Michael,
There's a great article in this month's Dime magazine (February/March
2006 in Japanese) about QR codes. http://www.digital-dime.com/ In the
printed magazine its on page 158-160. Although it's about the Japanese
market, it give a very interesting overview and details about the
capabilities and limitations of these codes.
For clarification, I believe a QR or "Quick Response" code, is just the
name given to 2D "2-dimensional" barcodes by Omron. So I believe that
these are one and the same thing technically (but please feel free to
correct me if I'm wrong).
