|

>. It allow you to easily add qrcode to your webpages. It is standalone, less than 4k after minify+gzip, no image download. It doesnt rely on external services which go on and off, or add latency while loading. It is based on a <a href='http://www.d-project.com/qrcode/index.html'>library</a> which build qrcode in various language. <a href='http://jeromeetienne.github.com/jquery-qrcode'>jquery.qrcode.js</a> wraps it to make it easy to include in your own code.</p
