I've built a few systems for low-cost airlines in South America. There shouldn't be a lot of difference with bigger airlines around the world.
The boarding software usually checks that:
- The boarding pass is valid (checksum)
- The flight state is correct e.g. 'boarding' and 'open'
- The passenger did check-in
- The passenger haven't boarded yet
More advanced implementations can match the gate with the flight, this is optional.
The beep usually is a response from the reader indicating that the code has been read successfully.
The result of the operation is displayed in a screen and the attendant has to read it and act accordingly.
