The best mode for carrying out the invention will be described using various embodiments (first embodiment).
A first embodiment of the present invention will be described below with reference to FIGS. In FIG. 1 showing the configuration of the entire product purchasing system, the system of the present embodiment includes a register 11, a mobile phone device 12, an IC tag 13 housed in the mobile phone device 12, a mobile phone device 12 and a base station 14. And an electronic money sales center 15 that performs communication. As shown in FIG. 2, the cellular phone device 12 has a slot 16 a for accommodating an IC tag 13 (having the same external shape as an IC card) on the bottom side of the case 16. When the IC tag 13 is housed in the mobile phone device 12, the IC tag 13 is connected to the internal electrical configuration by the contact 13a disposed on the surface.

  The cellular phone device 12 includes a telephone unit 12a for performing the original function of the cellular phone device, and the telephone unit 12a schematically includes an RF unit 17 for communicating with the base station 14 in the 800 MHz band, for example. , And a control unit 18 mainly composed of a microcomputer and a power source unit 100 for supplying operation power to them.

  On the other hand, the IC tag 13 is similarly provided with a control unit 19, which is mainly composed of a microcomputer, a memory (storage means) 20 for storing communication data, a receiving system 21 and a transmitting system 22 for communication. In the reception system 21 and the transmission system 22, the control unit 19 communicates with the control unit 23 housed on the register 11 side, for example, by a radio signal (air propagation signal) via the transmission system 24 and the reception system 25. It is the structure for performing.

  Further, the IC tag 13 includes a power generation unit 26. The power generation unit 26 operates the control unit 19 and the like by receiving a signal transmitted from the transmission system 24 on the register 11 side in a system different from the reception system 21 and performing low-pass filtering and smoothing. Electricity is created and supplied.

  As will be described later, the power supply unit 100 of the telephone unit 12a is connected to the IC tag via the contact 13a only when the control unit 18 of the telephone unit 12a performs a data writing process on the memory 20 of the IC tag 13. 13 is also supplied with power for operation.

  Next, the operation of this embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing processing when the user of the system purchases electronic money using the mobile phone device 12 before the product purchase system is used. The user first calls a telephone number of an electronic money sales center (hereinafter referred to as sales center) 15 (step A1). Then, data is downloaded to the mobile phone device 12 from a server on the sales center 15 side (for example, a Web server on the Internet), and a screen for purchasing electronic money is displayed on the display 12b of the mobile phone device 12. Is displayed (step A2).

Subsequently, when the user appropriately selects the denomination of electronic money to be purchased (step A3), when purchasing the selected ticket (step A4, “YES”), the control unit 18 of the mobile phone device 12 has already started. Once the content is confirmed by the user (step A5). And when a user chooses to purchase again (Step A6, "YES"), control part 18 is
The RF unit 17 notifies the sales center 15 to that effect (step A7).

  On the other hand, if the user has not selected to purchase electronic money in any of steps A4 and A6, the control unit 18 causes the user to confirm whether or not to cancel the purchase (step A10). Then, if the user cancels the purchase (“YES”), the process is terminated, and if the user continues the process for purchasing (“NO”), the process returns to step A2.

  Further, when electronic money purchase is notified to the sales center 15 in step A7, purchase confirmation information (including electronic money and security information as necessary) is returned from the sales center 15 (step A8). . Then, the control unit 18 transfers electronic money (and security information as necessary) to the control unit 19 of the IC tag 13 via the contact 13a (and a data buffer (not shown)), and the transferred information data is stored in the memory 20. (Step A9), the process is terminated. This end of purchase is referred to as deposit. When the data writing process in step A9 is performed, as described above, the power supply unit 100 of the telephone unit 12a supplies operation power to the IC tag 13 side.

  Here, electronic money is virtual money that replaces banknotes and coins, but its value is handled in the same way as actual money, but it is not limited to being circulated everywhere, but only at specific stores. This includes items that can be used as substitutes for gift certificates. In this way, any form may be used as long as it is electronic money supplied from an outside business such as a bank which issues electronic money and maintains its credit. Further, for example, when the denomination is limited, the denomination information and the actual sales price after deducting the discount amount are included.

  The electronic money purchase price may be, for example, charging the communication fee at that time by accessing the server of the sales center 15, or registering the bank account number in the sales center 15 and automatically debiting it. The user may make a direct transfer at a bank, a post office, a convenience store, or the like.

  Further, the IC tag 13 includes a power generation unit 26. The power generation unit 26 operates the control unit 19 and the like by receiving a signal transmitted from the transmission system 24 on the register 11 side in a system different from the reception system 21 and performing low-pass filtering and smoothing. Electricity is created and supplied.

