GLOSSARY
KassenSichV (German Cash Register Security Ordinance)
German cash register security rules requiring protected transaction records and usually a certified TSE.
KassenSichV is the German Cash Register Security Ordinance. It requires electronic cash registers to protect transaction records against tampering, typically through a certified TSE. The goal is to make every sale, refund, and cancellation verifiable during an audit.
For operators, KassenSichV matters most at the daily close and during tax audits. The POS should handle signing, receipts, exports, and record retention in the background so staff can focus on service.
