Description

  The present invention relates to a technique for using electronic value in a mobile communication terminal such as a mobile phone.

  Mobile phones that can use electronic value such as electronic money have become widespread. In a mobile phone that can use electronic value, payment related to goods and services can be performed by a simple operation of holding the terminal over a reader at the store.

By the way, since the electronic value has a monetary value, it is naturally inconvenient if it is used without permission by another person or stolen by a reader or the like. For this reason, such a cellular phone is generally provided with a function for locking and releasing a function using electronic value. As a method for releasing the lock, there is a method for performing fingerprint authentication in addition to a method for inputting a personal identification number or the like (see, for example, Patent Document 1).

These three axes are hereinafter referred to as “x axis”, “y axis”, and “z axis”, respectively. The gyro sensor 57b detects a change in angular velocity in the x-axis, y-axis, and z-axis directions. Signals output by these sensors are supplied to the control unit 51 as motion signals representing the movement of the mobile communication terminal 50 (movement and rotation in the x-axis, y-axis, and z-axis directions).

  Here, the contents of data stored in the mobile communication terminal 50 will be described. The ROM 51b stores some programs in advance. Hereinafter, this is referred to as a “preinstalled program”. Specifically, the preinstalled programs are programs of a multitask operating system (hereinafter referred to as “multitask OS”), a Java (registered trademark) platform, and a native application. To outline these programs, first, the multitasking OS is an operating system that supports various functions such as allocation of virtual memory space necessary to realize pseudo-parallel execution of multiple tasks by TSS (Time-Sharing System). System. The Java platform is a program group described according to a CDC (Connected Device Configuration) which is a configuration for realizing a Java execution environment 514 described later in a portable device equipped with a multitasking OS.

This Java application is created by a content provider or a communication carrier, stored in a server device of the Internet 10, etc., and is appropriately downloaded from these server devices in response to a request from the mobile communication terminal 50.

  FIG. 4 is a diagram showing a logical configuration of each unit realized in the control unit 51 of the mobile communication terminal 50 by executing various programs in the ROM 51b and the EEPROM 51d. As shown in the figure, in the mobile communication terminal 50 that executes various programs, a browser 512, a mailer 513, and a Java execution environment 514 are realized on the OS 511, and the EEPROM 51d includes a first storage 515 and a second storage 516. And are secured.

Are realized.

  The Java execution environment 514 is realized by the Java platform in the ROM 51b. The Java execution environment 514 includes a class library 517, a JVM (Java Virtual Machine) 518, and a JAM (Java Application Manager) 519. The class library 517 is a combination of program modules (classes) having specific functions in one file. The JVM 518 is a Java execution environment optimized for the above-described CDC, and has a function of interpreting and executing bytecode provided as a Java application. The JAM 519 has a function of managing download, installation, activation / termination, and the like of Java applications.

  The first storage 515 is an area for storing Java applications (Jar files and ADFs) downloaded under the management of the JAM 519. The second storage 516 is an area for storing data generated when the Java application is executed after the end thereof, and an individual storage area is assigned to each installed Java application. . The data in the storage area allocated to a certain Java application can be rewritten only while the Java application is being executed, and another Java application cannot be rewritten.

  The Java application includes an application that manages the lock and release of the electronic payment function. This application is hereinafter referred to as “management application”. The storage area allocated for the management application stores a pattern data file and a history data file. The contents of these data files are as follows.

  FIG. 5 is a diagram conceptually showing the pattern data file. The pattern data file includes a plurality of pieces of pattern information in which patterns of time change (that is, position fluctuation) of movement of the mobile communication terminal 50 are described by acceleration and angle. Each pattern information represents a different pattern of positional variation. In the present embodiment, it is assumed that there are five types of pattern information A, B, C, D, and E as shown in FIG. The pattern information stored as the pattern data file represents a typical pattern when the user holds the mobile communication terminal 50 over the reading terminal 40, and is stored in the EEPROM 51d in advance. In the figure, only time change of acceleration in one direction is shown and used as pattern information. However, the actual pattern information shows the change in acceleration and angle in the x-axis, y-axis, and z-axis directions described above. Represents. The same applies to other figures shown as pattern information hereinafter.

  Further, each pattern information does not represent one specific position variation but represents a type of position variation similar to the specific position variation. Specifically, as shown in FIG. 6, a deviation (deviation) from the position fluctuation is provided for a specific position fluctuation indicated by the curve A, and all the position fluctuations included in the range of the deviation are obtained. It is represented as one pattern. That is, the pattern information includes “position variation information” representing a specific position variation and “deviation information” representing a deviation from the position variation represented by the position variation information.

