What is the DSFinV‑K?

DSFinV‑K is the description of an interface for data export from electronic record systems for data transfer. This is required for audits and Kassen-Nachschau inspections. 

What do the changes to DSFinV‑K 2.3 entail?

Here we have compiled brief explanations of the most important changes for you.

Serial number

Previously, the POS serial number was stored in the technical security system (TSS). With DSFinV‑K 2.3, this must now also be stored in the DSFinV‑K. Note: For technical reasons, neither slashes (“/”) nor underscores (“_”) may be used in the POS serial number. 


DSFinV‑K 2.3 contains many clarifications on scenarios concerning the correct integration of the interface.

English translation

The DSFinV‑K 2.3 is also available as an English translation. The translation is not legally binding.

Application regulation

DSFinV‑K 2.3 applies to records made on or after July 1, 2022. Version 2.3 can also be applied before that.
