[0023] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0024] [1. Configuration and Functions of IC Chip 1] First, the configuration and functions of an IC chip 1 according to this embodiment will be described with reference to Fig. 1. The IC chip 1 is an example of an electronic information storage medium of the present invention. The IC chip 1 is mounted on, for example, an IC card such as a credit card, an electronic money card, or a point card, or a mobile device such as a smartphone. In the case of a mobile device such as a smartphone, the IC chip 1 may be mounted on a small IC card that is detachable from the mobile device, or may be mounted on an embedded board as an eUICC (Embedded Universal Integrated Circuit Card) so that it cannot be easily removed or replaced from the mobile device.

[0025] FIG. 1 is a diagram showing an example of a hardware configuration of an IC chip 1. As shown in FIG. 1, the IC chip 1 includes an I / O circuit 11, a random access memory (RAM) 12, a nonvolatile memory (NVM) 13, a read only memory (ROM) 14, a central processing unit (CPU) 15 (an example of a computer), and a coprocessor 16 that performs cryptographic operations. The I / O circuit 11 serves as an interface with an external terminal 2. Note that communication between the IC chip 1 and the external terminal 2 may be non-contact communication or contact communication. In the case of non-contact communication, the IC chip 1 and the external terminal 2 communicate with each other via an antenna (not shown) mounted on an IC card or a mobile device, for example. Note that examples of the external terminal 2 include a loyalty terminal and a payment terminal installed in a store (physical store).

[0026] For example, a flash memory is applied to the NVM 13. The NVM 13 may be an "Electrically Erasable Programmable Read-Only Memory". The NVM 13 or the ROM 14 stores various programs such as an OS (Operating System), middleware, and applications (including the program of the present invention). FIG. 2 is a diagram showing an example of the software configuration of the IC chip 1. In the example of FIG. 2, the applications that run on the OS include a Proximity Payment System Environment (PPSE) application and a credit card payment application. The PPSE application includes File Control Information (FCI) and a POI information list. The FCI includes a Directory Entry, a Selection Data Object List (SDOL), and a Terminal Categories supported List. Here, the Directory Entry indicates a credit card payment application. The applications that run on the OS may include a transportation payment application.

[0027] The FCI and the POI information list are stored in the NVM 13 when the PPSE application is installed in the IC chip 1. After the PPSE application is installed in the IC chip 1, when a SELECT command for selecting the PPSE application from the external terminal 2 is received via the I / O circuit 11, an FCI including both or either one of the SDOL and the Terminal Categories supported List is returned to the external terminal 2 via the I / O circuit 11 as a response to the SELECT command. Note that the SDOL and the Terminal Categories supported List are publicly known from Non-Patent Document 1 and the like, and therefore detailed explanations thereof will be omitted.

[0028] The POI information list is, for example, a record for reading out and recording a value value in association with an identifier of the POI information. Here, the POI information is, for example, store-specific information associated with each store or each store group. A store group refers to a plurality of stores (for example, chain stores such as convenience stores, coffee shops, or restaurants) with different installation locations (addresses). The ID of the POI information is different for each store. Alternatively, the ID of the POI information may be different for each store group (for example, the same ID is assigned to the same convenience store). The value is data having a value that allows a user to receive a unique service from a store, and is a value that increases according to the frequency of the user's use of the store. The value can also be used as a transaction record between the user and the store.

[0029] FIG. 3 is a diagram showing an example of a POI information list. The POI information list shown in FIG. 3 includes, as identifiers of POI information, a POI Information ID and an Additional POI Information data object ID. The POI Information ID is an identifier that requires an application to EMV (registered trademark) and is given to, for example, a chain store. On the other hand, the Additional POI Information data object ID is an identifier that does not require an application to EMV (registered trademark) and is given to, for example, an independently-run store. In the example of FIG. 3, a store visit point and a number of visits are associated with each ID.

