Display-TAN

Display-TAN is a new Online and Mobile Banking method: The signature (TAN) for a money transfer or payment is generated on the bank card, after the money transfer/payment data are securely visualized to the bank customer on the bank card.

The Display-TAN app only makes sense together with a Display-TAN card. If don't have a card yet and you are for professional reasons interested to receive one, please contact us.
