Error code DTR 3

[Jacob]

Hello, I try to book a ticket and pay with my Visa card. Then there is error code 3. Nothing works. 
I called Visa but they said everything is oke. The Visa card worked great anywhere 
Then I went to the railway station to book the ticket but there the man could not give us the “super saver” price but only the full price. What is going wrong here.

Hello @Jacob 

Thank you for your query.

Please deposit the payment method on www.sbb.ch in the login. If the error continues to appear, it is because of the credit card and therefore the bank must be contacted.

I wish you a nice day.

Kind regards,
FatimaH
