Abstract

A transaction control system is disclosed wherein a center computer is connected through communication circuits with a plurality of terminal devices and wherein the users of the terminal devices do not suffer disadvantages in dealing produced by differences in transmission time with respect to the center computer. With this transaction control system, prior to the ordinary processing, the transmission time required to effect information transmission between the center computer and the various terminal devices is measured. Using the result of this measurement, an adjustment time is then set in each terminal device such as to make the transmission time coincide with a reference time. When in receipt of transaction information, each terminal device displays this transaction information after the lapse of the adjustment time after the time-point of its reception. And when a transaction request is input at each terminal device, this transaction request is transmitted to the center computer when the adjustment time has elapsed after the time-point of its input.
