What is "fints"

FinTS (Financial Transaction Services), formerly known as HBCI (Home Banking Computer Interface), is a bank-independent protocol for online banking, developed and used by German banks.

HBCI was originally designed by the two German banking groups Sparkasse and Volksbanken und Raiffeisenbanken and German higher-level associations as the Bundesverband deutscher Banken e.V.. The result of this effort was an open protocol specification, which is publicly available. The standardisation effort was necessary to replace the huge number of deprecated homemade software clients and servers (some of them still using BTX emulation). While IFX (Interactive Financial Exchange), OFX (Open Financial Exchange) and SET are tailored for the North American market, HBCI is designed to meet the requirements of the European market.

The FinTS-specification is publicly available on a website run by the ZKA ( Central Credit Committee).
