Help needed with ZKTeco controller to integrate it in a JAVA program

I am a student and I am trying to integrate a ZKTeco controller (C3-400 with RFID reader KR600) to my JAVA program for my study project.

I have been successful connecting my program to the access controller and manipulate it, however, the real-time events are not being triggered and I don't know how to do it.

I want my program to:

- Detect in real-time when someone is passing the card through the reader (in the background)

- Get the number of the card

- Get the ID of the reader (or any unique information about the reader).

The SDK and documentation and available on their website with C#.
