How does OnlineÜberweisen work?

For OnlineÜberweisen, at the checkout of your merchant an OnlineÜberweisen form is displayed. In this form you select your bank by entering your BLZ or BIC or the name of your bank. You will then be asked to enter your bank login details. In the background, an online transfer will then be made to your account and you will be asked for the appropriate TAN to confirm the transfer. Your merchant will then be informed of the transaction.
