Abstract: This system is applied to a VAS having, as members, apparel makers which manage goods using apparel numbers and retail shops which manage goods using shop goods codes. The system tally manages the goods of all the members using unity codes. The apparel numbers are corrected as needed, and the corrected apparel numbers are incorporated in a unity code system. A code conversion table representing a correspondence between the unity code and the apparel number or the shop goods code is prepared. When this code conversion table is looked up, a management code is converted between the apparel number, the shop goods code, and the unity code, all of which represent the same goods.

Abstract: A delivery service management system utilizes a two-dimensional bar code having key information for specifying the source of a material and content information of this material and attached in a delivery service, a two-dimensional bar code having key information for specifying the source of an item obtained by processing the material and content information of the item and attached in a delivery service, and a two-dimensional bar code having key information for specifying a seller of the item and content information describing a selling condition of the item and attached in a delivery service. Every time a delivery service has occurred between the material system, the processing system, and the selling system, the key information and the content information are received from the two-dimensional bar code to a database. Delivery service information associated with a given source is fed back to the given source represented by the key information from a set of pieces of received information.
