Hello @Alns
With the Saver Day Pass you can travel throughout Switzerland for a day on all routes in the GA area. You do not need to have any discount cards like the Swiss Half Fare Card. In the step ticket options of your order, you will be asked to enter your discounds. You can choose "no discount"You will find all information as well as the validity map on our website.
I wish you an awesome time in Switzerland.
Kind regards, RahelW
