Hello Nanoosuck71
Your question is about the Swiss Half Fare Card and the Swiss Family Card.
As reduction types, you can choose the ‘Half Fare Card’ for the adults, and ‘Junior Card’ for the kids.
There are certain ticket types, for example when using the Saver Day Pass or the Day Pass for the Half Fare Card, that require the splitting of the journey.
Be careful when trusting ChatGPT for ticket questions. It is not a trustful and legal source of information for train ticketing. Daily, passengers are caught during ticket check with the wrong ticket because they have been trusting ChatGPT.
Kind regards,
Roland
