    Have any of you deep-in-the-craft Makers ever seen the algorithm by which QR Code is *de*coded (dot_pattern -> text)?

    I’ve been hunting for over a year now, and the closest i’ve come is “there is a function for that written in java for a project that’s now dead on this link that is broken …”

    It’s said that this algorithm has been openly released (from Japanese industry-land) …but where? behind some pay-for-ACTA-IEEE wall, or what?

    Thank’ee!

      Check out the QR Code library:
      http://qrcode.sourceforge.jp/

      and the Japanese one that you mentioned (which is in Japanese) is here:

        Thank you Sir! That qrcode.sourceforge.jp link has considerably more than I had seen elsewhere.

  2. Thanks for posting this innovative use of QR codes..
