Abstract: A system (1) transmits cargo booking requests to airline booking systems (A), and receives feedback from them. A server (2) of the system (1) has templates for each airline system (A), and a switch (3) generates signals emulating input device inputs to a dedicated terminal (B) for each airline system (A). These commands populate a request screen if the airline system (A) as displayed on the dedicated terminal (B). The system (1) also captures screens displayed on the dedicated terminals (B) and generates feedback for agents at agent systems (6). The airline systems (A) thus can continue to operate as if they were interfacing with only dedicated terminals, thereby providing excellent access control for security.
