I want to open paid wi-fi, I need to find an analogue of hotspotsystem billing, are there any with source code?

Question

WiFi

Good day.
Please tell me, as a person who is friendly with IT, but far from System Administration, about how such a system can be organized on the beach with minimal blood loss:
1. A person connects to a publicly available WiFi access point.
2. A person does not have access to the Internet, on any site he is asked to log in.
3. A person has registered and sees the tariff selection window, and after that he pays through UnitiPay or personally gives me money and gets N time to surf the Internet.
4. A person sits N time on the Internet and receives a message that it needs to be extended.
5. And that's it
And now the question?
How to work with WiFi distribution, and disable one or another access to the Internet?
Is there a ready source?
Thanks for answers.

Answer 1

The ready hotspot is already in Mikrotik, along with Radius authorization.
But the logic of billing and payment will have to be done by yourself, things are not really handed out (even for money). :)

Answer 2

6. ...and it's cool to get hooked on illegal business - because you can only provide a provider with a license. And you will also need SORM - because according to the "Yarovaya package" you are obliged to store a lot of things. Because tomorrow Vasya will post a CPU from your hotspot, Petya will write "#krymnenash", and Kolya will send a false message about the mining of the neighboring shopping center...
