The WordPress Plugin 2D Barcodes creates automatically a 2D-Barcode to every post you have produced. It will use the TagSOLUTE (http://www.tagsolute.de) API to create the 2D Barcodes. All you need is a DevKey or an API Key which can be created at http://www.tagsolute.de/profil
Now it is very easy to see your WordPress Blog on a mobile device. Just scan the code with your mobile phone, an view the post on your mobile device. In each post you can set a Code and the 2D Barcode picture will not be displayed in this post. Have fun! If you are browsing the WordPress Blog with a mobile device, the 2D Barcodes will not appear.
If you need a mobil Plugin for WordPress we suggest the plugin “WordPress PDA & iPhone”. https://wordpress.org/extend/plugins/wp-pda/