  The history data file represents a history of position fluctuations detected by the motion detection unit 57. In the history data file, when the position variation detected by the motion detection unit 57 corresponds to the pattern represented by the pattern information stored as the pattern data file described above, this is stored as a history. In the history data file, whether or not the position information corresponding to the pattern information stored as the pattern data file has been detected by the motion detection unit 57 and then the payment information stored in the IC chip unit 56 has been read or written. Are also stored together.

  FIG. 7 is a diagram conceptually showing a history data file, and shows a history of position variation as a table composed of a plurality of records. For example, the record in the first row shown in the figure corresponds to the pattern represented by the pattern information A in which the detected position variation is represented. At this time, the payment information stored in the IC chip unit 56 is read and written. It represents that. The record in the second row shown in the figure corresponds to the pattern represented by the pattern information C in which the detected position variation is represented. At this time, the payment information stored in the IC chip unit 56 is read and written. It means that there was no.

The configuration of the payment system 100 is as described above. Next, processing executed by the mobile communication terminal 50 in order to use the payment system 100 will be described.
The control unit 51 of the mobile communication terminal 50 executes the OS 511 at startup. After executing the OS 511, the control unit 51 activates a predetermined application by executing other necessary programs. At this time, the control unit 51 activates the management application described above.

  FIG. 8 is a flowchart showing processing executed by the control unit 51 of the mobile communication terminal 50 when the management application is activated. If it demonstrates along the figure, the control part 51 of the mobile communication terminal 50 will lock an electronic payment function first (step Sa1). Specifically, the control unit 51 prevents the information from being exchanged between the IC chip unit 56 and the reading terminal 40 by cutting off the power supply to the IC chip unit 56.

  When the electronic settlement function is locked, the control unit 51 acquires a motion signal supplied by the motion detection unit 57 and detects a change in the position of the own device (step Sa2). Subsequently, the control unit 51 compares the position variation with the pattern information stored as the pattern data file (step Sa3), and whether or not the detected position variation corresponds to the pattern represented by the pattern information. Is determined (step Sa4). Here, when the detected position variation is included in the range of the pattern represented by any of the plurality of pattern information, the control unit 51 determines that the position variation corresponds to the pattern represented by the pattern information.

  When the detected position change corresponds to the pattern represented by the pattern information (step Sa4: YES), the control unit 51 unlocks the electronic payment function (step Sa5). That is, the control unit 51 supplies power to the IC chip unit 56 so that the IC chip unit 56 can respond when an inquiry is received from the reading terminal 40. On the other hand, if the detected position variation does not correspond to the pattern represented by any pattern information (step Sa4: NO), the control unit 51 continues to detect the position variation of the own device (step Sa2), and the subsequent processing repeat.

  Subsequently, the control unit 51 monitors communication in the IC chip unit 56 while making the electronic payment function available. That is, the control unit 51 determines whether or not the information stored in the IC chip unit 56 has been read / written (step Sa6). This determination is repeated until reading / writing by the IC chip unit 56 is recognized or until a predetermined period (for example, 5 seconds) elapses. That is, when the controller 51 cannot recognize reading / writing information stored in the IC chip 56 (step Sa6: NO), the controller 51 determines whether or not a predetermined time has elapsed since the lock was released (step Sa7). ), If not yet passed, the process of step Sa6 is performed again.

  When reading / writing is performed on the information stored in the IC chip unit 56 (step Sa6: YES), the control unit 51 considers that the reading terminal 40 has accessed the information stored in the IC chip unit 56, and the electronic The settlement function is locked again (step Sa8). On the other hand, when reading / writing by the IC chip unit 56 is not recognized even after a predetermined time has passed since the lock was released (step Sa7: YES), the control unit 51 considers that there was no access by the reading terminal 40 at this time, The electronic settlement function is locked again (step Sa8).

  When the electronic settlement function is locked, the control unit 51 stores the detected position variation as a history (step Sa9). That is, the control unit 51 updates the history data file by adding a new record. At this time, the control unit 51 also stores whether or not the IC chip unit 56 has performed reading and writing.

