However, the CPU 21 may obtain points to be given to the user according to the purchase price of the product sent from the POS terminal to the POS terminal connection device 26.

The CPU 21 transmits the unique bar code read in step S32 1 and the point input in step S32 2 from the communication device 27 to the server device 1 via the Internet 4 (step S 3 2 3). In the server device 1, the communication device 15 receives the unique barcode and the point (step S3401). The CPU 11 of the server 1 retrieves the user ID corresponding to the received unique bar code from the barcode database 18 and registers the received point in the user database 17 corresponding to the user ID. The added points are added (step S 3 4 2). This is the end of the point accumulation processing.

FIGS. 12A and 12B are flowcharts showing the point exchange processing. This process is performed by the mobile phone 3, the shop terminal device 2, and the server device 1. When a user who intends to exchange the accumulated points for another product inputs a predetermined instruction from the input device 34 of the mobile phone 3, the CPU 31 requests the exchange of the point from the communication device 36. (Including information indicating a power point) should be transmitted to the server device 1 via the Internet 4 (step S401). The communication device 15 of the server device 1 receives this exchange request and passes it to the CPU 11 (step S444).

The CPU 11 refers to the user database 17 to determine whether points equal to or higher than the requested point have been accumulated as points of the user (step S4442). If more points have been accumulated than the requested point, CPU 11 returns to the requested point. A replacement barcode is issued accordingly (step S4443). The CPU 11 reads the user's unique percode from the percode database 18, generates an encryption key corresponding to the percode, and encrypts the replacement barcode using the generated encryption key (Step S). 4 4 4).

The CPU 11 transmits the encrypted exchange bar code from the communication device 15 to the requesting mobile phone 3 via the Internet 4 (step S445). On the other hand, if points equal to or greater than the point requested in step S444 have not been accumulated, CPU 11 transmits a message notifying that the replacement barcode cannot be issued from communication device 15 to Internet4. Is transmitted to the requesting mobile phone 3 via the server (step S444). In the mobile phone 3, the communication device 36 receives the exchange bar code transmitted in step S445 or the issuance-disabled notification message transmitted in step S446 (step S402). ). The replacement par code is stored in a predetermined area of the RAM 33. The CPU 31 of the mobile phone 3 determines whether or not the replacement barcode is received in step S402 (step S403).

The user of the mobile phone 3 operates the input device 34 to display a replacement par code on the display device 35, and presents the mobile phone 3 to a clerk at a member store who wants to exchange points for a product. (Step S404). The clerk at the member store causes the bar code reader 24 to read the replacement par code displayed on the display device 35 of the mobile phone 3 (step S 4 21).

The user of the mobile phone 3 is now displayed on the display device ₃₅ a unique barcode one de in an operation child input device 3 4 presents the mobile phone 3 to the clerk merchant (Step S 4 0 Five ) . The clerk at the member store reads the unique barcode displayed on the display device 35 of the mobile phone 3 into a barcode reading device. 24 is read (step S 4 2 2). The CPU 21 of the shop terminal device 2 uses the unique barcode read in step S422 to decrypt the replacement barcode read in step S421 (step S432). ₀

The CPU 21 transmits the decrypted bar code for exchange from the communication device 27 to the server device 1 via the Internet 4 (step S424). In the server device 1, the communication device 15 receives the bar code for replacement (step S444). The CPU 11 refers to the percode database 18 (step S444) and determines whether the received replacement barcode is valid, that is, the received replacement barcode is registered in the barcode database 18. Then, it is determined whether or not the used flag is within a predetermined time from the issuance and the used flag is not set (step S444).

If the received replacement parcode is valid, the CPU 11 acquires the user ID registered in the barcode database 18 in association with the replacement barcode, and responds to the user ID. The points in the user database 17 are subtracted by the value indicated by the bar code for replacement, and the used flag is set (step S450). The CPU 11 adds the points in the member store database 17 corresponding to the store terminal device 2 that is the transmission source of the replacement barcode by the value indicated by the replacement barcode (step S4). 5 1).

