QR Code Generator creates scannable QR codes for your WordPress content. Each post, page, or WooCommerce product gets a compact short URL (<code>/go/{base36}</code>) that 301-redirects to the original permalink.
Key Features:
<ul>
<li>Pure PHP QR code engine — no external APIs, no JavaScript rendering</li>
<li>Short URLs via <code>/go/{base36}</code> with permanent 301 redirects</li>
<li>Works with posts, pages, and WooCommerce products</li>
<li>Customizable pixel size, quiet zone, and colours</li>
<li>One-click generate, download, and copy from the editor sidebar</li>
<li>Lightweight — only requires the PHP GD extension</li>
<li>ISO/IEC 18004 compliant QR encoding</li>
</ul>
How It Works:
<ol>
<li>Edit any post, page, or product</li>
<li>Find the “QR Code” meta box in the sidebar</li>
<li>Click “Generate QR Code”</li>
<li>Download the PNG or copy the short URL</li>
</ol>

Notice: I’ve have since stopped development of this plugin as I feel that the state of URL Shortening services seems to have converged and there isn’t much more progress I have in the pipeline for this plugin.
<a href="http://wiki.fusedthought.com/docs/url-shortener-wordpress-plugin" title="URL Shortener" rel="nofollow ugc">URL Shortener</a> allows you to generate shortlinks for post/pages using URL Shorteners (e.g. Bit.ly, Su.pr and many others), with a few additional features.
Please check your settings when upgrading to Version 4.0 from previous versions prior to it.
What’s New with 4.0
<ul>
<li>QR Code Support (using Google Chart API)</li>
<li>Additional Shorteners (Goo.gl, dlvr.it, yourls) </li>
<li>Nice ID links with QR Code (i.e. http://your_site/123.qr)</li>
<li>Version 4.0 features completely refactored code once again. Now includes classes which allows developers to easily extend the plugin.</li>
</ul>

<ul>
<li>Automatic generation of a Short URL/Shortlinks</li>

<li>Relatively extensive shortlink support</li>
<li>Action Hooks available for other plugins to utilize generated shortlinks (From Ver 3.0 Onwards)</li>
<li>Nice ID links – http://your_site/123 instead of http://your_site/index.php?p=123</li>
<li>Shortcode support (Ver 3.1): Place [shortlink] in your article where you want to display the shortened url.</li>
