Product history management method, apparatus, and program, label issuing method, apparatus, and program, and identification information issuing apparatus

摘要

A product history management apparatus issues to label issuing apparatuses identification information to be printed on a label affixed on a product produced in production steps from raw material production to final product production. An identification information receiving device receives from a label issuing apparatus associated with one of the production steps information printed on a label affixed in a production step immediately preceding the one production step. An identification information transmitting device issues new identification information relative to the received identification information and transmits to the label issuing apparatus associated with the one production step the issued identification information. An identification information storage device stores the received identification information in the production step immediately preceding the one production step in association with the issued and transmitted new identification information.