The CPU 11 sends a point availability notification message indicating that the point corresponding to the replacement bar code can be exchanged for a product from the communication device 15 to the store terminal device 2 via the Internet 4. Transmission is performed (step S4 52). If the replacement bar code is not valid in step S444, the CPU 11 exchanges a point corresponding to the replacement bar code with the product. A point use disapproval notification message indicating that the exchange cannot be made is transmitted from the communication device 15 to the store terminal device 2 via the Internet 4 (step S4453).

In the store terminal device 2, the communication device 27 receives the point availability notification message transmitted in step S452 or the point unavailable notification message transmitted in step S453 (step S4). twenty five ) . The CPU 21 causes the display device 25 to display the enable notification message or the disable notification message received by the communication device 27 in step S425 (step S426). The point exchange process is completed as described above. However, if the use notification message is displayed on the display device 25, the user can exchange points for goods at the store and receive the goods. .

As described above, according to the point exchange system according to the present embodiment, when exchanging points accumulated by a user for a product, not only the unique bar code constantly managed in the mobile phone 3 but also the However, a special replacement par code is required for point exchange. Since the replacement par code is issued each time a point is exchanged, it is more difficult to forge than a unique bar code.

The bar code for replacement is invalid after a predetermined time has passed since its issuance, and points cannot be replaced with goods. The exchange barcode transmitted to mobile phone 3 is encrypted with a secret encryption key. It is almost impossible to forge a replacement barcode within the time available for redeeming points. Therefore, it is possible to prevent the points accumulated by the user from being illegally exchanged for another product.

The replacement barcode is decrypted using the unique percode as a decryption key, and is encrypted using an encryption key (different from the unique barcode) corresponding to the unique barcode. A unique barcode as a decryption key is released, The encryption key is not made public. The fact that the decryption key is a public key and the encryption key is a private key is the opposite of the usual public key cryptosystem, but the method of generating an encryption key from a unique barcode is disclosed. Therefore, a third party cannot easily generate an encryption key from a unique barcode. Even if the decoding method is known and the replacement barcode is read by the barcode reading device 24 in a decrypted state, it is transmitted from the store terminal device 2 to the server device 1. The replacement barcode is different from the original replacement barcode because the barcode is further decrypted. Therefore, by using the encryption and decryption methods described above, points can be prevented from being exchanged improperly.

The present invention is not limited to the above embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

In the above embodiment, even if a point exchange request is received, the CPUI 1 of the server apparatus 1 stores points in the user database 17 as points of the user or more as the requested points. If not, a replacement barcode will not be issued. In other words, user data

—The user's points stored in space 17 were not negative.

However, even if the user's points become negative (including when it is already negative), a replacement parcode may be issued. In this case, upon receiving the point exchange request in step S444, the CPU 11 may perform the processing in step S444 without executing the processing in step S444. . However, negative points need to be settled in some way.

Figure 13 shows the invoicing process to settle negative points. This is a flowchart showing the process. This process is executed when a timer interrupt is generated at predetermined time intervals by an internal timer of the CPU 11 of the server device 1. In order to execute this processing, the server device 1 is further provided with a printer (not shown).

In the invoicing process, the CPU 11 sequentially performs a loop process for each user registered in the user database 17 (steps S501_S501,). In the processing in the loop, the CPU 11 extracts a point included in the record of the user to be processed and determines whether or not this point indicates a negative value (step S5). 0 2).

If the points indicate a negative value, the CPU 11 issues an invoice to the user in question and charges for the value (money or not) according to the negative value. (Step S503), and print on paper by the printer (Step S504). The printed invoice will be delivered to the user by mail or other means.

If the point value does not indicate a negative value or if the printing of the invoice is completed, the processing for one user is completed. If the CPU 11 determines in step S501 that the processing in the loop has been completed for all the users registered in the user database 17, the processing exits the loop and ends the bill issuing processing.

