  In the invention of claim 11, the predetermined request includes display control information related to a screen display control method for changing the display time of the information code by the display means.

  Thus, if the decoding of the information code by the information code reading device fails if the display time of the information code by the display means of the portable terminal is not appropriate, the information code is displayed with a display time suitable for reading by the information code reading device. By displaying the display control information to the portable terminal so that is displayed, it is possible to automatically adjust the information code so that it is displayed at a display time suitable for decoding. For example, when the failure in decoding the information code is caused by the display of the information code being terminated by the control based on the power saving mode or the like before the information code is imaged by the imaging means, the user When attempting to read the information code again, the information code display time can be lengthened to facilitate successful reading of the information code.

  In the twelfth aspect of the invention, when the predetermined information is acquired by decoding by the decoding means, the information processing means restores the information code screen display control method by the display means changed by the display control information to the original control method. A return instruction for sending is sent via the apparatus-side communication means. Further, when the display control means receives the return instruction via the terminal side communication means, the control method of the screen display of the information code by the display means changed based on the second display control information is returned to the original control method. The

  Thereby, after temporarily changing the control method of the screen display of the information code in a portable terminal based on display control information, it can return to the state before a change automatically. Therefore, users need to be aware that the control method of the information code screen display is changed as well as the control method of the information code screen display need not be restored.

It is configured. The communication unit 36 may correspond to an example of “terminal side communication unit”.

  Next, the terminal-side payment process executed by the control unit 31 of the portable terminal 30 and the device-side payment process executed by the control unit 21 of the payment apparatus 20 at the time of payment using the information code C will be described. Will be described in detail. In the present embodiment, the information code C in which the monetary information is recorded is configured as a QR code (registered trademark). However, the present invention is not limited to this, and information codes of other code types such as a data matrix code, maxi It may be configured as a code or the like.

First, device-side payment processing executed by the control unit 21 of the payment device 20 will be described in detail with reference to the flowchart shown in FIG.
When a user possessing the portable terminal 30 purchases a predetermined amount of goods using the information code C, a predetermined instruction is input from the POS register 11 to the settlement apparatus 20 via the communication unit 27. The control unit 21 starts the apparatus-side payment process. First, the payment condition acquisition process shown in step S 101 shown in FIG. 4 is performed, and the payment amount information (information for payment) of the purchased product transmitted from the POS register 11 is acquired (received) via the communication unit 27. Then, the information code or the like held over the reading port 29 can be captured by the imaging unit 22. In addition, the light emitting unit 24 enters a predetermined light emitting state, and the imaging unit 22 is notified that preparation for imaging the information code C is completed, and guidance for making it easy to hold the information code C over the reading port 29. Is made.

  Next, the portable terminal detection process shown in step S103 is performed, and a process (for example, a known polling process) for detecting the portable terminal 30 capable of short-range wireless communication using the NFC function by the communication unit 27 is performed. . Then, in the determination process shown in step S105, it is determined whether or not the mobile terminal 30 has been detected. Here, if the portable terminal 30 cannot be detected because the portable terminal 30 is not held over the reading port 29 and is not within the NFC communicable range, it is determined No in step S105, and the process from step S103 above is performed. The process is repeated.

  When the portable terminal 30 is held in the NFC communicable range by holding the portable terminal 30 over the reading port 29 by the user (Yes in S105), the information code display instruction process shown in step S107 is performed. In this process, an information code display instruction for causing the portable terminal 30 to display the information code C stored in the storage unit 35 on the display unit 33 on the screen uses the NFC function by the communication unit 27 as a predetermined request. Then sent.

  Subsequently, an information code reading process shown in step S109 is performed, and a process for decoding the information code imaged by the imaging unit 22 via the reading port 29 is performed. Then, in the determination process shown in step S111, it is determined whether the captured information code has been successfully decoded (decoded), and the determination of No is repeated until the decoding in step S109 is successful.

  Then, as will be described later, the information code C is displayed on the screen of the display unit 33 of the portable terminal 30 that has received the predetermined request, so that the information code is transmitted through the reading port 29 by the imaging unit 22 in step S109. If C is imaged and the information code C is successfully decoded (decoded), it is determined Yes in step S111. In step S109, the imaging unit 22 may correspond to an example of “imaging unit”, and the control unit 21 may correspond to an example of “decoding unit”.

