In the current version of Outbank you can find the 'Baaderbank Unterschleißheim' in the bank search when you search for Oskar. The Oskar accounts are probably also managed under this access.
To set up the bank access you need the access data for "HBCI +" or "FinTS PIN / TAN" from Baader Bank:
- User identification
- Banking PIN
If in doubt, please inquire directly at Baader Bank for the access data for the HBCI system.
