    • With fingerprint or Face ID: when making payments with your card in online shops that use 3-D Secure, you as a customer will be requested – via a push message sent to your smartphone – to confirm the purchase in the PostFinance App with fingerprint or Face ID.

      With SMS code: when making payments with your card in online shops that use 3-D Secure, you as a customer will be requested to enter a security code. This code will be sent by SMS to your registered mobile phone number.
