    KassenSichV in 2023 - What will change

    At the beginning of the year, a further transitional period of the German KassenSichV expired and the regulation was enacted for all POS systems. Every electronic POS system must therefore be equipped with a certified technical security system (TSS) as of January 1, 2023.

    TSS customers basically have the option of integrating cloud TSSs or hardware TSSs. There are huge differences in terms of certification, performance spectrum, practicability and costs.

    QR code replaces legible TSS signature on receipt

    The decision of the Federal Council allows a QR code to be printed as an alternative to the data issued in readable form. This can shorten a receipt and thus save costs as well as resources.

FAQ's about the German KassenSichV.

Here you will find the answers to the most frequently asked questions about the KassenSichV

The German KassenSichV (Cash Register Security Ordinance) is designed to prevent the manipulation of basic digital records in companies. It regulates the technical requirements for electronic recording and security systems, such as cash register systems. From January 1, 2020, cash registers in Germany must be equipped with a manipulation protection - a so-called technical security system (TSS). The exact requirements for the technical security system are defined in the technical guideline BSI TR-03153. You can read more about this in our blog article on TSS.

The origin of this regulation is Section 146a of the German Fiscal Code (AO), which sets out the regulations for bookkeeping and records kept using electronic recording systems. The German KassenSichV specifies the requirements of the GoBD - the principles of proper accounting - in § 146a AO. It defines the security of digital cash register systems and regulates:

  • Which electronic recording systems are included by the regulation of § 148 AO.
  • When and how logging must take place. How the data must be stored.
  • What the interfaces must look like.
  • It also contains rules on the requirements for documents to be issued and the costs of certification.

The electronic records system must start a transaction for each business case that records the following data:

  • Start time of the transaction
  • A unique and consecutive transaction number
  • Type of transaction
  • Dates of the transaction
  • Type of payment
  • Time of completion or termination
  • A verification value and
  • The serial number of the electronic recording system or the serial number of the security module.

Suppliers of cash registers, cash register systems and software or recording systems that record business transactions (e.g. accounting programs and similar) are directly affected by the German KassenSichV. They must act now and prepare their products and systems for the new rules as quickly as possible.

In a broader sense, all business owners who work with these POS and recording systems are also affected. They must ensure that the systems or software they use are actually compliant with the KassenSichV.

According to the BMF, a physical identity of security module and storage medium is not required. This means that the TSS can be fulfilled with cloud storage as well as with a conventional data carrier (memory card or similar). We recommend the contemporary and future-proof variant of storage in the cloud. Here you can find more information about the fiskaly TSS.
