(54)Product identification data management system and product identification data management method


(57) The present invention relates to a product identification data management system and method. According to the present invention, an input device of a purchasing department reads a bar code and an RF tag as data of two identification data systems added to a product such that the identification data of the two identification data systems are related with each other. The read bar code data and RF tag data are stored and managed in first and second databases of a information department, respectively. When a user terminal such as a product data terminal issues a request to acquire predetermined data on the basis of the bar code data of the product, the predetermined data is retrieved from either or both of the first and second databases. The acquired data is returned to the user terminal. The consistency between identification data added to each product can also be checked.
