Here’s a simple way how to do it.
Our iWifi Timer software is built to control and sell Wi-Fi network access to users. It is perfect for places with a high frequency of users.
This is how it works for end users:
Upon connection, the system greets the user with a customized welcome portal in their web browser. The user is then able to select internet access free of charge for time period configured by the administrator, and once free period is consumed, an additional time period (hour, day, week, month…) can be purchased. Supported models of payment include vouchers on POS terminals, credit cards, and PayPal account.
Extending the network access time requires a passcode which the user obtains by payment and enters it when prompted.
