Abstract: A method for managerial clerk inspection in an on-line system comprising a plurality of regular clerk terminal units operated for transactions by regular clerks, a terminal unit dedicated to a managerial clerk and operated by the managerial clerk for acknowledgement of transactions, a central unit and a terminal control unit interposed between the central unit and the regular clerk terminal units as well as the managerial clerk terminal unit. When the regular clerk operates the regular clerk terminal unit, a transaction message is transmitted from the regular clerk terminal unit to the central unit, and the central unit decides whether the transaction requires acknowledgement by the managerial clerk.
