Abstract

A product management system has a database, an owner identification device, a card issuance device, and a checking device. The database correlates and stores therein product and owner information in relation to the owner of the product. The owner identification device wirelessly reads out information from an IC tag, which is fixed to the product and has stored therein product information, and also reads out from the database product information and correlated owner information. The card issuance device issues a card having a storage medium for storing the information. The checking device checks and compares information read out from the card, information read out from the IC tag, and information read out from the database, to thus validating the owner of the product. The product management system prevents a product which has been sold from being illegally used by or dealt with a person other than a valid owner.
