Abstract: When a remote service terminal is to be connected, the present invention executes the following procedure. The lobby terminal selects a clerk terminal which can correspond to a consulting detail and the selected clerk terminal is connected to the lobby terminal and carries out a remote consultation. When the lobby terminal selects an unattended agent server, the lobby terminal retrieves the past reply corresponding to the consulting detail of the user and displays it at the lobby terminal. When the clerk terminal corresponding to the consulting detail becomes connectable while the unattended agent server is corresponding to the user of the lobby terminal, the unattended agent server takes over the consulting detail to the clerk terminal. When there is no clerk terminal to be changed when the consultation is over, the unattended agent server sends the inquiry data which is to be replied to the user asynchronously to the clerk terminal by a communication means separately.

Abstract: An erroneous-operation preventive apparatus operable with an operation medium has a unit for receiving the operation medium. The unit includes first and second data modifiers and the operation medium stores first data, second data equal to the first data modified by the first data modifier, and third data equal to the first data modified by the second data modifier. When the operation medium is set in the unit, the first and second modifiers modify the first data from the operation medium. The modified first data is compared with the second and third data from the operation medium to decide the correctness of operation when the comparison results indicate a predetermined relationship between the modified first data with the respective second and third data.
