Can I sell device time as a pay-per-minute Internet kiosk?

Selling time as a pay-per-minute Internet access kiosk is not something Kiosk Pro is designed to do. 

While the app has features that allow you to set a Browsing Time Limit as well as a list of Allowed and Restricted Domains to control where your visitors are allowed to navigate, there is no way to enable/disable these features from within the app or to tie these features to a payment.
