QR Codes Local
By adding around any text or url in article or virtuemart product description a QR image is created and displayed instead.
This plugin and the corresponding module do not call a script on an external site to create the QR codes or external scripts that then call another site to create the QR code. All codes are created locally on your server and cached for later use.
The Module QR Codes Local 2.5 must be installed for this plugin to work.