  Subsequently, in the payment process shown in step S113, a process related to payment is performed based on information (predetermined information) related to the payment process acquired by decoding the information code C. Specifically, for example, when the prepaid balance amount of the A settlement company is acquired by decoding the information code C, processing is performed to reduce the prepaid balance amount according to the payment amount information. Note that the control unit 21 that executes the process of step S113 may correspond to an example of an “information processing unit”.

  When the payment using the information code C is completed as described above, the information code erasure instruction process shown in step S115 is performed. In this process, an information code erasure instruction for erasing the information code C from the display screen of the display unit 33 is transmitted to the mobile terminal 30 using the NFC function of the communication unit 27. Thereafter, the apparatus-side payment process ends.

Next, the terminal-side payment process executed by the control unit 31 of the mobile terminal 30 will be described in detail using the flowchart shown in FIG.
When the terminal-side payment process is started by the control unit 31, first, the communication preparation process shown in step S201 of FIG. 5 is performed, and the NFC function can be used to communicate with the payment apparatus 20 via the communication unit 36. It becomes. Subsequently, in the determination process shown in step S203, the determination of No is repeated until the information code display instruction is received from the settlement apparatus 20 as a predetermined request.

  During such repeated determination, the mobile terminal 30 is brought close to the payment apparatus 20 so that the user holds the display unit 33 against the reading port 29 so that NFC communication is possible via the communication unit 36. When the information code display instruction is received as a predetermined request from the settlement apparatus 20 that has become, the imaging unit 22 of the settlement apparatus 20 displays the display screen of the display unit 33 based on the communication state by the communication unit 36 that is capable of NFC communication. A state where imaging is possible is estimated, and it is determined Yes in step S203.

  Subsequently, an information code display process shown in step S205 is performed, and the information code C stored in the storage unit 35 is displayed on the screen of the display unit 33. That is, as illustrated in FIG. 6A, the display unit 33 on which the information code C is not displayed on the screen is brought close to the reading port 29 of the settlement apparatus 20 so that the user can access the operation unit 34. In response to the information code display instruction received from the settlement apparatus 20 without performing an operation for displaying the information code C on the screen, the information code C is automatically displayed on the display unit as illustrated in FIG. 33 is displayed on the screen.

  When the information code C is automatically displayed on the screen in this way, it is determined as No in the determination process shown in step S207 if the information code erasure instruction is not received from the settlement apparatus 20. After the determination of No in step S207, it is determined Yes in the determination process shown in step S209 if communication with the settlement apparatus 20 is possible using NFC communication, and the process from step S205 is performed. Made. That is, the state in which the information code C is displayed on the display unit 33 is continued until the information code erasing instruction is received from the payment device 20 or communication with the payment device 20 using NFC communication is disabled. .

  Then, in a state where the information code C is displayed on the display unit 33, the information code deletion instruction is received from the payment apparatus 20 (Yes in S207), or the portable terminal 30 is released from the payment apparatus 20. When communication using the NFC communication with the settlement apparatus 20 is disabled (No in S209), the information code erasure process shown in step S211 is performed. As a result, the information code C is erased from the display screen of the display unit 33, and the terminal-side payment process ends.

  As described above, in the payment system 10 according to the present embodiment, the mobile terminal 30 receives the information code display instruction (predetermined request) from the payment device 20 via the communication unit 36 by using the NFC function. Then, the information code C is displayed on the screen of the display unit 33 under the control of the control unit 31. Further, in the payment apparatus 20, when the information code display instruction is transmitted by the communication unit 27 by using the NFC function, and the information code C imaged by the imaging unit 22 is decoded, the information code C obtained by this decoding is obtained. Payment processing based on information is performed.

  Thereby, in the mobile terminal 30 that has received the information code display instruction (predetermined request) from the settlement apparatus 20, the information code C is automatically displayed on the display unit 33 without the user operating the mobile terminal 30. Is done. For this reason, the user only has to hold the mobile terminal 30 over the settlement apparatus 20 and cause the imaging unit 22 to image the information code C displayed on the screen. Therefore, it is possible to reduce the trouble of operating the mobile terminal 30 when the payment apparatus 20 reads the information code C displayed on the screen of the mobile terminal 30.

  In particular, after an information code display instruction is received from the settlement apparatus 20 via the communication unit 36, the display unit 33 is displayed by the imaging unit 22 of the settlement apparatus 20 based on the communication state of the communication unit 36 capable of NFC communication. When it is estimated that the display screen can be imaged (Yes in S203), the information code C is displayed on the display unit 33 by the information code display process.

