Other alternatives:

• QRPedia - only works on *.wikipedia.org domains
• https://qrcode-generator.toolforge.org/ - this partially solves what the original wish was. Based on further reading on the comments, I think some wanted this tool to be more integrated to the Wikimedia projects, either as a button, as a link, or something else
• bit.ly's QR code - an example of 3rd party QR, but we don't want the QR to go to 3rd party links first, because we don't know how long it would stay up and/or if it will be injected by spam/ads. (this example is not the one I mentioned on the original wish)
• Microsoft Edge's built in QR generator. It's available on the browser itself (to the right of the address bar), and it's quite nice feature, I should say. But, the limitation being it's browser exclusive perk.

Technical consideration, provide some settings to users, such as:

• Option for Permalink vs Nice url (the regular link), including section marker ([[Link#Section])
• Able to turn into QR any wikiprojects link, including in various namespace, special pages, w.wiki links., and links with a lot of parameters
• (optional) Project logo in the center of the QR code, doesn't need to be the localized logo, a generic one would be fine

There's also the QRLite extension which can be used to embed QR codes in wiki pages.

OK, I just found out about this several minutes ago:

I've started some notes about the various existing projects etc.: https://etherpad.wikimedia.org/p/qr-share — please add anything that's relevant.

Added some notes.

I've moved most of the etherpad notes to https://www.mediawiki.org/wiki/QR_Codes as a general summary of the whole topic of QR Codes.

I guess this task can serve as the epic. I'll add the others as subtasks.

We are aiming to deploy this to all wikis on February 1, 2024. It adds a link to download a QR code for the current page in the "Tools" menu, and adds a new Special:QrCode page.
