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.

Claims

1. A product management system comprising:

a) a database operable to correlate key information relating to a product and owner information in relation to an owner of the product, and storing the key information and the owner information therein;

b) an owner identification device operable to read out key information from an IC tag fixed to the product and having already stored therein the key information relating to the product, and to read out from the database owner information which has been correlated with the key information thus read out;

c) a card issuance device operable to issue a card having a storage medium for storing the key information; and

d) an identifying device operable to identify a valid owner of the product by checking and comparing key information read out from the storage medium of the card, key information read out from the IC tag, and key information read out from the database.

2. The product management system according to claim 1, wherein the key information in the IC tag is transmitted and received through wireless communication.

3. The product management system according to claim 1, wherein the key information in the storage medium of the card is transmitted and received through wireless communication.

4. The product management system according to claim 1, wherein the card and the IC tag store the owner information, and

the identifying device also permits reading out the key information from the database when the key information and the owner information read out from the card respectively agree with the key information and the owner information read out from the IC tag.

5. The product management system according to claim 4, wherein the card stores a card ID for identifying a card;

the database stores the card ID; and

the identifying device identifies an owner as a valid owner when the card ID read out from the card agrees with the card ID read out from the database and when the owner information read out from the IC card agrees with the owner information read out from the database.

6. A product management system for managing a product comprising:

a) a database which correlates product information and owner information relating to an owner of the product, and stores the product information and the owner information therein;

b) an IC tag fixed to the product, the IC tag comprising an IC tag storage medium having information stored therein;

c) an information transfer device operable to transfer information to and from the IC tag storage medium, and operable to transfer information to and from the database the owner information which correlates with information read out from the IC tag storage medium;

d) a control unit which identifies a valid owner of the product by checking and comparing information read out from the IC tag storage medium and information read out from the database; and

e) a card including a card storage medium having information stored therein, wherein the control unit identifies a valid owner of the product by checking and comparing information read out from the IC tag storage medium, information read out from the database, and information read out from the card storage medium.

7. The product management system of claim 6, wherein information is wirelessly transferred to and from both the IC tag storage medium and the card storage medium using radio frequency signals.

8. The product management system of claim 6, wherein the control unit also permits access to the information stored in the database when the information read out from the card storage medium agrees with the information read out from the IC tag storage medium.

9. The product management system of claim 6, wherein each card comprises a unique card identifier (ID) stored within the card storage medium thereof.

10. The product management system of claim 9, further comprising an information reading device provided with the product operable to read information from the card storage medium,

the card ID is stored within the IC tag storage medium, and

the control unit controls operation of the product based on the results of a comparison between the card ID read out from the card storage medium and the card ID read out from the IC tag storage medium.

11. The product management system of claim 6, wherein the card storage medium and the IC tag storage medium each comprise a rewritable portion and a read-only portion.

12. The product management system of claim 11 wherein each said read-only portion comprises a classification code which identifies whether the respective storage medium is fixed to a product or fixed to a card, and wherein the read-only portion further comprises a product identifier which uniquely identifies the product.

13. The product management system of claim 6, wherein the database comprises a product history data portion, and where the product management system stores event data related to events within a life cycle of a product within the product history data portion of the database.