  Thereby, when it is not estimated that the imaging unit 22 can capture the display screen of the display unit 33, that is, when it is estimated that the mobile terminal 30 is away from the settlement apparatus 20, the information code C is displayed. The screen is not displayed on the section 33. For this reason, it is possible to prevent unnecessary display of the information code C in which information related to money information or the like for which security is required is displayed on the screen, and to reduce the trouble of operating the mobile terminal 30 while reducing the security related to the information code C. Can be improved.

  Further, in the payment apparatus 20, when the information code C is decoded by the information code reading process (S109) and information (predetermined information) related to the payment process is acquired, the information code C is deleted from the display screen of the display unit 33. An information code erasing instruction is transmitted through the communication unit 27 (S115). Then, in the portable terminal 30, when the information code deletion instruction is received via the communication unit 36 (Yes in S207), the information code C is deleted from the display screen of the display unit 33 by the information code deletion process (S211). .

  As described above, when the payment apparatus 20 acquires information related to the payment process from the mobile terminal 30, there is no need to display the information code C on the screen. The screen of information code C is erased. Thereby, it is possible to prevent the information code C from being displayed on the screen unnecessarily, and it is possible to improve the security related to the information code C while reducing the trouble of operating the mobile terminal 30.

  Furthermore, when the information code C is being displayed on the display unit 33 and the communication device 36 cannot communicate with the payment apparatus 20 (No in S209), the information code erasing process (S211) causes the display unit 33 to perform communication. The information code C is erased from the display screen.

  As described above, when the information code C is displayed on the display unit 33 and cannot communicate with the payment apparatus 20, the mobile terminal 30 held over the payment apparatus 20 is separated from the payment apparatus 20. Presumed. In such a case, there is no need to display the information code C on the screen, so the screen of the information code C is positively deleted. Thereby, it is possible to prevent the information code C from being displayed on the screen unnecessarily, and it is possible to improve the security related to the information code C while reducing the trouble of operating the mobile terminal 30.

  As a modification of the present embodiment, a plurality of types of information codes that can be used in the payment apparatus 20 may be prepared and stored on the display unit 33 so as to be screen-displayable in the storage unit 35 of the mobile terminal 30. . Here, the plurality of types of information codes include, for example, an agreement with a plurality of settlement companies in advance such as an information code for performing settlement using the A settlement company and an information code for performing settlement using the B settlement company. It is assumed that the information code becomes available.

  In this case, in step S107 in the apparatus-side payment process of the payment apparatus 20, an information code display instruction (in order to select an information code corresponding to the payment to be preferentially used in the store from among the plurality of types of information codes ( A predetermined request) can be set and transmitted. That is, the information code display instruction (predetermined request) is set so that one of a plurality of information codes can be selected. In addition, the operator of the payment apparatus 20 confirming the desired payment type from the user inputs the payment type and the like, so that an information code corresponding to the input is selected from the plurality of types of information codes. An information code display instruction can be set in and transmitted. In step S205 in the terminal-side payment process of the portable terminal 30, one information code selected in accordance with the received information code display instruction among the plurality of types of information codes is displayed on the screen of the display unit 33.

  As a result, the settlement apparatus 20 can read a desired information code from among a plurality of information codes in response to an information code display instruction (predetermined request) transmitted to the mobile terminal 30. Since the payment apparatus 20 does not request an operation for displaying an information code to be read on the screen, the convenience of the payment system 10 can be improved while reducing the trouble of operating the mobile terminal 30.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
In the second embodiment, the predetermined request transmitted from the settlement apparatus 20 to the mobile terminal 30 includes display control information related to a method for controlling the screen display of the information code by the display unit 33. The mobile terminal 30 performs the display control. It differs from the first embodiment in that an information code is displayed on the screen of the display unit 33 using a control method based on information. Note that the settlement apparatus 20 and the mobile terminal 30 according to the second embodiment have the same hardware configuration as the settlement apparatus 20 and the mobile terminal 30 according to the first embodiment, and are denoted by the same reference numerals and have a hardware configuration. Detailed description is omitted.

