Hello Amit Jena
These cards are currently sold out, but you could buy a Saver Day Pass, full price if you don’t have a Half Fare Card. You can find a link to an area map of validity here:

Stanserhorn is included, but they have a limited capacity and you should except very long waiting times if the weather is good.
Kind Regards
Daniel
