Description

  The present invention relates to the technical field of electronic information storage media such as IC chips.

  In short-range wireless communication, an IC card for contactless communication used by being mounted on a mobile terminal has a contact interface for contact communication and a contactless interface for contactless communication via an antenna of the mobile terminal. The non-contact interface is connected to a chip on the mobile terminal side called CLF (Contactless frontend). The CLF is a front end that manages an antenna used for short-range wireless communication, and relays communication between a contactless R / W (Reader / Writer) and a contactless compatible IC card.

  When a portable terminal having a non-contact communication-compatible IC card and a CLF comes close to a non-contact R / W and a communicable distance, an initial communication response is performed between the CLF and the non-contact R / W. By appropriately performing this initial response, communication parameters used by the CLF and the non-contact R / W are set thereafter, and communication between the IC card supporting non-contact communication and the non-contact R / W becomes possible. .

  The CLF requires setting information (information created based on various information such as the corresponding communication protocol and bit rate) of the IC card for contactless communication in order to appropriately perform the initial response. For this reason, the IC card for non-contact communication transmits the setting information to the CLF through the non-contact interface when the communication channel between the IC card for non-contact communication and the CLF is initialized. Then, the CLF manages the received setting information in association with a communication channel with the IC card for contactless communication. Note that the IC card for non-contact communication can transmit setting information to the CLF at an arbitrary timing as long as a communication channel with the CLF has been established. As an example of the transmission timing, Patent Document 1 discloses that setting information is transmitted to the CLF in response to a request from the CLF.

  When the IC card for non-contact communication is equipped with a plurality of applications, the setting information transmitted to the CLF is created by reflecting the information of the application that processes the communication. A method for calculating setting information to be transmitted to the CLF is standardized in a contactless communication-compatible IC card having a plurality of applications (GP Amd.C). In this method, information (Protocol Data) specifying a signal that can be processed by the application is given to each application.

  Further, the user can set the availability and priority of the interface for the application, and a technique related to this is disclosed in Patent Document 2. The IC card for non-contact communication creates setting information reflecting information such as protocol data and priority of the application to be installed. This creation process requires a certain amount of time because it is necessary to scan information of all applications that use the non-contact interface.

  Note that the user can temporarily change the availability and priority of the interface. At this time, the IC card for contactless communication creates setting information reflecting the temporarily changed information, transmits it to the CLF, and asks the CLF to make an initial response based on the setting information. Thereby, communication according to the changed content becomes possible between the non-contact communication compatible IC card and the non-contact R / W.

JP 2012-84156 A JP 2010-218450 A

  Here, communication according to the changed content is completed between the non-contact communication compatible IC card and the non-contact R / W, and then communication is performed between the non-contact communication compatible IC card and the non-contact R / W. In order to perform communication according to the normal contents before the change, the setting information reflecting the normal information is transmitted to the CLF again, and an initial response is made to the CLF with the non-contact R / W. It is necessary to have you.

  However, since it takes a certain amount of time to re-create the setting information in order to transmit the setting information reflecting the normal information to the CLF, for example, a delay in the start of communication when the portable terminal is put on non-contact R / W There is a problem that usability deteriorates. This delay occurs because the CLF waits for the reception of setting information from the non-contact communication compatible IC card when the non-contact communication compatible IC card and the non-contact R / W make an initial response before starting communication.

  Accordingly, the present invention creates and relays setting information reflecting the change of application information temporarily changed for setting information created based on application information related to the application and transmitted to a relay device such as CLF. Even when it is transmitted to the device, the communication setting based on the setting information created based on the application information before the change is made immediately, and a delay occurs in the start of communication with the terminal device such as non-contact R / W. It is an object of the present invention to provide an electronic information storage medium and the like without any problem.

FIG. 3 is a diagram illustrating a configuration example of a UIM card 18. FIG. It is a flowchart which shows an example of the process at the time of the change request by CPU181. 4 is a flowchart illustrating an example of power-on processing by a CPU 181.

