Germany: The Role of the Cash Register Security Ordinance (KassenSichV) and the TSE

Since January 1, 2020, Germany’s Cash Register Security Ordinance (KassenSichV) requires all electronic cash registers to use a certified Technical Security System (TSE) that securely records and signs each transaction to prevent tampering. Businesses must issue receipts for every sale and ensure their systems produce audit-ready data in the standardized DSFinV-K format.
