Network Traffic

The requirements on network quality depend on the number of Mobile POS clients used and how intensively they are used. The required network quality can be calculated based on how much data is transferred between the Mobile POS and Flow Service.

Here is an example from a traffic measurement with 1 Mobile POS Client. If more clients are used, the data has to be multiplied accordingly.

The measurement does not include providing logs from Mobile POS to the cloud system or Flow Service. The logging was deactivated in this case.

Initialization Messages

During startup, the Mobile POS connects to the Flow Service and loads the required data (translations, tableaus, initial data, etc.). The Mobile POS Client sends the last transactions to the Flow Service, which are used in recovery cases.