  Thereafter, the control unit 51 performs a process of rewriting the pattern data file in order to suppress unnecessary unlocking. This process can be divided into a deletion process (step Sa11) and a correction process (step Sa12). These processes are executed when the number of records in the history data file reaches a predetermined number or when it is time to perform these processes. That is, the control unit 51 determines whether or not the number of records in the history data file has reached a predetermined number or when it is time to perform these processes (step Sa10), and when any of the conditions is satisfied A deletion process (step Sa11) and a correction process (step Sa12) are executed. The timing for executing the deletion process and the correction process is arbitrary. For example, it may be set when a predetermined time (for example, one hour) has elapsed since the deletion process and the correction process were executed previously.

  Here, the contents of the deletion process will be described. FIG. 9 is a flowchart showing the contents of the deletion process. Explaining along the figure, first, the control unit 51 determines whether or not the position data corresponding to the pattern represented by the pattern information is stored in the history data file for any of the pattern information stored as the pattern data file. Is determined (step Sa111). When the position variation corresponding to the pattern represented by the pattern information to be processed is not stored in the history data file (step Sa111: NO), the control unit 51 deletes the pattern information from the pattern data file (step Sa112). .

  In contrast, if the position variation corresponding to the pattern represented by the pattern information to be processed is stored in the history data file (step Sa111: YES), the control unit 51 stores the position variation in the history data file. When the data is read or written by the IC chip unit 56, it is determined (step Sa113). When reading / writing is performed by the IC chip unit 56 (step Sa113: YES), the control unit 51 performs the next process without deleting the pattern information to be processed (step Sa114). On the other hand, if the history is stored but the IC chip unit 56 does not read or write (step Sa113: NO), the control unit 51 performs processing according to the number of histories corresponding to the pattern information to be processed. I do.

  The control unit 51 determines the number of histories corresponding to the pattern information to be processed (step Sa115). If the number of histories corresponding to the pattern information to be processed is n or more (step Sa115: YES), the control unit 51 deletes the pattern information (step Sa116). On the other hand, when the number of histories corresponding to the pattern information to be processed is less than n (step Sa115: NO), the control unit 51 performs the next process without deleting the pattern information to be processed ( Step Sa117). Note that the value of n at this time is arbitrary, and may be determined appropriately.

  After determining whether or not the pattern information to be processed can be deleted in this way, the control unit 51 determines whether or not the above-described processing has been executed for all the pattern information stored as the pattern data file (step Sa118). ). If there is unprocessed pattern information (step Sa118: NO), the processing after step Sa111 is executed with the pattern information as a processing target. On the other hand, when the above-described processing is executed for all pattern information (step (Sa118: YES), the deletion process is terminated.

  Next, the content of the correction process will be described. FIG. 10 is a flowchart showing the content of the correction process. Explaining along the figure, first, the control unit 51 recognizes any pattern information stored as a pattern data file, corresponding to the pattern represented by the pattern information, and read / write by the IC chip unit 56. All the positional fluctuations at that time are extracted from the history data file (step Sa121). Then, the control unit 51 compares all the extracted position fluctuations with the pattern represented by the pattern information to be processed, and corrects the deviation information of the pattern information (step Sa122).

  FIG. 11 is a diagram for explaining the processing in step Sa122. As shown in FIG. 11A, for example, pattern information including position variation information indicated by a curve A and deviation information indicated by upper and lower broken lines D1 and D2 is assumed. Then, it corresponds to the pattern represented by the pattern information, and three kinds of position fluctuations indicated by the curves a and b are stored as history as position fluctuations when reading / writing by the IC chip unit 56 is recognized. To do. In this case, the control unit 51 differs from any of the curves a and b in the range included as the deviation information, that is, the range inside the broken lines D1 and D2 shown in FIG. A process of excluding a range different from a predetermined level from the deviation information is performed. The deviation information after this processing is performed is as indicated by broken lines D3 and D4 in FIG. This means that the degree of deviation (deviation) represented by the deviation information is reduced. By doing in this way, the pattern represented by the pattern information can be made closer to the user's operation, and it is possible to prevent the lock from being unnecessarily released.

  Returning to the description of FIG. The control unit 51, for any of the pattern information stored as a pattern data file, corresponds to the pattern represented by the pattern information, and records all positional fluctuations when reading / writing by the IC chip unit 56 is not recognized. Extract from the data file (step Sa123). Then, the control unit 51 compares all the extracted position fluctuations with the pattern represented by the pattern information to be processed, and corrects the deviation information of the pattern information (step Sa124).