As described above, in this point exchange system, points can be made negative, and bills can be issued in accordance with the negative value of points, so that credit cards and prepayments can be made. It is possible to realize a point exchange system having both functions of a card and a point card.

In the above embodiment, the replacement par code is disabled after a certain period of time from its issuance, and the replacement per code is encrypted. They were trying to prevent points from being forged and illegally exchanged for goods. However, the replacement barcode forgery prevention technology applicable in the present invention is not limited to this.

For example, an electronic watermark may be embedded in a replacement barcode. This digital watermark can be obtained by intentionally changing the replacement barcode from the original content of the replacement barcode to the extent that error correction is possible. As such a digital watermark, it is possible to use a two-dimensional code obtained by intentionally adding a geometric pattern capable of detecting errors with the two-dimensional code. Here, a company logo, service name, or the like can be used as the geometric pattern. This makes it possible to visually determine from where the replacement barcode was issued.

A program written in the JaVa (trademark) language or the like is embedded in the replacement barcode, and by the operation of this program, the barcode for replacement is passed when a predetermined time elapses after being received by the mobile phone 3. It is also possible for one to be self-supporting. This program may have a function of periodically checking the time with the server device 1. The program may have a function of notifying a user by sounding an alarm or changing the color of the bar code when the replacement bar code is about to expire. This program can have a function of automatically replacing an image or displaying character information and extinguishing a two-dimensional barcode after the expiration date of the replacement parcode.

The method for disabling the use of the replacement barcode after a lapse of a predetermined time from the issuance is not limited to the above-described method, and the replacement barcode delivered to the mobile phone 3 may include time limit information. The barcode reader 24 reads the time limit information when reading the replacement barcode, and the store terminal device 2 transmits the time limit information to the server device 1. Can be. The CPU 11 of the server device 1 can determine the validity of the replacement barcode based on the term information sent from the store terminal device 2.

If the unique barcode itself is forged, the points will not be used illegally, but the encryption key used to encrypt the exchange barcode may be decrypted. Once the encryption key is decrypted, the replacement barcode may be used improperly. Therefore, by updating the unique barcode at regular intervals in the server device 1, the risk of decryption of the encryption key can be suppressed, and the encryption bar is decrypted and the replacement barcode is used illegally. Damage can be minimized. The unique barcode can be transmitted from the server device 1 to the mobile phone 3 every time it is updated.

In the above embodiment, the unique barcode is issued by making a request from the mobile phone 3 to the server device 1, but is assigned from the beginning to the mobile phone 3 and stored in the ROM 32 in advance. It may be. The person who purchases the mobile phone 3 to which the unique barcode is assigned can automatically become a user of the service provided by this system. In this case, the unique percode assigned to the mobile phone 3 from the beginning can be updated simply by using it as a unique barcode at the time of initial setting.

FIG. 14 is a flowchart showing the unique parcode updating process. This process is executed when a timer interrupt is generated at predetermined time intervals by an internal timer of the CPU 11 of the server device 1.

In the invoicing process, the CPU 11 sequentially performs a loop process for each user registered in the user database 17 (steps S601-S601 '). In the processing in the loop, CPU 11 is not Refers to the barcode database 18 using the user ID of the user as a key, and creates a new unique barcode that is different from the unique barcode used by the user and has not been used by other users. A bar code is issued (step S602).

The CPU 11 rewrites the issued new unique barcode into the unique barcode registered so far and registers it in the barcode database 18 (step S603). The CPU 11 transmits the issued new unique bar code from the communication device 15 to the mobile phone 3 via the Internet 4 (step S603).

When the transmission of the new unique barcode ends, the processing for one user ends. When the CPU 11 determines that the processing in the loop has been completed for all the users registered in the user database 17 in step S601 ', the CPU exits the loop and ends the processing on the server device 1 side.

In each mobile phone 3, when the communication device 36 receives the unique barcode (step S621), the CPU 31 overwrites the unique barcode in a predetermined area of the RAM 33, and the mobile phone 3 Update the unique barcode to be stored in the server (step S622). This ends the unique barcode update process.