  An embodiment for carrying out the present invention will be described with reference to FIG.

  As shown in FIG. 1, the electronic information storage medium 100 includes a memory M, an input receiving unit 103, an application information management unit 104, a setting information creation unit 105, a reading source identification information management unit 106, and a transmission unit 107. The memory M includes a volatile memory 101 and a nonvolatile memory 102. The electronic information storage medium 100 is connected to the relay device 110 and can communicate with the terminal device 120 via the relay device 110.

  The nonvolatile memory 102 stores application information related to applications. The non-volatile memory 102 stores normal setting information that is normal setting information.

  The volatile memory 101 stores temporary setting information that is temporary setting information. Further, the volatile memory 101 temporarily stores at least a part of the application information.

  The input receiving unit 103 receives a temporary change instruction or a permanent change instruction from the user for application information (for example, information indicating priority between applications).

  When the application information management unit 104 receives an instruction to temporarily change the application information, the application information management unit 104 changes the application information temporarily according to the content of the instruction.

  When the application information management unit 104 temporarily changes the application information, the application information before the change on the nonvolatile memory 102 may be copied to the volatile memory 101 and the copied application information may be changed. . Thereby, the application information before the change (that is, normal time) is held in the nonvolatile memory 102, and the application information reflecting the contents of the temporary change is held in the volatile memory 101. It becomes. Alternatively, when the application information is temporarily changed, the application information before the change may be copied to the nonvolatile memory 102, and the copied application information may be changed. As a result, the non-volatile memory 102 holds application information before the change (that is, normal time) and application information reflecting the contents of the temporary change.

  In addition, when an application information permanent change instruction is received for the application information, the application information management unit 104 changes the application information stored in the nonvolatile memory 102 according to the content of the instruction.

  The setting information creation unit 105 creates normal setting information based on the application stored in the nonvolatile memory 102. In addition, the setting information creation unit 105 stores application information in which the contents of the change are temporarily reflected by the application information management unit 104 in the memory M (the volatile memory 101 or the non-volatile memory 102). Based on the application information that reflects the contents of the temporary change, temporary setting information that is temporary setting information is created and stored in the memory M (the volatile memory 101 or the nonvolatile memory 102).

  The read source identification information management unit 106 manages read source identification information. The read source identification information is stored in the memory M (the volatile memory 101 or the non-volatile memory 102). The reading source identification information is information indicating a position where setting information to be transmitted by the transmission unit 107 is stored, and a type, an address, and the like of a memory in which normal setting information or temporary setting information is stored are set. . For example, when the temporary setting information is stored in the volatile memory 101, the reading source identification information management unit 106 sets the address where the temporary setting information on the volatile memory 101 is stored, and the temporary setting information Is stored in the nonvolatile memory 102, an address at which temporary setting information on the nonvolatile memory 102 is stored is set. On the other hand, when the temporary setting information is not stored in either the volatile memory 101 or the nonvolatile memory 102, the address where the normal time setting information is stored in the nonvolatile memory 102 is set.

  Further, the read source identification information management unit 106 sets the address where the normal time setting information in the nonvolatile memory 102 is stored in the read source identification information when a predetermined condition is satisfied. The predetermined condition here refers to, for example, after the power supply to the electronic information storage medium 100 is cut off (for example, the voltage at the power supply terminal becomes less than the predetermined voltage) and the information on the volatile memory 101 is erased. The power supply to the electronic information storage medium 100 is restarted (for example, the voltage at the power supply terminal becomes equal to or higher than a predetermined voltage), the non-contact interface is reset, and the like.

  The transmitting unit 107 transmits the normal setting information or the temporary setting information stored at the position indicated by the reading source identification information to the relay device. For example, when it is detected that the content of the read source identification information has been updated, the transmission unit 107 transmits the normal time setting information or the temporary setting information.