  As described above, when electronic money information corresponding to the purchased amount is written in the memory 20 of the IC tag 13 housed in the mobile phone device 12 possessed by the user or when the purchased amount is increased, the user Carrying the mobile phone device 12 to the intended store, the product information is first read by the mobile phone device 12.

  FIG. 4 is a diagram showing a communication sequence performed between the register 11 and the IC tag 13 when the user carrying the mobile phone device 12 passes through the register 11 installed in the store. The register 11 waits until a response is returned from the IC tag 13 while intermittently transmitting an activation signal to the outside. The activation signal is not a signal modulated for transmitting some data or the like, but is merely a radio wave signal transmitted for supplying operation power to the internal circuit of the IC tag 13. In this case, the register 11 is not necessarily a physical register, but includes a register such as a gate type that the purchaser cannot recognize as a general register. Indicates the item that performs the checkout work to reduce the money. Therefore, it generally has a function of holding or transmitting merchandise information and a function of confirming that payment has been made reliably.

When the purchaser (user) approaches the register 11 and the IC tag 13 in the mobile phone device 12 receives the activation signal, the power generation unit 26 generates an operation power supply by the activation signal, and the control unit 19 or the like. To supply. Then, the control unit 19 is activated, reads the product information before settlement and the electronic money balance stored in the memory 20, and transmits information to be transmitted to the register 11 side.

  The control unit 23 of the register 11 that has received the product information before settlement and the electronic money reads the unsettled product information and confirms the balance of the electronic money. If the balance is possible to purchase all the products, the control unit 23 performs settlement to reduce the electronic money balance by the purchase amount, and the balance is insufficient to purchase all the products. If this is the case, a message indicating that payment cannot be made is displayed. Thus, since the IC tag 13 handles electronic money like money, the security level is generally high. The stored merchandise information is generally also security, but it is general to maintain a security level higher than that.

  Furthermore, while it is common for merchandise information to be erased by buyers, electronic money is generally designed to prevent purchasers from operating freely. Or it is common to divide virtually.

  The product IC tag can have the same configuration as the IC tag 13. The communication between the product IC tag and the IC tag 13 may take either initiative. In this case, the product tag may be a product tag or a product built in the package, or a product tag that is connected to the product and can be reused after removal, or may be provided on a storefront label. Absent. It should be noted that the product IC tag generally does not require the same level of security as the IC tag 13 described above.

  The product information read here is a product to be purchased, and is read from a tag attached to the product using the mobile phone device 12.

  The product information in the transmission means may have all the information of the product tag, but in aggregation, information such as how to use the product is information necessary only for the purchaser, so checkout and sales management It is common to send only product information necessary for.

  Similarly, the only information that is useful for the user to store is the product information that has been settled after payment, and only the information that can be used by the purchaser and the purchase confirmation information. In general, only product information is used as product information at the time of storage.

  In this way, product information includes not only information necessary for checkout and sales management, such as price, product name or product code, but also information that can be used by the purchaser such as taste, calories, expiration date, etc. Is preferred. Further, for security use, it is preferable to include purchase confirmation information such as purchase date / time, settlement date / time and amount. Such product information is stored in the memory 20. In addition, it is preferable that the product information includes information for distinguishing product information related to a product before settlement and product information that has been settled.

  In this case, software that is convenient for using the product information, such as a calorie calculation function, may be added to the mobile phone device 12 or the IC tag 13.

  In the communication sequence shown in FIG. 4, once the user writes electronic money into the IC tag 13 according to the flow shown in FIG. 3, the IC tag 13 is removed from the cellular phone device 12, and the user carries only the IC tag 13 and registers. It goes without saying that communication is performed in exactly the same manner even when passing 11.

  Further, the register 11 performs payment using the balance of the merchandise information and the electronic money, a process of subtracting the settlement amount from the IC tag 13 inside the mobile phone device 12, and the settlement of the merchandise information from the unpaid merchandise information. The settlement process for changing to the finished product information is performed by the control unit 18 of the mobile phone device 12 changing the memory 20 of the IC tag 13.

  In this case, since the settlement process has the same effect as the exchange of cash, special consideration is necessary for security. In addition to communication encryption and the like so as not to cause an accident, the IC tag 13 inside the mobile phone device 12 The consistency of the electronic money balance inside the electronic money and the balance of the electronic money recognized by the register 11 needs to be reliably guaranteed by a return signal or the like.

  As described above, according to the present embodiment, the IC tag 13 is accommodated in the mobile phone device 12, and the IC tag 13 is supplied with the operation power by the activation signal transmitted from the register 11. 11 is configured to be able to communicate with 11.