  FIG. 12 is a diagram for explaining the processing of step Sa124. As shown in FIG. 12A, for example, pattern information including position variation information indicated by a curve A and deviation information indicated by upper and lower broken lines D1 and D2 is assumed. It is assumed that the position fluctuation indicated by the curve c is stored as a history corresponding to the pattern represented by the pattern information and as the position fluctuation when reading / writing by the IC chip unit 56 is not recognized. In this case, the control unit 51 is outside the curve c (that is, the side having a large deviation from the curve A) in the range included as the deviation information, that is, the range inside the broken lines D1 and D2 shown in FIG. Is excluded from the deviation information. Deviation information after this processing is performed is shown by broken lines D3 and D4 shown in FIG. This means that the degree of deviation (deviation) represented by the deviation information is reduced as in the process of step Sa122. Therefore, by doing in this way, it becomes possible to suppress that a lock | rock is cancelled | released unnecessarily.

  Returning to the description of FIG. After correcting the deviation information for certain pattern information, the control unit 51 determines whether or not the above-described processing has been executed for all of the pattern information stored as the pattern data file (step Sa125). If there is unprocessed pattern information (step Sa125: NO), the processing after step Sa121 is executed with the pattern information as a processing target, while the above-described processing is executed for all pattern information (step (Sa125: YES), the deletion process is terminated.

  The deletion process and the correction process shown in FIG. 8 are as described above. After these processes, the control unit 51 performs the processes after step Sa2 except when an event to terminate the management application (for example, an instruction to stop the management application by the user or termination of the OS 511) occurs. repeat. That is, the control unit 51 determines whether or not an event for terminating the management application has occurred (step Sa13). When such an event occurs (step Sa13: YES), the management application is terminated.

  By performing the above processing, the mobile communication terminal 50 according to the present embodiment can unlock the electronic payment function only for a predetermined period after the position variation of the specific pattern occurs. The position fluctuation when the lock is released is a position fluctuation peculiar when the user holds the mobile communication terminal 50 over the reading terminal 40. Therefore, according to the mobile communication terminal 50, the electronic payment function can be unlocked only when necessary, without the user performing a special operation. Further, since the locked state is maintained except when the position of the specific pattern is changed, for example, it is possible to prevent the payment information from being stolen without the user's knowledge by a small portable reader. It is also possible.

  Further, according to the mobile communication terminal 50 of the present embodiment, the position variation corresponding to the pattern information is stored as a history, and the lock process is unnecessarily released by executing the above-described deletion process and correction process. Can be suppressed. Therefore, the mobile communication terminal 50 learns the movement when the user holds the mobile communication terminal 50 by repeating the use of the mobile communication terminal 50, and is a natural operation only when the user needs it. The lock can be released.

[Second Embodiment]
Subsequently, a second embodiment of the present invention will be described. The configuration of the present embodiment is the same as that of the first embodiment described above, although there is a difference in the functions realized by the management application. Therefore, the description of the payment system according to the present embodiment uses the same reference numerals as the payment system 100 of the first embodiment.

  In the present embodiment, the mobile communication terminal 50 has a function of receiving an input of position variation from a user and registering it as pattern information. In other words, the user can release the lock using the position variation of an appropriate pattern determined by the user by this function. In this case, the operation of the user holding the mobile communication terminal 50 over the reading terminal 40 may be an operation of shaking (shaking) the mobile communication terminal 50 several times during the holding.

  The process of registering pattern information is not executed simultaneously with the process of unlocking the electronic payment function shown in FIG. That is, the mobile communication terminal 50 has a mode for executing a process for registering pattern information and a mode for executing a process for releasing the lock of the electronic payment function, and operates in any of these modes. The mode is switched by the user pressing a predetermined button (hereinafter referred to as “mode switching button”) on the operation unit 53. In the following, the mode for executing the processing for unlocking the electronic payment function is referred to as “normal mode”, and the mode for executing the processing for registering pattern information is referred to as “registration mode”.

  In addition to the pattern data file and the history data file, the prohibited pattern data file is stored in the storage area allocated for the management application. In the prohibited pattern data file, information representing a pattern that should be prohibited by the user is described in the same format as the pattern information described above. Described in the prohibited pattern data file are, for example, patterns corresponding to position fluctuations that occur when the user walks and vibrations during traveling of a train or the like.

