efsta Compliance as a Service: The secure solution,
to comply with the KassensichV regulations in force since 2020 and to fiscalize correctly:
Cash registers in Germany must be connected to a certified TSE in accordance with the KassensichV, all business transactions must be signed by this TSE and special data exports such as TSE tar files or a DSFinV-K export must be presented on request - with the use of the efsta EFR Middleware you are legally compliant!
The German Ministry of Finance's Cash Register Security Ordinance sets standards to prevent cash register manipulation. From 30.09.2020, German cash registers must have a technical security device (TSE). This stores transactions, issues a code and secures the data for the tax office.
Since December 22, 2016, the Federal Ministry of Finance (BMF) has created the new regulation of Section 146a AO in the "Cash Register Act". According to this, electronic recording systems (cash register systems) must have a certified technical security device - TSE for short - from January 1, 2020. This TSE is intended to prevent manipulation of the digital (cash register or receipt) data.
We have the solution! Starting with the required document linking, through the use of TSEs to DSFinV-K data exports - efsta stands for legal compliance! All BSI-certified TSEs - regardless of whether hardware or cloud-based - can be used via efsta middleware - you decide which TSE best suits your POS solution - open to all technologies!
Selected TSEs can be purchased in the efsta portal and can be self-configured or centrally configured with the efsta system - TSE changes are also easy to administer!

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).
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.
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
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!
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.
The technical security device (TSE for short) is the legally required security module in electronic cash registers that ensures the complete and unalterable recording of all cash register transactions.
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