  In addition, when the user acquires electronic money by communicating with the sales center 15 using the mobile phone device 12, the control unit 18 of the mobile phone device 12 writes the electronic money in the memory 20 of the IC tag 13. .

  Further, when the user takes in the product information in advance and settles it using the electronic money corresponding to the register 11 or the like, the control unit 18 of the mobile phone device 12 writes the electronic money in the memory 20 of the IC tag 13.

  Therefore, the user does not have to wait for a long time like waiting for a register in order to purchase a product as in the prior art, and can easily use the product. In addition, even when the cellular phone device 12 is not turned on, the IC tag 13 can operate independently by receiving the operation power supplied from the activation signal transmitted from the register 11, so that convenience is improved. In addition, battery consumption of the mobile phone device 12 can be suppressed. Furthermore, since the product information that has been settled can be automatically retained after the settlement, it is possible to easily track the record when lost in addition to the expiration date management, calorie management, electronic household account book. For this purpose, it is preferable to leave the IC tag 13 with a mechanism that makes correction impossible or difficult, or leaves a correction history.

  As described above, it is preferable to provide the IC tag 13 with a security function. However, the security function may be a single function or a function using a mobile phone. It is also possible to provide a security function for a part or all of the storage means, and for the security function, various methods such as fingerprint authentication method and password can be adopted. It is common to change by function.

  Then, the control unit 48 of the communication device 47 reads the electronic money data from the memory 45 of the memory card 44 and writes the data to the memory 20 of the IC tag 13. Thereafter, as in the first embodiment, when the user carrying the communication device 47 uses the register 11, communication is performed between the register 11 and the IC tag 13.

  As described above, according to the seventh embodiment, when the user acquires electronic money data by communicating with the sales center 15 using the mobile phone device 43, the data acquired by the mobile phone device 43 is written to the memory card 44. The user uses the register 11 with the memory card 44 stored in the communication device 47. Therefore, the same effect as the first embodiment can be obtained.

(Eighth embodiment)
Only the differences from the first embodiment will be described below. FIG. 13 is an example in which usable money amount information such as a facility is written as electronic money on the IC tag 13 in the first embodiment, such as a prepaid card, and the user passes through the register 11. In this example, the usage amount is subtracted every time and the data in the memory 20 of the IC tag 13 is rewritten. In this case, the electronic money includes security information in order to improve security by rewriting data on the IC tag 13 side.

  That is, when the user approaches the register 11 and the IC tag 13 in the mobile phone device 12 receives the activation signal, the control unit 19 is activated and reads the security information stored in the memory 20 and transmits it to the register 11 side. To do. The control unit 23 of the register 11 that has received the security information transmits a confirmation response to the IC tag 13 side after confirming whether the security information is appropriate (that is, used appropriately). The IC tag 13 that has received the confirmation response reads the available amount information stored in the memory 20 and transmits it to the register 11 side.

  The control unit 23 of the register 11 that has received the available amount information subtracts the current used amount from the available amount and transmits the remaining amount information to the IC tag 13 side. Also, in this case, if the received available amount is less than the current amount, the response indicating that it cannot be used is returned to the IC tag 13, and the user passes the ticket gate with the gate closed. Is prohibited.

  The IC tag 13 that has received the remaining amount information transmits a reception response to the register 11 side when the information is written and stored in the memory 20. And the control part 23 of the register | resistor 11 opens a gate of a ticket gate, and permits passage of a user.

  As described above, according to the eighth embodiment, the present invention can be similarly applied even when the amount of money information that can be used by the IC tag 13 is rewritten like a prepaid card.

(Ninth embodiment)
Only the differences from the first embodiment will be described below. The register 11 directly receives the product information before settlement from the product IC tag attached to the product or the product container. The communication between the product IC tag and the register 11 may take either initiative. In this case, the product tag may be a product built into the product or its package, or a product tag that is connected to the product and can be reused after removal after payment. It should be noted that the product IC tag generally does not require the same level of security as the IC tag 13 described above.

  In this state, the register 11 receives the balance of electronic money from the IC tag 13. Then, the control unit 23 of the register 11 confirms the balance of electronic money. If the balance is possible to purchase all the products, the control unit 23 performs settlement to reduce the electronic money balance by the purchase amount, and the balance is insufficient to purchase all the products. In this case, the product information is transmitted to the IC tag 13 at the same time as or after the display indicating that the payment cannot be made. Thus, since the IC tag 13 handles electronic money like money, the security level is generally high. The product information to be sent is only the information that can be used by the purchaser and the purchase confirmation information that is stored after the settlement. It is common to send as much product information as possible.