[0030] Here, the store visit points are an example of a first value indicating the number of points that increases by a predetermined number (an example of a first predetermined value) each time the user visits a store. For example, the store visit points are available to the user when paying for a product or service (i.e., available for settlement). That is, the user can receive a special service according to the store visit points. The predetermined points may be different for each store or each store group. The store visit points are an example of a second value (a value different from the first value) indicating the number of store visits that increases by 1 (an example of a second predetermined value) each time the user visits a store. For example, when the number of store visits reaches a threshold value, the user can receive a special benefit such as a gift from the store. That is, the user can receive a special service according to the number of store visits. Note that the above identifier and value may not be recorded in the POI information list at the time the PPSE application is installed. Then, when the user visits a store, the identifier and value of the POI information associated with the store are recorded in the POI information list.

[0031] The CPU 15 (an example of a computer) executes the program of the present invention stored in the NVM 13, thereby functioning as a receiving means, a determining means, an adding means, and the like in the present invention. More specifically, the CPU 15 receives an SPI command (an example of a command) in which data including an identifier of POI information associated with the store is set from the external terminal 2 installed in the store, via the I / O circuit 11. Here, the terminal category of the external terminal 2 may be set in the SPI command together with the data including the identifier of the POI information. FIG. 4 is a diagram showing an example of a format of the SPI command. The SPI command is composed of, for example, a command APDU (Application Protocol Data Unit) defined in ISO / IEC 7816. As shown in FIG. 4, the SPI command is composed of a header portion composed of CLA, INS, P1, and P2, and a body portion composed of Lc, Data, and Le. For example, a TLV value is set in Data.

[0032] FIG. 5 is a diagram showing an example of the format of a TLV value set in Data of an SPI command. Value in the TLV value shown in FIG. 5 includes SDOL requested data object values, Terminal Category, and Additional POI Information data objects. Here, when "xxxx" indicating Terminal Category is "0002", it indicates that the external terminal 2 is a royalty terminal. SDOL requested data object values ​​and Additional POI Information data objects are each an example of data including an identifier of POI information. These data include the above-mentioned predetermined points (predetermined value to be added) in association with the identifier of POI information. For example, a predetermined value V1 of length L1 is associated with ID1 of POI Information (or Additional POI Information data objects). Note that it is sufficient for Data of the SPI command to include an identifier of one piece of POI information.

[0033] The CPU 15 judges whether or not the identifier of the POI information included in the data set in the received SPI command (e.g., SDOL requested data object values) is recorded in the POI information list. If the CPU 15 judges that the identifier of the POI information included in the set data is recorded in the POI information list, the CPU 15 adds a predetermined value to the value value associated with the identifier of the POI information in the POI information list. For example, the CPU 15 adds a predetermined value (e.g., the above-mentioned predetermined points) included in the data set in the SPI command to a value value (e.g., store visit points) associated with the identifier of the POI information included in the data set in the SPI command. At this time, the CPU 15 may add 1 to the value value (e.g., the number of store visits) associated with the identifier of the POI information included in the data set in the SPI command.

[0034] Alternatively, the CPU 15 may determine whether or not the identifier of the POI information included in the data set in the received SPI command is recorded in the POI information list, and may determine whether or not the terminal category set in the SPI command indicates a terminal category predetermined in the IC chip 1. Here, "0002" (i.e., a loyalty terminal) may be set as the terminal category predetermined in the IC chip 1, which is managed, for example, by a PPSE application. In this case, when the CPU 15 determines that the identifier of the POI information included in the set data is recorded in the POI information list and that the set terminal category indicates a terminal category predetermined in the IC chip 1, it adds a predetermined value to the value value associated with the identifier of the POI information in the POI information list. This makes it possible to appropriately control whether or not to increase the value value according to the terminal category of the external terminal 2 that communicates with the IC chip 1. In this case, the CPU 15 may also add the predetermined points to the store visit points and add 1 to the number of store visits.

[0035] On the other hand, when the CPU 15 determines that the identifier of the POI information included in the data set in the SPI command is not recorded in the POI information list, it adds the identifier of the POI information included in the data to the POI information list and records a value in association with the identifier of the added POI information. Alternatively, when the CPU 15 determines that the identifier of the POI information included in the data set in the SPI command is not recorded in the POI information list and determines that the set terminal category indicates a terminal category predetermined in the IC chip 1, it may add the identifier of the POI information included in the data to the POI information list and record a value in association with the identifier of the POI information.

