Technical FAQ are available in our partner area.


Especically for the KassenSichV (the cash register regulation), the BSI (Federal Office for Information Security) has made a comprehensive FAQ list available online. The BMF (Federal Ministry of Finance) provided an orientation guide for the application of § 146a AO and the KassenSichV. Both are very informative and worth reading!