  In the communication sequence shown in FIG. 14, once the user writes electronic money in the IC tag 13 according to the flow shown in FIG. 3, the IC tag 13 is removed from the mobile phone device 12, and the user carries only the IC tag 13 and registers. It goes without saying that communication is performed in exactly the same manner even when passing 11.

  Further, the register 11 performs payment using the balance of the product information and the electronic money, a process of subtracting the payment amount from the IC tag 13 in the mobile phone device 12, and a process of transmitting the settled product information The product information receiving means is received by the IC tag 13 by the control unit 18 of the mobile phone device 12 changing the memory 20 of the IC tag 13.

  In this case, since the settlement process has the same effect as the exchange of cash, special consideration is necessary for security. In addition to communication encryption and the like so as not to cause an accident, the IC tag 13 inside the mobile phone device 12 The consistency of the electronic money balance inside the electronic money and the balance of the electronic money recognized by the register 11 needs to be reliably guaranteed by a return signal or the like. Therefore, it is common to change the product information and the security level even if simultaneous transmission and reception are performed.

  As described above, according to the ninth embodiment, the IC tag 13 is accommodated in the mobile phone device 12, and the IC tag 13 is supplied with operating power by the activation signal transmitted from the register 11. The communication with the register 11 is configured to be possible.

  Further, unlike the first embodiment, the memory 20 stored in the IC tag 13 is product information that has been settled, and only information that can be used by the purchaser and purchase confirmation information. Therefore, the memory capacity can be reduced.

(Tenth embodiment)
Only the differences from the first embodiment will be described below. FIG. 15 is an example in which usable money amount information such as a facility is written as electronic money on the IC tag 13 in the first embodiment, for example, as a prepaid card, and the user passes through the register 11. In this example, the usage amount is subtracted every time and the data in the memory 20 of the IC tag 13 is rewritten. In this case, the electronic money includes security information in order to improve security by rewriting data on the IC tag 13 side.

  That is, when the user approaches the register 11 and the IC tag 13 in the mobile phone device 12 receives the activation signal, the control unit 19 is activated and reads the security information stored in the memory 20 and transmits it to the register 11 side. To do. The control unit 23 of the register 11 that has received the security information transmits a confirmation response to the IC tag 13 side after confirming whether the security information is appropriate (that is, used appropriately). The IC tag 13 that has received the confirmation response reads the available amount information stored in the memory 20 and transmits it to the register 11 side.

  The control unit 23 of the register 11 that has received the available amount information subtracts the current used amount from the available amount and transmits the remaining amount information to the IC tag 13 side. Also, in this case, if the received available amount is less than the current amount, the response indicating that it cannot be used is returned to the IC tag 13, and the user passes the ticket gate with the gate closed. Is prohibited.

  The IC tag 13 that has received the remaining amount information transmits a reception response to the register 11 side when the information is written and stored in the memory 20. And the control part 23 of the register | resistor 11 opens a gate of a ticket gate, and permits passage of a user.

  As described above, according to the tenth embodiment, the present invention can be similarly applied even when the amount of money information that can be used by the IC tag 13 is rewritten like a prepaid card.

  The present invention is not limited to the embodiments described above, and the following modifications or expansions are possible. The operation power supply for the IC tag 13 may be supplied in the form of a logical sum of the power generation unit 26 and the power supply unit 100. For example, in the first embodiment, when the power of the mobile phone device 12 is supplied when passing through the register 11, the power supply unit 100 supplies the operation power to the IC tag 13. Also good.

  If configured in this way, the communication distance between the register 11 and the mobile phone device 12 can be further increased, so that the user takes the mobile phone device 12 out of a pocket or bag and brings it close to the register 11. Therefore, it can be used as it is, and convenience can be improved.

When the electronic money is a ski resort coupon, the electronic money ID information is transmitted to the register 11 side together with the usage count information, and the information is stored only within the valid period of the coupon ticket on the register 11 side. deep. Then, every time the user passes through the register 11, the usage count information stored on the register 11 side may be decremented. Alternatively, the contents of the memory 20 may be rewritten every time on the ID tag 13 side as in the eleventh embodiment. In addition, for 2-day tickets, 3-day tickets, etc. where the use date is not specified in advance,
The same processing may be performed.

  In step B9 of the second embodiment, in the mobile phone system that cannot perform the call and the data communication in parallel, the ticket purchase information is transmitted by performing the data communication immediately after the end of the call with the operator. You can do it. The air propagation signal signal is not limited to a radio wave signal, but may be a magnetic signal or the like. The mobile phone device also includes a PHS (Personal Handyphone System).

  The present invention relates to a merchandise purchasing system using electronic money, which is a virtual currency value, using a mobile phone in various retail stores such as convenience stores and supermarkets that are mainly self-service.
