    Fiscal service environment


    The "fiscal4brand" service acts as an intermediary between the cash register system and the financial administration. The service processes the data from the POS system and ensures that it is formatted according to the requirements of the financial administration. 

    In addition, the "fiscal4brand" service offers additional functions such as storing data, creating reports and managing certificates.

    Below you'll find schematics in how the clients works via middleware and a signature unit. There are three examples shown here. First the initialization of the API and the fiscal service. Next ist the creation and processing of a fiscal transaction und last but not least, the execution of an exported function is shown.

    Fiscal API  This is the API interface for the Fiscal Service by acto-soft. 
    Exported Function  This is a function provided by the fiscal service, which can be run remotely by the client application. 
    Text Index  This represends a number which will be converted to a specified text template. This is used acto-soft internally with it's cash register application. 
    OID  The short form of "Object ID". This is used in our fiscal database and it is basically a GUID. 
    Reaction Advice  Depending on the outcome of a transaction processing, the fiscal service tells the client what to do next. The Reaction advice could be OK (all fine), Warning (The client should show the error message to the user), Rollback (The last transaction should be undone), RollbackClose (The last transaction should be undone and the client needs to shut down) 
    Print Data  In some cases, the fiscal service provides the printed receipt in text form. 
    Symbology  This term is used in regards to barcode printing. The symbology represents a type of barcode, like QR-Codes.
