Hello Moodoahues95
You are talking about the Swiss Half Fare Card.
It cannot be seen in the SBB Mobile App if it wasn’t purchased as a registered user.
You cannot import a ticket into the SBB Mobile App that was purchased as a guest.
Simply store your Swiss Travel Pass as PDF document on your phone, or take a screenshot of the QR-Code and store it in your image gallery.
Whenever you travel with your Swiss Travel Pass, you must carry your physical ID or ID card with you. Paper copies or photos of it on smartphones are not accepted.
Kind regards,
Roland
