Are you a taxpayer and required to register your POS system with the German tax authority (Finanzamt) yourself?
This article explains how to access the BSI certificate ID and the serial number of the Technical Security Device (TSS) via the fiskaly system.
Other information such as the software version, model, or serial number of your POS system must be obtained directly from your POS provider or the provider of your POS software.
BSI Certificate ID
You can find the current BSI certificate ID of the fiskaly TSS in our article: Which BSI certificate ID should be used for a fiskaly TSS?
TSS Serial Number
The TSS serial number can be found on a receipt from your POS system:
- either in the QR code, which you can scan using our free fiskalcheck app - Google Play Store (Android) / Apple App Store (iOS)
- or directly in plain text on the receipt if provided (part of the TSS signature)
Details about the fields contained in the TSS signature can be found in this article: Which data should be recorded on a receipt?
