PURPOSE: To provide an information inputting system in which the speed-up of a customer accounting processing can be attained by a large-scaled retailing facility.

CONSTITUTION: In a flexible purchased product accounting system, a processing capability can be improved by quickly making a shopping cart empty by more than two checkers by using a portable bar code scanner/data terminal equipment 15 as one part of an auxiliary accounting station used at the time of congestion peak. The accounting system is individually provided with a module for scanning a purchased product and a module for receiving the payment of a customer. The check of the customer accepted at the time of payment can be processed in a real time through an electronic deposit transfer(EFT) instruction. Empty inventory can be complemented by using a system for labeling final delivery destination information obtained by bar-coding the stock, and packing into a container for delivery to an accepting/redelivering center, and the final delivery destination information is scanned and decoded so that the correct path of the complemented stock can be decided in the center.