[0036] Then, when the CPU 15 receives a READ RECORD command (an example of another command) including an identifier of POI information associated with a store from the external terminal 2 via the I / O circuit 11, the CPU 15 reads out a value value associated with the identifier of the POI information included in the READ RECORD command in the POI information list, and returns a response including the read value value to the external terminal 2 via the I / O circuit 11. This allows the user to receive a special service from the store according to the value.

[0037] [2. Operation during communication between IC chip 1 and external terminal 2] Next, with reference to Fig. 6, an operation during communication between the IC chip 1 according to this embodiment and the external terminal 2 will be described. Fig. 6 is a sequence diagram showing an example of the operation during communication between the IC chip 1 and the external terminal 2. For example, when a user carrying an IC card equipped with the IC chip 1 visits a store and holds the IC card over (or inserts) a reader / writer of the external terminal 2 installed at the cash register when paying for a product or service, communication between the IC chip 1 and the external terminal 2 is started.

[0038] The process shown in Fig. 6 is started after the end of an initial response sequence at the start of communication between the IC chip 1 and the external terminal 2. In the initial response sequence, an initial response including communication parameters (e.g., Answer to reset or Answer to request) is transmitted from the IC chip 1 to the external terminal 2. Then, when the process shown in Fig. 6 is started, the external terminal 2 transmits a SELECT command for selecting a PPSE application to the IC chip 1 (step S1).

[0039] Next, when the IC chip 1 receives the SELECT command from the external terminal 2, it selects a PPSE application (step S2) and transmits a response to the SELECT command to the external terminal 2 (step S3). The response contains an FCI including the SDOL and the like described above. Next, when the external terminal 2 receives the response from the IC chip 1, it transmits to the IC chip 1 an SPI command in which data including an identifier of POI information associated with the store according to the FCI contained in the response and a terminal category are set (step S4).

[0040] Next, when the IC chip 1 receives the SPI command from the external terminal 2, it determines whether or not the terminal category included in the SPI command indicates a terminal category predetermined in the IC chip 1 (step S5). If it is determined that the terminal category indicates a terminal category predetermined in the IC chip 1 (i.e., the external terminal 2 is a loyalty terminal) (step S5: YES), the process proceeds to step S6. On the other hand, if it is determined that the terminal category does not indicate a terminal category predetermined in the IC chip 1 (step S5: NO), the process proceeds to step S9.

[0041] In step S6, the IC chip 1 determines whether or not the identifier of the POI information included in the received SPI command is recorded in the POI information list. If it is determined that the identifier of the POI information is not recorded in the POI information list (step S6: NO), the process proceeds to step S7. On the other hand, if it is determined that the identifier of the POI information is recorded in the POI information list (step S6: YES), the process proceeds to step S8.

[0042] In step S7, the IC chip 1 adds the identifier of the POI information included in the SPI command to the POI information list, records a value (e.g., store visit points and number of visits) in association with the identifier of the added POI information, and proceeds to step S9. Meanwhile, in step S8, the IC chip 1 adds a predetermined value to the value associated with the identifier of the POI information in the POI information list, and proceeds to step S9. For example, the IC chip 1 adds the predetermined points to the store visit points and adds 1 to the number of visits.

[0043] In step S9, the IC chip 1 transmits a response in which an FCI including a Directory Entry indicating a credit payment application is set to the external terminal 2. Next, when the external terminal 2 receives the response from the IC chip 1, it transmits a SELECT command to the IC chip 1 to select a credit payment application according to the FCI included in the response (step S10). Next, when the IC chip 1 receives the SELECT command from the external terminal 2, it selects a credit payment application (step S11) and transmits a response to the SELECT command to the external terminal 2 (step S12). This allows the payment process to be executed between the IC chip 1 and the external terminal 2.

[0044] As described above, according to the above embodiment, when the IC chip 1 receives from the external terminal 2 a POI command in which data including an identifier of POI information associated with a store is set, the IC chip 1 determines whether or not the identifier of the POI information is recorded in the POI information list, and if it determines that the identifier of the POI information is recorded in the POI information list, it adds a predetermined value to the value associated with the identifier of the POI information in the POI information list, so that it is possible to readably record a value value according to the frequency of store use by the user of the IC chip 1. This allows the user to receive special services as a preferred customer from frequently used stores. [Explanation of symbols]
