Hello @loulopez83
It is not possible to purchase travelcards over the SBB Mobile application. Please use the link above.
Does your credit card use «3-D Secure Code» as a security element? If so, a page will appear during the payment process requesting identification (password, SMS, fingerprint, Face ID or Transactions App). This will clearly identify you as the cardholder. If this service is not offered by your credit card company, the card will automatically be rejected on our website. We cannot determine the exact reason why your credit card was declined.
If it is not possible to use your payment card for bookings on SBB.ch. We recommend that you use a different payment card or that you purchase your tickets at any railway station ticket office after your arrival in Switzerland. The Swiss Half Fare Card can be used immediately. I wish you an unforgettable time in Switzerland
Regards, RahelW
