Terminal protocol GPE Subtotal Connector

[ | version 3.1]


The connector is forbidden for use by the platform background agent.

Connector processing type: Row by row!

The Terminal protocol GPE SubTotal Connector ensures the connection of external cash register systems (ECR) with the payment terminal during subtotal processing. Its purpose is to compare the number and sum of amounts of all transactions made between the payment terminal (or cash register) and authorization system. It is only used for the immediate comparison of the accumulated transaction status. The connector can convert requests from cash register systems entered in a user-friendly format (e.g., CZK 100) into a format the payment terminal understands. Subsequently, it can transform the transaction processing results returned by the terminal into a format the POS system understands.