  FIG. 13 is a flowchart showing processing executed by the control unit 51 of the mobile communication terminal 50 when the user registers pattern information. Explaining along the figure, first, the control unit 51 determines whether or not an operation signal corresponding to the mode switching button is supplied from the operation unit 53 (step Sb1). When receiving the operation signal corresponding to the mode switching button (step Sb1: YES), the control unit 51 executes the process corresponding to the registration mode, while not receiving the operation signal corresponding to the mode switching button (step Sb1). : NO), the process corresponding to the normal mode is executed (step Sb7). Since the process corresponding to the normal mode is the same as the process described with reference to FIG. 8 in the first embodiment, the description thereof is omitted here.

  In the registration mode, the control unit 51 acquires the motion signal supplied by the motion detection unit 57 and detects the position fluctuation of the own device (step Sb2). When the position variation of the own device is detected, the control unit 51 refers to the prohibited pattern data file, so that whether or not the detected position variation corresponds to the pattern represented by the information stored in the prohibited pattern data file. Is determined (step Sb3).

  When the detected position variation corresponds to a pattern represented by information stored in the prohibition pattern data file, that is, when the detected position variation corresponds to a pattern whose registration should be prohibited (step Sb3: YES), the control unit 51 notifies that registration of the detected position variation as pattern information is prohibited (step Sb4). Specifically, for example, the lamp 55a of the information notification unit 55 is turned on, or the vibrator 55b is vibrated with a predetermined vibration pattern.

  On the other hand, when the detected position variation does not correspond to a pattern that should be prohibited from being registered (step Sb3: NO), the control unit 51 stores the detected position variation as pattern information in the pattern data file (step Sb5). The control unit 51 generates position variation information and deviation information based on the detected position variation, and stores this as pattern information. And the control part 51 notifies that the detected position variation was registered as pattern information (step Sb6). In this case, the control unit 51 performs notification in a mode different from the above-described step Sb4 by changing the vibration pattern of the vibrator 55b.

  When the user is notified of either step Sb4 or Sb5, the control unit 51 ends the operation in the registration mode and switches to the operation in the normal mode. That is, the control unit 51 executes processing corresponding to the normal mode (step Sb7).

  By performing the above processing, the mobile communication terminal 50 of the present embodiment unlocks the electronic payment function by performing a predetermined operation designated by the user, and common position fluctuations that frequently occur are pattern information. It is possible to prevent registration as. Therefore, according to the mobile communication terminal 50, it is possible to prevent the electronic payment function from being unlocked at a timing not intended by the user.

Note that the configuration of the present embodiment also has a common part with the configuration of the payment system 100 of the first embodiment described above. For this reason, such portions are denoted by the same reference numerals as those in the first embodiment described above, and description thereof will be omitted as appropriate.

As shown in the figure, the payment system 200 includes the Internet 10, a mobile packet communication network 20, a payment server 60, a reading terminal 70, and a mobile communication terminal 80.

  FIG. 15 is a block diagram showing the configuration of the settlement server 60.

The storage unit 62 is a storage device such as an HDD (Hard Disk Drive) and stores various data. The communication unit 63 is an interface device for performing communication via the Internet 10.

  The storage unit 62 stores a plurality of data representing movement (position variation) of the mobile communication terminal 80. This data is data that is transmitted to the reading terminal 70 and displayed on the display unit 73, and is data for instructing the user of the mobile communication terminal 80 to move the mobile communication terminal 80. This data is hereinafter referred to as “instruction data”.

  Next, FIG. 16 is a block diagram illustrating a configuration of the reading terminal 70. As shown in the figure, the reading terminal 70 includes a control unit 71, a communication unit 72, a display unit 73, a non-contact communication unit 74, an infrared communication unit 75, and a motion detection unit 76. The configurations of the control unit 71, the communication unit 72, the display unit 73, and the non-contact communication unit 74 are almost the same as the configurations of the control unit 41, the communication unit 42, the display unit 43, and the non-contact communication unit 44 of the reading terminal 40, respectively. It is the same. The infrared communication unit 71 communicates with the mobile communication terminal 80 using infrared rays. The motion detection unit 76 includes an acceleration sensor 76 a and a gyro sensor 76 b having the same configuration as the motion detection unit 87 of the mobile communication terminal 80, and detects the movement of the reading terminal 70.