First, the apparatus-side payment process executed by the control unit 21 of the payment apparatus 20 will be described in detail using the flowchart shown in FIG.
First, the settlement condition acquisition process shown in step S101 shown in FIG. 7 is performed in the same manner as in the first embodiment. Further, the subsequent processes in steps S103 and S105 are the same as those in the first embodiment, and thus detailed description thereof is omitted. If the mobile terminal 30 cannot be detected in the determination process shown in step S105, it is determined No in step S105, and the mobile terminal re-detection process shown in step S301 is performed. In step S301, after a predetermined time (for example, 5 seconds) has elapsed from the determination process shown in step S105, a process for detecting the portable terminal 30 capable of short-range wireless communication using the NFC function by the communication unit 27 ( For example, a known polling process) is performed.

  And it is determined by the determination process shown to step S303 whether the portable terminal 30 was detected by the method similar to step S105. Here, if the portable terminal 30 cannot be detected because the portable terminal 30 is not held over the reading port 29 and is not within the NFC communicable range, it is determined No in step S303, and the information shown in step S305 A code reading process is performed, and a process for decoding the information code imaged by the imaging unit 22 through the reading port 29 is performed. For example, in a portable terminal that does not have a function of performing short-range wireless communication using the NFC function, it is determined No in steps S105 and S303 without receiving an instruction to display an information code transmitted from the settlement apparatus 20 When the user performs an operation on the portable terminal, the information code displayed on the screen is read. Thereafter, the apparatus-side payment process ends.

  On the other hand, when the mobile terminal 30 in the NFC communicable range is detected by holding the mobile terminal 30 over the reading port 29 by the user (Yes in S105), the display method and information code display instruction shown in step S307 are detected. Processing is done. In this process, in order to cause the display unit 33 to display on the display unit 33 the display control information related to the control method of the screen display of the information code C by the display unit 33 and the information code C stored in the storage unit 35. The information code display instruction is transmitted as a predetermined request using the NFC function of the communication unit 27. For example, in the display control information, as a method of controlling the screen display of the information code C by the display unit 33, the light amount of the backlight is medium, the display enlargement / reduction ratio of the information code C is 100%, the screen off time (in the power saving setting). When auto-off control is performed, information for instructing the setting so that the time from when the information code C is displayed until it is erased is set to 15 seconds is included. The information code display instruction is information for causing the mobile terminal 30 to display the information code C stored in the storage unit 35 on the display unit 33 on the screen.

  Subsequently, the information code reading process shown in step S109 is performed in the same manner as in the first embodiment, and the process for decoding the information code imaged by the imaging unit 22 through the reading port 29 is performed. Then, in the determination process shown in step S111 performed in the same manner as in the first embodiment, it is determined whether or not the captured information code has been successfully decoded (decoded).

  If it is determined in step S111 that the decoding of the information code C has failed (No in S111), failure cause identification processing shown in step S309 is performed. In this process, the cause of failure in decoding the information code C in the information code reading process shown in step S109 is specified. For example, if the size of the imaged information code C is appropriate for decoding, and the decoding fails because the light and darkness of the cells of the information code C cannot be determined, it is determined that the contrast of the imaged information code C is small. Identify the cause. In addition, when the size of the captured information code C is not suitable for decoding, and the decoding fails because the light and darkness of the cell of the information code C cannot be determined, the size of the captured information code C is small. Identify too much as the cause of failure. Further, when the captured image includes only a part of the information code C, the fact that the captured information code C is too large is specified as a cause of failure. Further, when the information code C is not included in the captured image, the lack of exposure time of the display unit 33 of the mobile terminal 30 is specified as the cause of failure.

  Subsequently, a display method instruction process shown in step S311 is performed. In this process, display control information for successful decoding is generated based on the specified cause of decoding failure, and a predetermined request including this display control information is transmitted to the portable terminal 30. For example, when the cause of the failure is that the contrast of the captured information code C is small, the screen display control is performed so that the contrast of the information code C displayed by the display unit 33 is larger than that captured in S109. A predetermined request including display control information regarding the method is transmitted. Further, when the cause of the failure is that the size of the captured information code C is too small, the screen display is such that the size of the information code C displayed by the display unit 33 is larger than when captured in S109. A predetermined request including display control information regarding the control method is transmitted. Further, when the cause of the failure is that the size of the captured information code C is too large, the screen display is such that the size of the information code C displayed by the display unit 33 is smaller than when captured in S109. A predetermined request including display control information regarding the control method is transmitted. Further, when the cause of the failure is an insufficient exposure time of the display unit 33, a screen display control method (auto-off) in which the display time of the information code C by the display unit 33 is longer than that in S109. A predetermined request including display control information regarding how to extend the time or cancel the power saving mode is transmitted. Then, the process from step S109 is repeated until it is determined that the decoding is successful in the process of step S111. The control unit 21 that executes the process of step S311 may correspond to an example of a “generation unit” and an “information processing unit”.

