Electronic Data Processing plays a firm and indispensable role in every business transaction. Despite sophisticated auditing methods, financial administrations across the EU are constantly faced with new challenges due to the use of new technologies and relentless technological progress. Systems are becoming increasingly complex, business transactions are done online and across borders and therefore difficult to trace. In almost all European countries measures are being - or have been - taken to allow for the introduction of fiscal control systems. The lack of a universally accepted standard has led to a massive increase in the work of software producers and, at the end of the day, commercial enterprises. 


efsta offers a process (patent pending) for the documentation of business transactions required to be recorded and guarantees the integrity and unchangeability of the data received for a period of ten years. (record retention period).

How it works

The process works with a Software-BlackBox, which operates as a background service on a PC. With every relevant transaction the cash register or billing software transfers a fiscal record (receipt number, cash register ID, receipt total) via the open API connection to the BlackBox.

The BlackBox confirms receipt with a distinct fiscal number (fiscal signature), which is printed onto the receipt. After calculation of the grand total the transaction record is immediately encoded locally and added to the fiscal data, which in turn is transferred to the efsta data center.


The efsta process does not require changes in infrastructure and can be used internationally independent of operating system, hardware or software producers

Fiskal-Middleware – EFSTA im internationalen Einsatz

Die EFSTA-Lösung wurde für den Einsatz im internationalen Umfeld konzipiert. Durch die Integration des EFR in das jeweilige Kassensystem können Daten an diverse europäische Fiskalsysteme (meist Online-Systeme wie in Kroatien oder Slowenien) übermittelt werden. Dadurch kann ein Kassensystem in vielen Ländern, welche fiskale Sicherungssysteme vorschreiben, eingesetzt werden, ohne die Kassensoftware zu ändern. Die technisch-organisatorische Abwicklung sowie die laufende Wartung erfolgt durch EFSTA (z.B. Fiskalisierungs- und Zertifizierungsprozesse). Ebenso ist es möglich das in Deutschland konzipierte Insika-System über die EFSTA-Lösung anzusprechen.

Die EFSTA-Infrastruktur ermöglicht weiters die Ausstellung digitaler Kassenbelege an Konsumenten. Mehr dazu finden Sie unter: Advanced Services