  Next, FIG. 17 is a block diagram showing a configuration of the mobile communication terminal 80. As shown in the figure, the mobile communication terminal 80 includes a control unit 81, a radio communication unit 82, an operation unit 83, a display unit 84, an information notification unit 85, an IC chip unit 86, and a motion detection unit 87. And an infrared communication unit 88. The configurations of the control unit 81, the wireless communication unit 82, the operation unit 83, the display unit 84, the information notification unit 85, the IC chip unit 86, and the motion detection unit 87 are the same as those of the control unit 51 of the mobile communication terminal 50 and the wireless communication, respectively. The configuration of the unit 52, the operation unit 53, the display unit 54, the information notification unit 55, the IC chip unit 56 and the motion detection unit 57 is almost the same. The infrared communication unit 88 communicates with the reading terminal 70 using infrared rays.

  The configuration of the payment system 200 is as described above. Next, the operation in the payment system 200 will be described. FIG. 18 is a sequence chart showing operations of the payment server 60, the reading terminal 70 and the mobile communication terminal 80 in the payment system 200. Explaining along the figure, first, the control unit 61 of the settlement server 60 reads any of the instruction data stored in the storage unit 62 and transmits it to the reading terminal 70 via the communication unit 63 (step). Sc1). Then, when receiving the instruction data, the control unit 71 of the reading terminal 70 displays the movement of the mobile communication terminal 80 indicated by the instruction data on the display unit 73 (step Sc2).

  FIG. 19 is a diagram illustrating an example of a screen displayed on the display unit 73 of the reading terminal 70 at this time. As shown in the figure, a predetermined image representing the movement of the mobile communication terminal 80 is displayed on the display unit 73. In the example shown in the figure, the user of the mobile communication terminal 80 instructs the mobile communication terminal 80 that moves over the reading terminal 70 to move in a circle.

  Returning to the description of FIG. When the reading terminal 70 performs display corresponding to the instruction data, the control unit 81 of the mobile communication terminal 80 unlocks the electronic payment function in accordance with a user operation (step Sc3). That is, the user unlocks the electronic payment function before holding the mobile communication terminal 80 over the reading terminal 70. In the present embodiment, the method for unlocking the electronic payment function is not particularly limited. That is, a release method different from the first and second embodiments described above may be used.

  Thereafter, the mobile communication terminal 80 becomes communicable with the reading terminal 70 when the user holds the mobile communication terminal 80 over the reading terminal 70. If it will be in such a state, IC chip part 86 of mobile communication terminal 80 will transmit settlement information to reading terminal 70 (Step Sc4). Further, when the control unit 81 of the mobile communication terminal 80 detects that the IC chip unit 86 has transmitted the settlement information, it transmits a motion signal to the reading terminal 70 (step Sc5).

  When the settlement information and the motion signal are received, the control unit 71 of the reading terminal 70 corrects the received motion signal based on the motion signal detected by the motion detection unit 72 of the own device (step Sc6). Specifically, if there is a common component between the received motion signal and the motion signal detected by the motion detection unit 72, the control unit 71 removes this. The motion signal corrected in this way is hereinafter referred to as a “corrected motion signal”. After correcting the motion signal, the control unit 71 of the reading terminal 70 transmits the payment information and the corrected motion signal to the payment server 60 via the communication unit 72 (step Sc7). At this time, the control unit 71 may add information about the own device to the payment information.

  When the payment information and the corrected motion signal are received, the control unit 61 of the payment server 60 determines whether or not the corrected motion signal corresponds to the position variation represented by the instruction data transmitted by the own device (step Sc8). At this time, the corrected motion signal and the position variation represented by the instruction data do not need to completely coincide with each other, and may include a certain amount of deviation.

  When the corrected motion signal corresponds to the position variation represented by the instruction data transmitted by the own device (step Sc8: YES), the control unit 61 regards the payment information received simultaneously with the corrected motion signal as valid, Settlement information is stored in the storage unit 62 (step Sc9). On the other hand, when the corrected motion signal does not correspond to the position variation represented by the instruction data transmitted by the own device (step Sc8: NO), the control unit 61 regards the settlement information received simultaneously with the corrected motion signal as invalid. The settlement information is deleted without being stored in the storage unit 62 (step Sc10).

  By performing the above processing, the settlement server 60 of the present embodiment can determine whether or not the received settlement information is from a valid user. Thereby, for example, even when there are a plurality of mobile communication terminals 80 in a range where the reading terminal 70 can communicate, the intended user's payment information is validated and other unintended user's settlement information is invalidated. It becomes possible to do.

  Further, according to the reading terminal 70 of the present embodiment, it is possible to correct the motion signal received from the mobile communication terminal 80 based on the motion signal acquired in the own device. Thereby, for example, even when the electronic payment function is used in a moving train, it is possible to prevent erroneous recognition.
