This plug-in allows you to generate QR codes (in BMP and PNG files) from your publications, specifying various options such as the size of the points in the image, margins, text and background color, level of error correction, etc. The plug-in allows you to generate QR codes using plain text and of course you can use the text with the appropriate format to specify information for special QR codes for emails, SMS, VCard, geolocation points, etc.