  Next, an operation example of the electronic information storage medium 100 will be described. First, the input receiving unit 103 receives an input requesting to temporarily select a specific application among a plurality of applications mounted on the electronic information storage medium 100 from the user. Next, the application information management unit 104 copies the application information stored in the nonvolatile memory 102 to the volatile memory 101, and changes the application information in response to a request. Next, the setting information creation unit 105 creates temporary setting information based on the application information that has been temporarily changed on the volatile memory 101 and stores the temporary setting information in the volatile memory 101. Next, the read source identification information management unit 106 sets an address where the temporary setting information on the volatile memory 101 is stored as the read source identification information. Next, the transmitting unit 107 transmits the temporary setting information stored at the address indicated by the read source identification information to the relay device 110. Then, after an initial response is made between the relay device 110 and the terminal device 120, and communication (communication with the contents changed temporarily) is made between the electronic information storage medium 100 and the terminal device 120, When power supply to the electronic information storage medium 100 is cut off and power supply to the electronic information storage medium 100 is resumed, the read source identification information management unit 106 stores the read source identification information on the nonvolatile memory 102 as read source identification information. The address where the normal setting information is stored is set. Next, the transmission unit 107 transmits the normal time setting information stored at the address indicated by the read source identification information to the relay device 110. Thereafter, an initial response is made between the relay device 110 and the terminal device 120 based on normal setting information, and communication between the electronic information storage medium 100 and the terminal device 120 (before temporary change is made). Communication (contents at normal time).

  That is, the electronic information storage medium 100 includes a memory M that stores application information related to an application, and is an electronic information storage medium that can communicate with the terminal device 120 via the relay device 110. An example of “means” creates setting information used by the relay device 110 for communication settings with the terminal device 120 based on the application information, stores the setting information in the memory M, and the transmission unit 107 (an example of “transmission means”) When the setting information is transmitted to the relay device at a predetermined timing, and the setting information creation unit 105 is instructed to temporarily change the application information, the setting information creation unit 105 temporarily changes the setting information based on the application information to which the temporary change has been added. Temporary setting information, which is typical setting information, and the application information before the temporary change is made Is stored in the memory M separately from the normal setting information that is the normal setting information created based on the information, and the transmission unit 107, if the temporary setting information is stored in the memory M, the temporary setting information Information is transmitted, and when the temporary setting information is not stored, the normal setting information is transmitted.

  Therefore, according to the electronic information storage medium 100, even when the application information is temporarily changed and the temporary setting information is created and transmitted to the relay device 110, the application information is created based on the application information before the change. Since the normal time setting information is stored in the memory separately from the temporary setting information, the normal time setting information can be transmitted immediately to the relay device 110, and communication settings between the relay device 110 and the terminal device 120 can be made. This is done immediately and there is no delay in the start of communication with the terminal device.

  Next, specific examples corresponding to the above-described embodiments will be described. The embodiment described below is an embodiment when the present invention is applied to an IC chip mounted on a UIM card provided in a portable terminal.

  First, with reference to FIG. 2 etc., the structure and functional outline | summary of the portable terminal 1 which concern on a present Example are demonstrated.

[1. Configuration of mobile terminal 1]
FIG. 2 is a block diagram illustrating a schematic configuration example of the mobile terminal 1 according to the present embodiment. As shown in FIG. 2, the mobile terminal 1 includes a control unit 11, a storage unit 12, a wireless communication unit 13, a display unit 14, an input unit 15, a CLF interface 16a, an IC card interface 16b, a CLF (Contactless frontend) 19, and the like. These components are connected to each other via a bus 17. The mobile terminal 1 includes a battery B and a UIM card 18. The mobile terminal 1 is, for example, a mobile phone, a smartphone, a tablet terminal, or the like.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 12 is configured by a nonvolatile memory such as a flash memory, for example. The ROM or storage unit 12 stores an OS (Operating System) and middleware of the mobile terminal 1. In addition, the storage unit 12 stores an API (Application Program Interface) and an application (hereinafter sometimes referred to as “application”) installed in the mobile terminal 1. The API is an interface for using an operating system function from an application. The application is a program that can be downloaded from a predetermined server, for example.

