There are many QR generators that are avialable for use. Most of these, however, are accessbile via the admin dashboard so you can create site QR codes as media files for download. This plugin also does that but goes one step further – it allows you to use shortcode to dynamically generate a QR code for the page or post being displayed.
Wolfe Candy QR Code Generator is part of the Wolfe Candy suite of plugins that all work together to make <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> site creation that much easier.
