The providing unit 21 is controlled. The CPU 20 further performs a detection process using the checksum using the checksum included in the electronic coupon information of FIG. If fraud or the like is detected by the checksum detection process, the control means 39 controls the refusal to provide the product, and controls the product providing unit 21.

  The CPU 20 of the vending machine 200 configured as described above functions as each unit of FIG. 8 by executing a program corresponding to the flowcharts shown in FIGS. 9 and 10, and the operation will be described based on this flowchart. To do. In this flowchart, the pair of steps S15 and S16, the pair of steps S17 and S18, the pair of steps S19 and S20, the pair of steps S21 and S22, the pair of steps S23 and S24, and the pair of steps S25 and S26 These may be arranged in any order, and FIGS. 9 and 10 show examples.

  In a state where the electronic coupon information is written in the second storage area 16 by the writing means 17, when the mobile phone 100 is held over the position of the reader / writer 23 of the vending machine 200, the CPU 20 reads the reader / writer in the flowchart of FIG. 23 is monitored (S11), and the electronic coupon information read by the reader / writer 23 after branching to YES is decrypted using the public key corresponding to the secret key used in the electronic coupon issuing server 300 ( S12), it is detected using application information, lot ID, serial number, etc. whether it is an electronic coupon related to the handling object (S13). Further, the reader / writer 23 reads the chip identification information IDm from the first storage area 15 and various information stored in the third storage area 19 in the above.

  As a result of the detection in step S13, it is determined whether the electronic coupon is a handling target electronic coupon (S14). A hash value is created for the data including the checksum, and a checksum process including comparison with the checksum of the electronic coupon information is performed (S15), and it is determined whether they match (is OK) (S16). If it becomes OK in step S16, the process proceeds to step S17.

  In step S17, the unique number information composed of the lot ID and the serial included in the electronic coupon information, the unique number information composed of the lot ID and the serial of the negative storage means 27 (which is illegally used), A comparison is made (S17), and it is determined whether they are inconsistent (OK) (S18). If it becomes OK in step S18, the process proceeds to step S19.

  In step S19, the reader / writer 23 compares the chip identification information IDm read from the first storage area 15 of the mobile phone 100 with the chip identification information IDm included in the electronic coupon information (S19). It is determined whether it is present (OK) (S20). If it becomes OK in step S20, the process proceeds to step S21.

  Steps S19 and S20 have the following significance. That is, the chip identification information IDm is stored in the first storage area 15 of the mobile phone 100 from the beginning, and when receiving the download of the application program AP1 (SS11), it is transmitted to the electronic coupon issuing server 300, Based on this, it is included in the electronic coupon information. Therefore, the chip identification information IDm in the first storage area 15 of the mobile phone 100 should match the chip identification information IDm included in the electronic coupon information. Therefore, the detection using the chip identification information IDm can prevent the electronic coupon from being used when it is illegally copied to another mobile phone 100B.

  In step S21, the unique number information (one used in the vending machine 200 once) composed of the lot ID and serial stored in the log storage means 26, and the lot ID included in the electronic coupon information. Is compared with the unique number information composed of the serial number (S21), and it is determined whether or not they match (S22). If it becomes OK in step S22, the process proceeds to step S23.

  In step 23, it is checked whether the negative flag information has been read from the negative flag area in the third area 19 of the mobile phone 100 (S23), and whether the negative flag information has been read (is OK)? Determine (S24). If it becomes OK in step S24, the process proceeds to step S25.

  In step 25, the log information of the unique number information of the used electronic coupon read from the terminal log area in the third area 19 of the mobile phone 100 is the coupon information read from the second storage area 16. Terminal log check, which is a check of whether or not the unique number information included in the ID matches, is determined (S25), and it is determined whether or not there is a match (S26). If it becomes OK in step S26, the process proceeds to step S27.

  In step S27, the CPU 20 logs the unique number information composed of the lot ID and the serial included in the electronic coupon, and the provision of the merchandise, which is a process such as discharging the merchandise by controlling the merchandise providing unit 21. The unique number information read from the second storage area 16 of the mobile phone 100 is written in the storage means 26 (S27) and the third storage area 19 of the mobile phone 100 is read in consideration of the use of the electronic coupon. Is written in the terminal log area as a log of the unique number information of the used electronic coupon (S28), and the process is terminated.

  If the electronic coupon is used again by reproduction or the like even though the electronic coupon has been used by performing the process of step S28, the third processing of the mobile phone 100 is performed in the processes of steps S25 and S26. The unique number information of the electronic coupon is detected in the log information of the unique number information of the used electronic coupon read from the terminal log area in the storage area 19. Therefore, the process proceeds to step S33, and the CPU 20 controls the merchandise providing unit 21 to perform merchandise non-provision, which is a process such as stopping the discharge of merchandise (S33). Thus, an appropriate electronic coupon transaction is realized. In addition, even when branching to NO in steps S14, S16, S20, and S24, the process proceeds to step S33, and the product is not provided. Therefore, in the case of fraud, the product (service) is not provided and is appropriate. Electronic coupon transaction is realized.

  In the above step S18, when the unique number information composed of the lot ID and the serial included in the electronic coupon information matches the unique number information composed of the lot ID and the serial of the negative storage means 27. The CPU 20 controls the reader / writer 23 to write the negative flag information in the negative flag area in the third area 19 of the mobile phone 100 (S31). The negative flag information can be, for example, unique number information including a lot ID and serial number of an electronic coupon related to unauthorized use.

