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.

Type in your money transfer data: destination account and amount 4. Press "Get TAN" 5. Turn the Display-TAN card on, via OK button 6. Wait some seconds for the BLE transmission to the card 7. Confirm the destination account via OK button on the card 8. Confirm the amount via OK button on the card 9. The TAN will be generated on the card and will be send via BLE to the smartphone 10.