  The wireless communication unit 13 includes an antenna and controls wireless communication performed with a base station in the mobile communication network. The display unit 14 includes, for example, a touch panel type display panel, and performs display control on the display panel and reception of an operation instruction from the user. The input unit 15 includes an operation button for inputting an operation instruction from the user, and outputs a signal corresponding to the operation button to the control unit 11. The CLF interface 16a serves as an interface between the control unit 11 and the CLF 19, and the IC card interface 16b serves as an interface between the control unit 11 and a UIM (User Identity Module) card 18.

  The UIM card 18 is one of UICCs (Universal Integrated Circuit Cards) which are IC cards, and for example, a contact type IC chip whose function is expanded based on a conventional SIM (Subscriber Identity Module) is mounted.

  The CLF 19 is a non-contact type IC chip that performs non-contact communication defined by the NFC (Near Field Communication) standard, and various types of non-contact R / W (not shown) in the non-contact communication field. It is connected to an antenna for transmitting and receiving signals. Then, when the user places the portable terminal 1 in the non-contact R / W, an initial response is made with the non-contact R / W based on the setting information of the UIM card 18 held in advance. When the initial response is properly completed, the CLF 19 transmits the command transmitted from the contactless R / W to the UIM card 18 via the interface (not shown), and the command received from the UIM card 18 A response is returned to the non-contact R / W. The CLF 19 can be operated by the OS of the mobile terminal 1.

  The battery B is composed of, for example, a lithium ion battery. With the power supplied from the battery B, the control unit 11, the storage unit 12, the wireless communication unit 13, the display unit 14, the input unit 15, the CLF interface 16a, the IC card interface 16b, the CLF 19, and the like of the mobile terminal 1 operate. Note that the battery B can supply power to the UIM card 18 even when the power of the mobile terminal 1 is OFF (provided that the battery B is supplied by the function of the safety protection circuit when the voltage of the battery B falls below a specified voltage ( Discharge) is cut off).

[2. Configuration of IC chip C]
FIG. 3 is a block diagram illustrating a schematic configuration example of the IC chip C mounted on the UIM card 18 according to the present embodiment. As shown in FIG. 3, the IC chip C includes a CPU 181, a RAM 182, a flash memory 183, an I / O circuit 184, and the like, and these components are connected to each other via a bus 185.

  The RAM 182 stores, for example, data temporarily necessary for the function of the OS, middleware, and various applications of the IC chip C to function. Also, temporary temporary setting information and a priority list indicating the priority of the application are stored.

  The flash memory 183 is a nonvolatile memory, and instead, for example, “Electrically Erasable Programmable Read-Only Memory” may be adopted. The flash memory 183 stores, for example, the OS of the IC chip C, middleware, and various applications.

  Further, the flash memory 183 stores data (program, instance, various information) related to the application installed in the UIM card 18 (IC chip C). The application is implemented as a software program that operates on Java (registered trademark) Card. In addition, the flash memory of the present embodiment can be used for credit settlement apps of Company A, Company B and Company C, and the user can change the priority order among credit settlement apps temporarily or permanently, or change the availability of use. Or an input application (for example, a CRS applet) is installed to change the protocol data of the application. The input is accepted as a command word (command APDU (Application Protocol Data Unit)) via the contact interface.

  Further, the flash memory 183 stores normal setting information, a priority list indicating the priority of the application, a use availability list indicating whether the application is available, and reading source identification information.

  Note that the priority list of the flash memory 183 describes information indicating the priority order of credit settlement applications during normal times. On the other hand, the priority list in the RAM 182 describes information indicating the priority order of the credit settlement application when the priority order of the credit settlement application is temporarily changed by the user. When the user makes a credit payment, if the mobile terminal 1 is placed in contactless R / W, the payment is performed by the credit payment application with the highest priority. For this reason, the user sets the priority order of the credit settlement application used at the normal time to be the highest, and when the settlement is temporarily performed by another credit settlement application, It can be set so that the priority order of the credit settlement application is the highest. Then, when payment by another credit payment application is temporarily ended, and the next time the credit payment application is used, the priority order of the credit payment application used at normal time is not changed unless temporarily changed. It becomes the highest, and settlement by the credit settlement application becomes possible.

