Frequently Asked Questions

General​

To whom does the Cash Security Ordinance apply?

The manufacturers of cash registers, cash register systems and software solutions for recording business transactions, such as accounting programs, are responsible for the legally compliant implementation of the KassenSichV - efsta offers the efsta EFR middleware to ensure compliance with the law: Compliance as a Service. Taxable entrepreneurs are also bound by the KassenSichV and, in addition to the legally compliant use of the selected cash register, must also comply with the reporting obligation for cash registers from January 1, 2025!

Who is affected by the reporting obligation?

From January 1, 2025, all taxable persons are required to transmit the electronic recording systems - cash registers - and the TSE(s) they use to the authorities. The taxable person is responsible for reporting the required cash register data. All electronic recording systems within the meaning of Section 1 (1) sentence 1 KassenSichV acquired before July 1, 2025 must be recorded by July 31, 2025 at the latest - including the TSE(s) used

How can be recorded:

  • Electronic data transmission will be possible from January 1, 2025 via "My ELSTER" and the ERiC interface.
  • All systems of a business premises must be reported uniformly in an XML data file.
How can I change the company's legal name?
  • Carry out the daily closing and the TSE export.
  • Check whether the recorder is online and all transactions are available in the cloud.
  • Uninstall EFR and archive/delete the EFR folder under C:\ProgramData\EFR
  • Deactivate EFR and all old companies in the efsta portal
  • Create the new company in the portal
  • Reinstall EFR (download here: http://public.efsta.net/efr/ )
  • Call with localhost:5618 - Configure profile page (ID,,...)
    • Optional: for Cloud TSE - order a new fiscal unit (the assignment is made via the “automatic CloudTSE assignment” by the efsta cloud if the TSE was obtained via efsta; for self-purchased TSEs it must be configured manually).
  • Start the checkout process

Please inform your Partner Manager when everything is done so that billing can be switched to the new company and a special termination of the TSE can be initiated.

TSE​

KassenSichV​

What does the KassenSichV mean?

The Cash Register Security Ordinance (KassensichV) is an ordinance of the Federal Ministry of Finance (BMF) that prescribes new mandatory standards for the prevention of manipulation of cash registers. This ordinance defines the technical specifications for electronic recording and security systems, such as cash register or ERP systems. From January 1, 2020, all cash registers in Germany must be equipped with an anti-tampering device, known as a technical security device (TSE).

What is regulated in the KassenSichV?

The aim of the KassensichV is to be able to detect subsequent manipulation of sales data. The verification by means of a data export - which is specified as DSFinV-K - is checked for changes and gaps by the tax office using verification software. Each cash journal entry/transaction is provided with an electronic signature from a technical security device (TSE). If transactions in the journal are manipulated, the chain of signatures is no longer consistent. Checking software can be used to find out at which point the manipulation has taken place at the touch of a button.

What must be recorded according to the KassenSichV?

Since 30.09.2020, cash registers in Germany must be equipped with a so-called technical security device (TSE), which ensures that individual records must be kept. The TSE signs and saves the cash register transactions on its internal memory and returns a code to the cash register. This code must be printed on every sales receipt. The data is stored in an unchangeable log (TSE TAR file), which must be exportable for the tax office. The electronic recording system must start a transaction for each business case that records the following data:

  • Time of the start of the process
  • a unique and consecutive transaction number
  • Type of procedure
  • Data of the procedure
  • Type of payment
  • Time of completion or termination
  • TSE signature data as QR code or in plain text

DSFinV-K​

What's the DSFinV-K?

The abbreviation stands for "Digital interface of the tax authorities for cash register systems". It means that all companies that use an electronic recording system (cash register, POS, ERP system, etc.) must use the same structure for data entry and data export. During an audit by the tax office, the data (DSFinV-K data export) is analyzed for errors/gaps/data inconsistencies by an audit software called IDEA.
