FinTS


FinTS, formerly known as HBCI, 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 Association of German Banks. 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.
While IFX, OFX 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.

Features

HBCI has been superseded by its successor FinTS, and as of 2011, 2000 financial institutions in Germany are supporting FinTS.

Versions

HBCI 2.2 PIN/TAN

HBCI 2.2 PIN/TAN is an extension to HBCI that added a security method based on PINs and TANs, which had already been in use with BTX and web banking.

FinTS 3.0

For version 3.0, which formally introduced the PIN/TAN method, the specification was renamed to FinTS, whereas the original DSA- and RSA-based security method retained the name HBCI.

FinTS 4.0

In version 4.0, the basic message syntax was switched over to XML. Further, the number of roundtrips necessary was reduced, allowing asynchronous communication for simple transaction dialogues.