  The normal setting information stored in the flash memory 183 is based on the contents of the priority list, the contents of the availability list stored in the flash memory 183, the bit rate of TYPE A [ISO-14443-3], and the like. Created. However, another parameter of TYPE A / TYPE B and the collision avoidance response of TYPE F may be included. On the other hand, the temporary setting information stored in the RAM 182 is basically created based on the same information as the normal setting information, but the priority list is based on the contents of the priority list stored in the RAM 182.

  The I / O circuit 184 has eight connection terminals C1 to C8 defined by ISO7816 or the like. For example, the C1 terminal is a power supply terminal, the C2 terminal is a reset terminal, the C3 terminal is a clock terminal, the C5 terminal is a ground terminal, and the C7 terminal is a terminal that performs data communication with the mobile terminal 1. A line that receives power from the CLF 19 is connected to the C1 terminal. The CLF 19 is supplied with electric power from the battery B and electric power from the carrier wave from the non-contact R / W, and is supplied to the IC chip C. However, when there is power supply from both sides, the power from the battery B is given priority. Note that switching from the power supply of the battery B to the power supply by the carrier wave is performed after the supply voltage to the IC chip is OFF.

  The I / O circuit 184 provides a contact interface and a non-contact interface. The contact interface is implemented as a UART (Universal Asynchronous Receiver Transmitter) that supports T = 0 [ISO-7816]. The contactless interface is implemented as SWP (Single Wire Protocol) [ETSI 102.613] supporting HCI (Host Controller Interface) [ETSI (European Telecommunications Standards Institute) 102.622].

  When the CPU 181 receives a command from the CLF 19, the CPU 181 executes a command response process corresponding to the command and responds to the CLF 19 (specifically, response data including a result of the command response process is transmitted to the CLF 19). When the CPU 181 receives a command from the control unit 11, the CPU 181 executes a command response process corresponding to the command and responds to the control unit 11 (specifically, controls data indicating the result of the command response process). To the unit 11.

  Further, as a function of the OS, when the CPU 181 receives a request for temporarily changing the priority list via the input application, the CPU 181 copies the priority list of the flash memory 183 to the RAM 182 and changes the request according to the request. Do. Next, the CPU 181 creates temporary setting information reflecting the contents of the priority list stored in the RAM 182 as an OS function, stores the temporary setting information in the RAM 182, and sets the storage destination address in the read source identification information.

  On the other hand, when the CPU 181 receives a request for permanently changing the priority list or the availability list through the input application as an OS function, the contents of the priority list or the availability list stored in the flash memory 183 Change as required. Next, as a function of the OS, the CPU 181 creates normal setting information reflecting the contents of the priority list or the availability list stored in the flash memory 183, stores the setting information in the flash memory 183, and stores the storage destination address. Is set in the read source identification information.

  Furthermore, as a function of the OS, the CPU 181 sets the address of the normal setting information on the flash memory 183 as the read source identification information when the voltage of the power supply terminal becomes a constant voltage from the voltage level of the ground terminal. To do. For example, after the user of the mobile terminal 1 turns off the power of the mobile terminal 1, the power supply from the battery B is cut off and the voltage of the power supply terminal drops to the voltage level of the ground terminal. When the voltage at the power supply terminal becomes a constant voltage, the address of the normal setting information on the flash memory 183 is set in the read source identification information.

  Furthermore, when the reading source identification information is updated, the CPU 181 transmits the temporary setting information or the normal time setting information stored in the address indicated by the reading source identification information to the CLF 19 via the non-contact interface. Specifically, it is implemented as a driver that processes the HCI protocol layer, and the setting information transmission process is performed as part of the initialization process of the PIPE that is the logical channel of the HCI layer.