  Similarly, in step S22, the unique number information composed of the lot ID and the serial stored in the log storage means 26, the unique number information composed of the lot ID and the serial included in the electronic coupon information, If the two match, the CPU 20 controls the reader / writer 23 to write the negative flag information in the negative flag area in the third area 19 of the mobile phone 100 (S32).

  Since it is detected that the negative flag information has been read in the processes in steps S23 and S24 by performing the processes in steps S31 and S32, the process proceeds to step S33, and the CPU 20 controls the product providing unit 21. Since the product is not provided, which is a process of stopping the discharge of the product etc. (S33), an appropriate electronic coupon transaction is realized without providing the product (service) in the case of fraud. Even when the processes of steps S31 and S32 are performed, the process proceeds to step S33 and the product is not provided. Therefore, in the case of fraud, the product (service) is not provided, and an appropriate electronic coupon transaction is performed. Is realized.

  Steps S21 and S22 have the following significance. That is, the unique number information including the lot ID and the serial number once included in the electronic coupon used in the vending machine 200 is written in the log storage unit 26 in step S27. Therefore, in steps S21 and S22, the unique number information composed of the lot ID and the serial stored in the log storage means 26, the unique number information composed of the lot ID and the serial included in the electronic coupon information, The electronic coupons already used in the vending machine 200 cannot be used. This process can prevent the vending machine 200 from using the electronic coupon that has been used once illegally in the mobile phone 100 or in another mobile phone 100B.

  Here, a method for recording the unique number information in the terminal log area in the third storage area 19 of the mobile phone 100 will be described. The terminal log area in the third storage area 19 is a part of the encryption area allocated for electronic money, the capacity is 16 bytes (128 bits), and the size of the unique number information is 8 bytes. Assuming that As shown in FIG. 11, the first recording method divides the first storage area 15 into 8-byte storage areas ER1 and ER2, and at the time of writing, first, the unique number information of the storage area ER1 is stored. The information is transferred to the storage area ER2, and the unique number information to be written next is written to the storage area ER1. With this method, a maximum of two unique number information logs related to the most recently used electronic coupon are stored in the terminal log area in the third storage area 19.

  A second recording technique is shown in FIG. In this method, the terminal log area in the third storage area 19 is divided into a predetermined number (here, 8) of storage areas ER1 to ER8, and a serial number is assigned to each electronic coupon for each mobile phone, and this is made unique. Number information. Therefore, each electronic coupon information given from the electronic coupon issue server 300 to the mobile phone 100 includes unique number information that is issue serial number information given to each electronic coupon. That is, the issue serial number information is handled as unique number information. The electronic coupon issue server 300 performs “payout” so that the issued issue serial number information is not issued repeatedly.

Since the capacity that can be stored in the storage areas ER1 to ER8 shown in FIG. 12 is 2 bytes, the maximum issue number is 2 ¹⁶ = 65536. Further, when storing the unique number information, for example, after shifting the stored contents such as ER1 → ER2 →... → ER8, the unique number information to be written this time is written in the storage area ER1. With this method, up to eight unique number information logs related to the most recently used electronic coupon are stored in the terminal log area in the third storage area 19. In FIG. 12, among the issued electronic coupons having issued serial number information “1” to “4”, the electronic coupons having issued serial number information “2” and “4” have been used. Issued serial number information “2” and “4” are stored in ER1 and ER2.

  A third recording technique is shown in FIG. Also in this method, each electronic coupon information given from the electronic coupon issuing server 300 to the mobile phone 100 includes unique number information which is issuing serial number information given to each electronic coupon. The electronic coupon issue server 300 performs “payout” so that the issued issue serial number information is not issued repeatedly.

In the third recording method, the terminal log areas in the third storage area 19 having a capacity of 16 bytes (128 bits) are used in a line as shown in FIG. In the second recording method, the issue serial number information is stored, but in the third recording method, the bit corresponding to the issue serial number information is set to 1. Specifically, 1 to 16 bits are used as a page, and the next bit to 126 bits are used as a log bit part. In a page from 1 bit to 16 bits, 2 ¹⁶ = 65536 pages can be stored by using the whole as a binary number.

  56 pieces of issued serial number information are written in the current log bit portion for each page. When writing for use of an electronic coupon having issued serial number information after 57 of each page, the log bit part is shifted to the right by 56 bits to increment the page. As a result, the history of the past 57 to 112 can be held, and the maximum issue number is 3.17 million (65536 pages × 56 bits). FIG. 13 shows a log corresponding to the fact that the electronic coupons having the issue sequence number information “2” and “4” are used among the electronic coupons having the issue sequence number information “1” to “4”. 1 is written in the bit part.

  However, it is not possible to log about the use of an electronic coupon having issued serial number information that is two or more pages old. For example, when the mobile phone 100 has an electronic coupon having issued serial number information of 1 to 200, if an electronic coupon having an issued serial number information of 200 is used, an increment of 3 pages is performed. Therefore, it is necessary to write 1 to the log bit part of the issued serial number information 200. Even if an electronic coupon having the issuance serial number information 10 is used after this processing is performed, the log cannot be held in the mobile phone 100. Therefore, it is necessary to take measures such as prompting the user of the mobile phone 100 to use an electronic coupon with a younger issued serial number information.
