Stick one on a physical object encoding a link to a page that can be configured to 301 to arbitrary URLs (e.g. https://www.noisebridge.net/qr/07A72C23A7), and you get a system for hardlinking physical objects into cyberspace.
You can embed a QR code for any page on the wiki, of its own URL, by including this snippet on the page:
- QR code embed snippet:
{{#qrlite:{{fullurl:{{FULLPAGENAME}}#section-fragment}}|format=png|size=5|margin=0}}, prefix with a <br> to set it on its own line.
- Include the text of the link,
<br>{{fullurl:{{FULLPAGENAME}}}}, in text near the image, for the others' clarity when browsing & for printing.
