This plugin is a QR Code (Quick Response) generator for mobile tagging. It allows you to create one of the ever-popular QR Codes anywhere on a page/post or in a text widget. A simple shortcode defaults to generating the 2d code for the current page/post.
Plus, attributes allow you to set the: size, color, url (or email, text, phone number, vcard, sms, etc.), tooltip, image format (png or jpg), and error correction level … along with an option to use a shortened url.
More details are available under Installation (above) and at Dashboard->WCS-QR-Code (after activation).