  When the information code C is imaged by the imaging unit 22 through the reading port 29 in step S109 and decoding (decoding) of the information code C is successful, it is determined Yes in step S111. Subsequently, in the payment process shown in step S113 performed in the same manner as in the first embodiment, a process related to payment is performed based on information (predetermined information) related to the payment process acquired by decoding the information code C.

  When the payment using the information code C is completed as described above, the information code erasure and display method return instruction processing shown in step S313 is performed. In this process, the information code erasure instruction for erasing the information code C from the display screen of the display unit 33 and the information code C by the display unit 33 changed by the instruction process of S307 or S311 are given to the portable terminal 30. A return instruction for returning the screen display control method to the original control method (for example, the control method before being changed by the instruction processing in S307) is transmitted using the NFC function of the communication unit 27. Thereafter, the apparatus-side payment process ends. The control unit 21 that executes the process of step S313 may correspond to an example of “information processing unit”.

Next, the terminal-side payment process executed by the control unit 31 of the portable terminal 30 will be described in detail using the flowchart shown in FIG.
When the terminal-side payment process is started by the control unit 31, first, the communication preparation process shown in step S201 of FIG. 8 is performed, and the NFC function can be used to communicate with the payment apparatus 20 via the communication unit 36. It becomes. Subsequently, in the determination process shown in step S401, the determination of No is repeated until the display method and the information code display instruction are received from the settlement apparatus 20 as a predetermined request.

  During such repeated determination, the mobile terminal 30 is brought close to the payment apparatus 20 so that the user holds the display unit 33 against the reading port 29 so that NFC communication is possible via the communication unit 36. When the display control information and the information code display instruction (the instruction transmitted in S307) are received as a predetermined request from the settlement apparatus 20 that has become the settlement apparatus 20, the settlement apparatus 20 is based on the communication state of the communication unit 36 capable of NFC communication. The state in which the display screen of the display unit 33 can be imaged by the imaging unit 22 is estimated, and it is determined Yes in step S401.

  Subsequently, an information code display process shown in step S403 is performed, and the information code C stored in the storage unit 35 is displayed on the display unit 33 using the control method based on the received display control information. The That is, as illustrated in FIG. 6A, the display unit 33 on which the information code C is not displayed on the screen is brought close to the reading port 29 of the settlement apparatus 20 so that the user can access the operation unit 34. In response to the information code display instruction received from the settlement apparatus 20 without performing an operation for displaying the information code C on the screen, the information code C is automatically displayed on the display unit as illustrated in FIG. 33 is displayed on the screen. Further, the information code C is automatically set according to the display control information received from the settlement apparatus 20 without the user performing an operation for changing the screen display control method of the information code C on the operation unit 34. Is displayed on the display unit 33 by the display method instructed. For example, when the display control information includes information instructing setting such that the amount of light of the backlight is medium, the display enlargement / reduction ratio of the information code C is 100%, and the screen off time is 15 seconds, Under such conditions, the display unit 33 displays the information code C on the screen.

  When the information code C is automatically displayed on the screen in this way, it is determined whether or not the information code erasure and display method return instructions are received in the determination process shown in step S405. If the information code erasure and display method return instructions are not received from the settlement apparatus 20 in step S405, it is determined No. After the determination of “No” in step S405, the determination process shown in step S209 determines “Yes” if communication with the payment apparatus 20 is possible using NFC communication, and the determination process shown in S407. Then, it is determined whether or not the display control information and the information code display instruction (the instruction transmitted in S311) are received from the settlement apparatus 20 as a predetermined request. If the display control information and the information code display instruction are not received in the determination process shown in S407, it is determined No, and the process from step S403 is performed. On the other hand, if the display control information and the information code display instruction are received in the determination process shown in S407, it is determined Yes, and the display method change process shown in S409 changes to the control method based on the received display control information. Then, the processing from step S403 (processing for displaying the information code C by the display method changed in S409) is performed. That is, the information code C is displayed on the screen of the display unit 33 until an instruction to erase the information code and return to the display method is received from the payment device 20 or communication with the payment device 20 using NFC communication is disabled. The state continues. The control unit 31 that executes the process of step S409 may correspond to an example of “display control unit”.

