What happens if the trust service provider (TSP) cannot provide signatures to fiskaly?

Tip

Last updated on 2025-09-09.

If SIGN AT cannot request signatures from a certified trust service provider (TSP), receipts will be signed using a substitute signature. The receipts will include the note Sicherheitseinrichtung ausgefallen (German from “SCU unavailable”). These receipts are valid and will be contained in the DEP7 export. When the TSP is reachable again, SIGN AT automatically creates a zero-valued receipt marking the end of the outage.
