This plugin is a QR Code (Quick Response) generator for mobile tagging. It allows you to create one of the ever-popular QR Code images 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, tooltip, image format (png or jpg), and error correction level … along with an option to use a shortened url. The url attribute can be utilized instead as an email address, plain text, phone number, vcard, sms, etc.

Shortcode Usage Information
Upon activation of this plug-in, you'll have access to a new shortcode that generates QR Code images. In its default usage, a QR Code is generated for the current page/post. Additionally, you can use the shortcode anywhere on a page/post or in a text widget.
Basic Usage Syntax:
[wcs_qr_code url='now is the time' size='128' color='darkblue']
- url is the content for the qr code image (defaults to the current page/post url)
– more on this below
- size is square image's size in pixels (default is '100')
- color can be a 6-digit hex color value or an HTML color name (default is 'black')
- ecl is the error correction level (default is 'L|4')
– more on this below
- shorten is a toggle for shortening the url (default is 'false')
- format is the image format (PNG or JPG) (default is 'png')
- tooltip is the image's tooltip text (default is none)
Essentially, the ECL code consists of two components: (1) the error correction level (L, M, Q, or H), and (2) the white border row/column width (1 – 40 rows, not pixels).
If omitted, the URL defaults to the current page/post url. You can also use any valid url or text (within the character limitation of the selected ECL attribute value).
When using an email address, a standard format is expected. For example email@example.com should be implemented as mailto:firstname.lastname@example.org.
Telephone numbers also have a standardized format. For example, 212-555-1212 should be implemented as tel:+12125551212.
An SMS link is encoded in a fashion similar to an email address. For example, a link to the number 12345 should be implemented as sms:12345.
These and many other possibilities are explained in detail here.
