Hi QUEENB
Thank you for your request.
Everyone can buy tickets on our site, no matter which country you live in. It is important to check if your payment method is accepted, you will find the list here.
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. This pop-up window is automatically blended in by your credit card company and is not governed by the SBB.
For further queries regarding payment using your credit card, please contact your credit card company.
I wish you a nice Sunday.
Kind regards
NicolasK