In the above embodiment, the replacement barcode is completely different from the unique barcode, and when the user attempts to exchange points for a product, the unique percode and the replacement parcode are different. However, they had to be read separately by a bar code reader 24. On the other hand, the unique bar code and the replacement bar code may be displayed on the display device 35 at the same time. As a result, it is only necessary to read the par code once when exchanging points. In the above embodiment, the replacement parcode itself indicates the point at which the user has requested replacement with the product. However, the replacement parcode may be in a form independent of the points. Since the replacement barcode is stored in the barcode database 18 in association with the point, the user's point is subtracted in step S450 and the merchant point is added in step S451. This means that the operation may be performed according to the points stored in the barcode database 18 in association with the replacement barcode.

In the above embodiment, the unique barcode and the replacement parcode are displayed on the display device 35 of the mobile phone 3 as a barcode having a two-dimensional two-dimensional matrix pattern. Or a bar code having a three-dimensional pattern. The three-dimensional bar code is a two-dimensional bar code displayed on each surface of a cube formed of, for example, a polygon, and the polygon is rotated by an application such as Java. The shop terminal 2 can recognize all the two-dimensional barcodes displayed on each side of the cube by the rotation of the polygon. Three-dimensional barcodes can contain a greater amount of information as the number of screens increases.

For example, when the store terminal device 2 and the mobile phone 3 are configured to be able to directly communicate by applying the blue tooth technology or the like, even if the information is invisible, the unique bar code and the bar code for exchange as described above can be used. Can be applied instead of the code.

In the above embodiment, the CPU 11 of the server device 1 generates the unique barcode or the replacement parcode in the same manner no matter which user sends the barcode to the mobile phone 3 of any user. However, the size and number of dots of the display device 35 of the mobile phone 3 vary depending on the model. Any mobile If it is assumed that a unique barcode or a replacement barcode is generated so that the telephone 3 can also display it on the display device 35, the pattern of the unique barcode and the replacement barcode is not simple. The risk of forgery increases.

In order to generate the most effective unique barcode and replacement barcode according to the model of the mobile phone 3, the server device 1 can include a model database 19 shown in FIG. The model database 19 stores the user ID and information on the model of the mobile phone 3 (including at least the size of the display device 35 and the number of dots) in association with each other.

When issuing the unique barcode in step S256, the CPU 11 of the server device 1 refers to the model database 19 to obtain the unique barcode corresponding to the model of the requesting mobile phone 3. Can be issued. When issuing a replacement barcode in step S444, the CPU 11 refers to the model database 19 and issues a replacement barcode corresponding to the model of the requesting mobile phone 3. Can be.

The unique barcode and the replacement barcode transmitted from the server device 1 to the mobile phone 3 may be compressed. The CPU 11 of the server device 1 generates a unique bar code or a replacement bar code irrespective of the model, reads the model of the requesting mobile phone 3 from the model database 19, and according to the model. Unique or replacement barcodes can be compressed. If the unique percode or replacement barcode is of the self-decompression type, the CPU 21 of the store terminal 2 performs exactly the same processing as above using the thawed unique percode or replacement barcode. It can be carried out.

By providing the model database 19 in the server device 1, the unique barcode and the replacement barcode transmitted to the mobile phone 3 as described above are If the mobile phone 3 is a new type and the number of display dots on the display device 35 is large, a fine pattern bar code is displayed. A possible bar code can be generated. This allows the display device 35 to display the unique barcode or the replacement barcode by making the most of the function of the display device 35. Even if the user frequently changes the model of the mobile phone 3, if the model registered in the user database 28 is changed, a two-dimensional barcode suitable for the new model will be obtained. It is especially effective for applying

In the above embodiment, the mobile phone 3 having the display device 35 is applied as the terminal device that displays the unique barcode and the replacement parcode and presents it to the store clerk. A mopile terminal capable of communicating with 1 (for example, a PDA (Persian Digital Assis- tant s)) can be applied instead of the mobile phone 3. This terminal may be connected to the server device 1 by wire. Since a mobile device such as a PDA generally has a display device larger than the mobile phone 3, it has a more complicated pattern and has a unique barcode and a replacement barcode that contain a large amount of information. Can be used. If information that is invisible due to the application of Bluetooth technology or the like is used instead of the unique barcode and the replacement barcode, the terminal may not have a display device. .

