PURPOSE:To shorten a construction period, to reduce cost, to increase the number of fixed external terminal equipments to be connected, to prevent human errors generated at the time of construction and to reduce the physical fatigue of an operator. CONSTITUTION:Since data are exchanged by radio communication between the radio communication equipment 32 of a POS terminal equipment 31 and the radio communication equipments 34 of the fixed external terminal equipments 33, it is unnecessitated to install cables under ground. Also, since a portable type terminal equipment 21 capable of the radio communication with at least one of the POS terminal equipment 31 and the fixed type external terminal equipments 33 and also capable of being manually operated by the operator 4 is provided and the data are exchanged through the radio communication equipment 25 of the portable type terminal equipment 21, at the time of selling gasoline or the like, the series of operational burden at the time of fueling such as going back and forth between the POS terminal equipment and the fixed type external terminal equipments and an automobile 5 by the operator 4 every time of sales operation is reduced. |
