Is the POS system compliant with tax office requirements (KassenSichV / TSE)?

Yes, absolutely. Security and legal compliance are our top priorities. Kassenheld meets all legal requirements in Germany, including the Cash Register Security Ordinance (KassenSichV) and integration with a Technical Security Device (TSE). This means you are fully prepared for any inspection.
In addition, Kassenheld ensures data security even in the event of connection issues: If the internet connection fails, the system temporarily stores all transaction data locally on the POS and automatically uploads it to the cloud in a tamper-proof manner as soon as the connection is restored. Your data is therefore never lost.
