What Is a TAN
A TAN (transaction number) is a one-time password (OTP) used in Internetbanking to verify transactions.
How Does smsTAN Verification Work
The smsTAN Verification is a two-way authorization procedure. When you want to place an order you receive your TAN only if required via SMS directly to your mobile phone. . This TAN is valid only for a few minutes and just for this transfer. The transaction will be completed after entering the TAN into the specified field.
Why Is smsTAN Verification Safer than Paper TAN Verification
You will only receive your TANs if required. A second device, independent from the PC is used for the verification of the TAN. This method offers a very high level of protection against phishing and malware.
The transmitted TAN in the SMS is additionally always inseparably linked to your order. It cannot be used for other transactions. A third party cannot manipulate the mobile phone number used for the SMS transmission because it is stored directly in the highly secure banking system of DenizBank AG.
Your order´s data is also displayed in the TAN SMS. Before entering the TAN, compare the data displayed in the SMS with the data entered in Internetbanking. Only if all data match, you should execute the transaction.
