According to the law of the Kassensicherungsverordnung (KassenSichV), there has been an obligation to use tamper-proof recording systems since January 1st, 2020.
These electronic recording systems must be equipped with a Technical Security System (TSS).
Every cash register manufacturer, integrator or taxpayer is obliged to print the information on the receipt in a form that is human-readable or as a QR code.
With the help of the DF QR code checker from Deutsche Fiskal GmbH, you can check whether the QR code was created in accordance with the specifications of DSFinV-K 2.2.
Scan the QR code with your mobile device and receive the individual values either in a clear arrangement or as raw data.
