Penta cards issued by solarisBank require an authentication for transactions via the following two methods:


In-app notification: biometric factor e.g. using fingerprint via the mobile banking app


mobileTAN via SMS: authentication through the possession of your smartphone and the knowledge about your transactions


You will be able to choose between the two options every time you initiate the card payment. In case you didn't receive the In-App notification, please try again and choose mobileTAN via SMS.
