HBCI is only made available by Targobank for customers who use the mTAN(smsTAN) procedure. 

Here are further hints from Targobank, Targobank is working on solutions:

  •  When displaying credit card transactions (HKKAZ), the sign of the transaction amounts may be reversed.
  •  In some cases, for example, the login does not work for some solo credit cards for private customers.
  • The turnover history for current and call money accounts can only be called up in the long term via the camt format (HKCAZ).
