QR code generation library in javascript [closed]
I wrote a simple GPLv3 qr encoder in javascript that is local, uses HTML5 and is really fast as it is a port of an embedded C version I wrote for Atmel AVR processors.

There is a live version (which is saveable as a webapp on iOS devices) athttp://zdez.org/qrenc3.html (save to home, opens in safari so you can copy the image or use airprint)
Here is the link to the downloadable source code.
jquery-qrcode jQuery plugin also generates QR code using HTML5 canvas element or HTML table, if canvas is not supported.

$('#test').qrcode({ width: 120, height: 120, text: "https://github.com/jeromeetienne/jquery-qrcode"});
