification Optimizes encoding efficiency, improves error correction, and refines structured append functionality.
Note: The description above was generated using AI analysis to compare the two versions of the standard.

Suggestion for External Links Section
[edit]Hello!
I’d like to suggest adding a new link to the "External links" section of this article. The website provides a free and easy-to-use tool for generating QR codes specifically for payments (e.g. PayPal, Cash App, Venmo), which could be useful for readers interested in applying QR codes in real-world payment contexts.
Proposed link: QR Code Generator for Payment – OnlineQRCode.com
It’s a free, no-registration-needed generator focused on mobile payment applications. Thanks for considering! Claudialopra (talk 10:57, 1 April 2025 (UTC)
- The article would not benefit from promoting this business, and that's all a link like this would be doing. The specific URL you added provides QR coes that embed a tracker into their generated codes by default and as far as I can tell when trying does indeed require signing up. The root domain itself (which you did not link to) provides the ability to create a simple QR code, but also appears to require signing up to download them. Promotional links like this have no place on this or any other Wikipedia article. - Aoidh (talk) 16:14, 1 April 2025 (UTC)
Header image standards non-conformance
[edit]Please see the question posted here: https://stackoverflow.com/questions/79786399/does-this-code-indicate-a-mistake-in-wikipedias-example-on-the-qr-code-page
It appears that the image at the top of this page may not technically be a valid QR code. In that case, it should probably be updated in the name of accuracy. Bismurphy (talk) 14:24, 13 October 2025 (UTC)
- I have uploaded a modified file here:  Derived from https://commons.wikimedia.org/wiki/File:QR_code_for_mobile_English_Wikipedia.svg with correction for Remainder bits. Modifications done by hand with manual modifying of SVG text format. 
- I am not sure what the best path for this change is - perhaps it would be ideal to replace the existing file? I do not have permissions to do so, unfortunately. Bismurphy (talk) 16:02, 15 October 2025 (UTC)
