Question

WiFi

I have such a question, since I have never come across this. I need to practically need to set up a standard free wifi connection and to give the user free wifi after knocking down a code that should come via sms or other action. How to implement it, where to look and where to dig

There are ready-made solutions like www.hot-wifi.ru
But you can do it yourself - you will need a brain, knowledge of routing and the intricacies of setting up hot-spot in a specific router model, also a server that will handle authorization - send SMS, receive codes, etc. If you do it yourself, you can integrate it with the cash system - when the client receives the code after payment and it is valid for a limited time.

The main principle of hot-spot is that before authorization only the authorization service is available and when you try to open other sites it throws authorization - the Internet is blocked by a firewall. After authorization, the firewall unblocks the authorized client and any sites and other IP connections are available to him.
