Then, the gold bullion card 1 and the decryption card 9 are inserted into the key card slot 12 (step S21). By this insertion, the key information reading means 16
, The decryption key information is read, and the data decryption means 18 is operated by this key information. That is, the data decrypting means 18 reads the issued data from the issued data file of the IC chip module 4 of the gold bullion card 1 and decodes the issued data based on the decryption program read from the decrypted card 9. After decrypting,
It is displayed on the display unit 14.

The seller confirms the displayed content (step S22), and if it is not valid (step S23).
NO) Immediately stop selling and take action. For example, when the issuance data is defective or not present at all, it can be estimated that the gold bullion card 1 has been forged or stolen before the issuance (step S24), and prompt measures can be taken thereafter.

On the other hand, if the issued data is valid (YES in step S23), the gold bullion card 1
Can be determined to be a legitimate route, and the sale is performed. Before this sale, the decryption card 9 is removed from the key card insertion slot 12 and the encryption card is inserted (step S25). In the same manner as when the issuance data is registered in step S2, the sales data such as the name of the seller, the place of sale, and the date of sale are input through the input unit 13 (step S2).
6) After confirming the contents, the sales data is encrypted and registered in the sales data file of the IC chip module 4 (step S27).

Thus, the gold bullion card 1 has its IC
The chip module 4 is sold with the issue data and the sales data registered.

2) Buyer operation (FIG. 6) When the gold bullion card 1 is brought from the buyer to the buyer,
The buyer purchases the same gold bullion card 1 as in step S21.
Then, by inserting the decryption card 9 (step S31), the card handling device 10 reads and decrypts various data, and confirms the contents (step S32).

If the issued data and the sales data are valid (YES in steps S33 and S34) and the purchase data has not been registered yet (step S3).
5), it can be determined that the gold bullion card 1 is a legitimate route, so the purchase is performed. At the time of the purchase, the decryption card 9 is removed from the key card insertion slot 12 and the encrypted card is removed. Is inserted (step S36),
In the same manner as when the issuance data is registered at the issuance stage, the input unit 13
Then, purchase data such as a buyer name, a purchase place, and a purchase date is input (step S37). After confirming the contents, the purchase data is encrypted and registered in the purchase data file of the IC chip module 4 (step S37). Step S3
8).

On the other hand, if the issued data is defective or nonexistent at the data confirmation stage (step S33).
NO), it can be estimated that the gold bullion card 1 has been counterfeited or stolen before the issuance (step S43), and if the sales data is defective or nonexistent even if the issued data is good (NO in step S34). It can be estimated that the gold bullion card 1 has been counterfeited or stolen during the period from issuance to before sale (step S44). If the purchase data has already been registered (YES in step S35), the purchase has been performed. Later, it can be estimated that the device has been stolen (step S45). That is, depending on the quality of each data, it is possible not only to determine whether the gold bullion card 1 is legitimate or illegal, but also to estimate the time of occurrence of any illegality.

Moreover, since the encryption and decryption by each of the handling devices 10 cannot be performed unless the encryption key 8 or the decryption card 9 is inserted into the handling device 10 and specific key information is input, For example, by giving the card only to the above-mentioned issuer, seller, and purchaser, it is possible to reliably prevent the data content from being secretly read or rewritten by other persons, The confidentiality of information can be ensured.

The present invention is not limited to such an embodiment, but may take the following forms as examples.

(1) The value objects handled in the present invention are not limited to the above-mentioned gold bullion, and the present invention can be applied to various value objects such as other precious metals and gift certificates (especially gift cards made of noble metals). .

(2) In the present invention, an IC chip may be directly attached to a value object such as gold bullion.

Even if the apparatus is configured to perform the decryption operation and the decryption operation, the confidentiality of the data can be ensured by notifying only the person concerned of the password.

When the above key medium is used, the key medium for encryption and the key medium for decryption are shared to make a single one, and when this key medium is attached to the main body of the apparatus, the operation for encryption is also decrypted. It may be configured to be able to execute a conversion operation.

(4) Regarding the encryption card and the decryption card, regardless of the issuer, the seller, and the purchaser, it is possible to have a common card. In the same way, the seller has an encryption card for the issuer that stores only the key information for the seller, the seller also has the encryption card for the seller that stores only the key information for the seller, and the buyer is the buyer that stores only the key information for the buyer. To have an encryption card for
For example, if the registration means is configured to allow only data registration in the issuance data file when the issuer key information is input, for example, the issuance data may be used by the seller or the buyer without the knowledge of the issuer. This can prevent the inconvenience of rewriting the IC data, and has the advantage that the confidentiality of the IC data can be further increased. If the password for encryption is entered as key information without using the encryption card, only the password for the issuer is issued to the issuer, only the password for the seller is issued to the seller, and only the password for the seller is acquired to the buyer. By notifying only the buyer password, for example, if the handling device is configured to allow only registration to the issued data file when the publisher password is entered,
As described above, the confidentiality can be further improved.

(5) The method described in the above embodiment can be applied to a case where a value object such as a gold bullion card 1 purchased by a buyer is returned to an issuer again and this value object is recycled many times. It is possible.
