QR Tips is a Wordpress plugin that generates a QR code for sending a tip via MultiSafepay.
Download as zip and install in the 'new plugin' screen.
Go to Settings > QR Tips Settings. Add your MultiSafepay API key, enter a title and amount.
Next you can add the shortcode [qr_tips] to any page on your site.
This is my first plugin so please leave any feedback you have!
