Hello wljt
Please do not post the same question multiple times, you are going to multiply our voluntary work.
You can find the answer here (btw, the ticket is named Swiss Half Fare Card).

→ Please note, the Swiss Half Fare Card is just a ticket; thus, the SBB Mobile app does not automatically recognize the Swiss Half Fare card yet must be set manually.
→ Furthermore, whenever you travel with e-tickets or with the Swiss Half Fare Card, you must carry your physical passport, or your driving licence, or official ID card. Copies or photos on your phone are not accepted.
Kind regards,
Roland
