What specific examples do you guys use QR codes for on websites?<p>How well does it work (not in terms of recognition, but traffic generation, etc)?<p>I am looking for a use, but always come up with easier solutions that do not involved barcodes and image recognition on smartphones.
it's great<p>another way to get a qr code in just one line:

Looks like it uses canvas to draw the qr. Using something like <a href="http://raphaeljs.com/" rel="nofollow">http://raphaeljs.com/</a> would have made it even better for backwards compatibility. Awesome job though!
Note that the qrcode.js part of this is<p><pre><code> // QRCode for JavaScript

Here's the related QR project(s). (Note the implementations in other languages.)<p><a href="http://www.d-project.com/qrcode/index.html" rel="nofollow">http://www.d-project.com/qrcode/index.html</a><p>I forget (if I ever knew) whether this has any connection with the originators of QR code:<p><a href="http://en.wikipedia.org/wiki/Denso" rel="nofollow">http://en.wikipedia.org/wiki/Denso</a>
It would be more convenient if it automatically wrote the canvas out to a Base64 encoded png, imo. Makes for easy saving because I can then drag it to the desktop.
