Swiss Half Fare Card can use buy the supersaver ticket ?

Hi all
next week I’m visiting switzerland and I have already purchased a Swiss Half Fare Card from a distributor in my country.

But I need to know Swiss Half Fare Card (tourist version) can use buy the supersaver ticket ?

Because Some people in my country say Swiss Half Fare Card can’t buy supersaver ticket.

Yes, the Swiss Half Fare Card allows the purchase of any tickets that are available at half fare including Supersaver tickets.

Kind regards,
Roland
