Send last result
Overview
Whenever the POS terminal runs one of the following transactions, commanded by the remote device: Payment (all types), Offset, Credit, Pre-authorization (request, integration, and closure) it saves the transaction result message sent by the remote device in its static memory.
If saved, it includes the “additional data from GT result” message. When the remote device wants to retrieve these results, it sends the terminal this command.
The terminal does not run any sequence check and always keeps this message even if any other transaction was run that does not require the result message to be saved (example, DLL, totals, etc.).