In the above embodiment, the points accumulated by the user are deducted when the user exchanges a product at a member store. However, points may be deducted when a replacement parcode is issued. When a bar code for replacement is issued, a part of the points corresponding to the replacement par code is deducted, and when the commodity is exchanged using the replacement par code, the points are further deducted. Also Good. Thus, the request for issuing the replacement parcode from the mobile phone 3 to the server device 1 is not neglected, and the load on the server device 1 can be reduced.

In the above-described embodiment, the unique barcode and the exchange barcode are set as a set and are used for accumulating and exchanging points. However, the unique barcode assigned to the mobile phone 3 can be used for other purposes such as customer management independently of the replacement barcode.

In the above embodiment, the programs shown in the flowcharts of FIGS. 9 to 12B are stored in the memory 12 of the server device 1, the memory 22 of the store terminal device 2, or the ROM 32 of the mobile phone 3. As described. However, all or some of these programs may be provided separately from the hardware.

FIG. 16A shows a first example of a method for providing a program. The server device 1 and the store terminal device 2 each drive a computer-readable recording medium 55 such as a CD_ROM or a DVD_ROM, and further include disk drives 51 and 52 for reading data. The CPUs 11 and 21 can cause the disk drives 51 and 52 to read the program recorded on the recording medium 55 and install them in the memories 12 and 22 respectively. . The mobile phone 3 further includes a card slot 53 for inserting a ROM card 56 and reading data. The CPU 31 may sequentially read out and execute the instructions of the program recorded on the ROM card 56 via the card slot 53.

FIG. 16B shows a second example of a method for providing a program. The processing programs for the server device 1, the store terminal device 2, and the mobile phone 3 are stored in the fixed disk device 58 of the Web server 57 on the Internet 4. You. When a request to send a program is sent from the server device 1, the store terminal device 2, or the mobile phone 3, the Web server 57 converts the program stored in the fixed disk device 58 into a data signal and transmits it to the carrier wave 59. It is superimposed and returned to the requesting device via the Internet 4. When the server device 1, the store terminal device 2, or the communication device 15, 2, 7, 36 of the mobile phone 3 receives the program transmitted by being superimposed on the carrier wave, the CPU 11, 1, 2, 3 1 The program can be installed in memory 12, 22, or ROM 32. Here, as the ROM 32 of the mobile phone 3, a flash memory capable of electrically writing and erasing data can be applied. Industrial applicability

The points possessed by users and exchanged for other products are not limited to those accumulated by purchasing products.

This point may be a mileage that accumulates at the distance the user has boarded the airplane. This point may be given by the number of game balls and medals obtained by the user in a game such as a pachinko or slot machine. This point may be awarded when a user browses a Web page with a banner advertisement.

This point may be accumulated according to the amount of money paid by the user in advance, such as a prepaid card. In other words, the points themselves may indicate monetary value. As shown in Fig. 13, it is possible to make the value of a point negative, and the process of issuing a negative invoice every predetermined period is performed when the point itself indicates monetary value Especially effective.

The points (including minus) accumulated by the user are given a predetermined interest. You can also attach a pawn point every time a certain value is reached. In addition to accumulating points when purchasing products, it is also possible to add a point when introducing a friend as a user.

The points accumulated by the user may be exchanged for products by a method in which the provider selects the desired product from the products in advance and mails it, delivers it to the home, or receives it at a member store. The points accumulated by the users may be made available for the acquisition of product discounts. The points accumulated by the user may be such that priority reservations such as seats for concerts can be made. If the point itself indicates monetary value, it can be cashed back to the user.
