• Manor, TX put codes on lots of public property.  22-year-old CIO.
  • e.g. QR code on the backstop of a baseball field that brings up the schedule
  • Ann Arbor (MI) District Library put QR codes on their summer reading game posters.


  • Different colors of code for different types of information
  • Are we allowed to put QR code stickers around the city, or is that illegal?
  • City may need to eventually give its blessing, much like the WalkRaleigh project last year.
  • QR code leads to a redirect page, so if the original destination goes down it can be relinked.
  • Maybe the intermediary is Triangle Wiki?  Also provides publicity for TriangleWiki
  • QR code generator that's colorized by type.  Open source the creation of the QR tags.
  • Plugin for LocalWiki that generates a QR code for the page.
  • Doesn't have to be a printed sticker--could also just be embedded on another page.  Scanning the tag with your phone will open the link in your browser.
  • How much does the city need to be involved?  Have the city adopt a common protocol that defines how to generate the code, where they can be.
  • If it's easy to produce a QR code, how do we prevent someone from printing bogus ones that link elsewhere?


  • Wales, UK is doing this in partnership with Wikipedia.  QR codes around the city linking to historical information.
  • Some companies, e.g. provide re-linkable QR codes.

How to do it

  1. TriangleWiki plugin that generates a QR code for every page
  2. Find a graphic designer to design a cool-looking "sticker" that contains the QR code, the triangle wiki logo, maybe the name of the page
  3. Talk with WalkRaleigh people--how to print the signs, reuse their existing code that open sources their generation
  4. Find some seed money to print out a first batch of codes.  Maybe use public art installations?
  5. Volunteers install these.
  6. People see them, scan them, learn more about Triangle Wiki, get more involved in the community
  7. Peace descends upon the planet.  We are all knighted.
