Fiscal Devices

FDM 2.0​

The EFR requires an exclusive FDM (Fiscal Data Module) for each cash register.

Zwartedoos FDM​

Each FDM is configured by FPS Finance for specific POS serial number(s). This configuration is transmitted to the FDM via its network connection, and the FDM only accepts transactions from the POS serial(s) it has been configured for.

The FDM connects via a network connection and requires no manual setup. It can be accessed either by its IP address or hostname (which is the FDM serial).

tip

Zwartedoos recommends using the fixed IP address of the Fiscal Data Module instead of its hostname to avoid DNS resolution delays and improve communication performance.

Example Address: http://bmc08000048.local