[3. Operation of IC chip C]
Next, an operation example of the IC chip C will be described with reference to FIGS. FIG. 4 is a flowchart showing an operation example of a change request process when a request for changing the priority list is received by the input application, and FIG. 5 is a diagram when the power is turned on when the IC chip C is turned on. It is a flowchart which shows the operation example of a process.

  As shown in FIG. 4, in the change request processing, the CPU 181 first determines whether or not a request for changing the priority has been received via the input application (step S101). If the CPU 181 determines that the request for changing the priority is not received (step S101: NO), the CPU 181 ends the process shown in the flowchart. On the other hand, when the CPU 181 determines that the request for changing the priority has been received (step S101: YES), the CPU 181 determines whether the change request is a temporary request (step S102).

  If the CPU 181 determines that the change request is a temporary request (step S102: YES), the CPU 181 updates the priority list in the RAM 182 (step S103). For example, the CPU 181 copies the priority list of the flash memory 183 to the RAM 182 and changes the priority according to the request.

  Next, the CPU 181 creates temporary setting information based on the priority list in the RAM 182 and information on other applications, and stores the temporary setting information in the RAM 182 (step S104).

  Next, the CPU 181 sets the address where the temporary setting information is stored in the reading source identification information (step S105), and proceeds to the processing of step S109.

  On the other hand, if the CPU 181 determines that the change request is not a temporary request (ie, a permanent request) (step S102: NO), the CPU 181 updates the priority list of the flash memory 183 (step S106). ).

  Next, the CPU 181 creates normal setting information based on the priority list of the flash memory 183 and other information related to the application, and stores it in the flash memory 183 (step S107).

  Next, the CPU 181 sets the address where the normal setting information is stored in the reading source identification information (step S108), and proceeds to the processing of step S109.

  Next, the CPU 181 checks the state of the non-contact interface (step S109). Specifically, the CPU 181 operates as a driver that manages an HCI session, and confirms whether a PIPE that performs communication with the non-contact R / W has been established. If it has been established, it is confirmed whether communication is being executed on the PIPE.

  Next, as a result of checking the state of the non-contact interface, the CPU 181 determines whether or not the PIPE initialization process is possible (step S110). Specifically, when the PIPE is not established, the CPU 181 determines that the PIPE initialization process is impossible when the PIPE has been established but the communication is in progress. If the CPU 181 determines that the PIPE initialization process is not possible (step S110: NO), the CPU 181 ends the process shown in the flowchart. Note that, as a result of checking the state of the non-contact interface, if the non-contact interface cannot be used (when SWP communication is not established, including when not electrically connected), the CPU 181 determines that “ It is determined as “NO”. On the other hand, when it is determined that the PIPE initialization process is possible (step S110: YES), the CPU 181 performs the PIPE initialization process (step S111), and ends the process shown in the flowchart. In the initialization processing of PIPE, the CPU 181 transmits temporary setting information on the RAM 182 stored at the address indicated by the read source designation information or normal setting information on the flash memory 183 to the CLF 19.

  Next, an operation example of power-on processing will be described with reference to FIG.

  As shown in FIG. 5, in the power-on process, the CPU 181 first determines whether or not the power is turned on (step S201). For example, when the voltage of the power supply terminal becomes a certain value or more, it is determined that the power is turned on. When the CPU 181 determines that the power is not turned on (step S201: NO), the process shown in the flowchart is terminated. On the other hand, when the CPU 181 determines that the power is turned on (step S201: YES), the CPU 181 determines whether or not the address (that is, the address on the RAM 182) where the temporary setting information is stored is set in the reading source identification information. (Step S202).

  If the CPU 181 determines that the address at which the temporary setting information is stored is not set in the reading source identification information (step S202: NO), the process shown in the flowchart is terminated. On the other hand, if the CPU 181 determines that the address where the temporary setting information is stored is set in the reading source identification information (step S202: YES), then the normal time setting information is stored in the reading source identification information. (That is, the address where the normal time setting information is stored in the flash memory 183) is set (step S203).

  Next, the CPU 181 checks the state of the non-contact interface (step S204). Specifically, the CPU 181 confirms whether the PIPE has been established.

