Hello dthardin
Thank you for your message.
What did you buy exactly? A GA travel card of a half fare card, or normal tickets? If you bought a travelcard you have the possibility to show your pass via de SBB Mobile App. For do that you need a swisspass login.
In order to help you in the best way, I recommend you to call our contact center: 0848 44 66 88 (CHF 0.08/min.).
On the following link you can find many information regarding the swisspass and the travelcards.
I wish you a nice day.
Kind regards, GiorgiaB