  Next, as a result of checking the state of the non-contact interface, the CPU 181 determines whether or not the PIPE initialization process is possible (step S205). When the CPU 181 determines that the PIPE initialization process is impossible (step S205: NO), the CPU 181 ends the process shown in the flowchart. Note that, as a result of checking the state of the non-contact interface, if the non-contact interface cannot be used (when the SWP communication is not established, including the case where it is not electrically connected), the CPU 181 determines “ It is determined as “NO”. On the other hand, if the CPU 181 determines that the PIPE initialization process is possible (step S205: YES), the CPU 181 then performs the PIPE initialization process (step S206), and ends the process shown in the flowchart. In the initialization process of the PIPE, the CPU 181 transmits the normal setting information on the flash memory 183 stored at the address indicated by the read source designation information to the CLF 19.

  As described above, according to the above-described embodiment, the IC chip C (an example of “electronic information storage medium”) includes the flash memory 183 that stores application information related to an application, and the CLF 19 (an example of “relay device”). Can communicate with a non-contact R / W (an example of a “terminal device”), and the CPU 181 (an example of a “creating unit” and an “transmitting unit”) uses application information including contents such as a priority list. Based on this, setting information for the CLF 19 to make an initial response with non-contact R / W is created, stored in the flash memory 183, and when the power is turned on (an example of “predetermined timing”), Send to CLF19. In addition, when there is an instruction to temporarily change application information such as a priority list, the CPU 181 displays temporary setting information that is temporary setting information based on the application information to which the temporary change has been made. Created and stored in the RAM 182 separately from the normal setting information. When the temporary setting information is stored in the RAM 182, the temporary setting information is transmitted. When the temporary setting information is not stored in the RAM 182, the temporary setting information is stored. The normal time setting information of the flash memory 183 is transmitted.

  Therefore, according to the IC chip C, even when the application information is temporarily changed and the temporary setting information is generated and transmitted to the CLF 19, the normal time setting information generated based on the application information before the change is generated. Is stored in the flash memory 183 separately from the temporary setting information, the normal setting information can be immediately transmitted to the CLF 19, and an initial response is immediately made between the CLF 19 and the non-contact R / W. There is no delay in the start of communication with the contact R / W.

  Further, the flash memory 183 stores read source identification information (an example of “position information”) indicating a position where the setting information to be transmitted to the CLF 19 is stored, and the CPU 181 stores the setting information or the information according to the read source identification information. Send temporary setting information. Therefore, when the setting information is transmitted to the CLF 19, the position where the setting information is stored can be grasped instantaneously, and the time until the setting information is transmitted to the CLF 19 can be shortened.

  The setting information is stored in advance at a predetermined position on the flash memory 183 and the temporary setting information is stored at a predetermined position on the RAM 182. When the CPU 181 transmits the setting information to the CLF 19, the information on the RAM 182 is stored. When temporary setting information is stored at a predetermined position, the temporary setting information is transmitted. On the other hand, when temporary setting information is not stored at a predetermined position on the RAM 182, it is stored at a predetermined position on the flash memory 183. The setting information that has been set may be transmitted. In this case, the processing load for updating the read source identification information can be reduced. In addition to this, if temporary setting information presence / absence information is stored in the flash memory 183 instead of the read source identification information and the CPU 181 stores the temporary setting information at a predetermined position on the RAM 182, the temporary setting information presence / absence is determined. When the information indicating “present” is set in the information, and the temporary setting information is not stored, the information indicating “none” is set in the temporary setting information presence / absence information. When information indicating “present” is set in the temporary setting information presence / absence information, the temporary setting information stored in a predetermined position on the RAM 182 is transmitted, and information indicating “none” is included in the temporary setting information presence / absence information. Is set, the normal time setting information stored in a predetermined position on the flash memory 183 may be transmitted.

  In the above embodiment, the IC chip C has been described as an example of the electronic information storage medium of the present invention. However, the present invention can also be applied to an embedded microchip or the like.