  Here, in the display method change process shown in S409, for example, when the received display control information relates to a screen display control method for increasing the contrast of the information code C displayed by the display unit 33, the information code display process in S403 is continued. The setting is changed so as to be larger than the contrast of the information code C in the previous information code display process of S403. Further, when the received display control information relates to a screen display control method for increasing the size of the information code C displayed by the display unit 33, the information code display process in the subsequent S403 performs the information code display process in the previous S403. The setting is changed to be larger than the size of the information code C. Further, when the received display control information relates to a screen display control method for reducing the size of the information code C displayed by the display unit 33, the information code display process in the subsequent S403 performs the information code display process in the previous S403. The setting is changed so as to be smaller than the size of the information code C. Further, when the received display control information relates to a screen display control method for extending the display time of the information code C by the display unit 33, information at the time of the information code display process of the previous S403 in the subsequent information code display process of S403 The setting is changed so as to be longer than the display time of the code C (extend the auto-off time or cancel the power saving mode).

  Then, in a state where the information code C is displayed on the display unit 33, whether the instruction to erase the information code and return to the display method is received from the payment apparatus 20 (Yes in S405), or the portable terminal 30 is the payment apparatus 20 If communication with the payment device 20 using NFC communication is not possible due to being separated from (No in S209), the information code erasure and display method return processing shown in step S411 is performed. Thereby, the information code C is erased from the display screen of the display unit 33, and the control method of the screen display of the information code C by the display unit 33 changed based on the display control information received in S401 or S407 is based on the original control. Return to the method (for example, the control method before being changed by the instruction process received in S401). Thereafter, the terminal-side payment process ends. The control unit 31 that executes the process of step S411 may correspond to an example of “display control unit”.

  As described above, in the payment system 10 according to the second embodiment, the predetermined request includes the display control information related to the method for controlling the screen display of the information code C by the display unit 33. When the control unit 31 receives a predetermined request from the settlement apparatus 20 via the communication unit 36 (Yes in S401, Yes in S407), a control method based on display control information included in the predetermined request is used. The information code C is displayed on the screen of the display unit 33 (S403).

  Thereby, the control method of the screen display of the information code C on the portable terminal 30 side can be adjusted from the settlement apparatus 20 side without requiring a special operation of the portable terminal 30 by the user. In other words, by making the predetermined request transmitted from the settlement apparatus 20 include a desired control method for the screen display of the information code C, the portable terminal 30 automatically uses the desired control method for the information code C. It can be displayed on the screen. Therefore, by taking into account the environment in which the settlement apparatus 20 and the mobile terminal 30 are placed, a configuration in which a predetermined request is transmitted so that the information code C is displayed on the mobile terminal 30 by a screen display control method that is easy to read, It is possible to facilitate successful reading of the information code C by the settlement apparatus 20.

  Further, the settlement apparatus 20 includes a control unit 21 that generates display control information for successful decryption based on the cause of decryption failure when decryption of the information code C fails (No in S111). In addition, the control unit 21 transmits a predetermined request including the generated display control information via the communication unit 27 when the information code C is unsuccessful in a state where it can communicate with the settlement apparatus 20 (S311). .

  Thereby, based on the cause of failure in decoding the information code C by the settlement apparatus 20, the control method of the screen display of the information code C in the portable terminal 30 can be adjusted so that the decoding is successful. That is, the display of the information code C that can be successfully decoded based on the cause of the decoding failure can be feedback-controlled from the settlement apparatus 20 side to the mobile terminal 30 side. The information code C can be displayed. Therefore, the information code C can be easily read successfully without requiring a special operation of the mobile terminal 30 by the user based on the failure of decoding, such as holding the mobile terminal 30 over the settlement apparatus 20 again. And user convenience can be further improved. Specifically, conventionally, when reading of the information code C fails, the user can read the information by adjusting the angle or distance of the mobile terminal 30 with respect to the payment device 20 or turning the backlight on again. I had to find and read it to be successful. However, when the user tries to read the information code C again with the above configuration, such an operation becomes unnecessary, and the convenience for the user can be further improved.

  Further, the predetermined request includes display control information related to a screen display control method for changing the luminance of the display screen on which the information code C is displayed by the display unit 33.

  As a result, if the settlement of the information code C by the settlement apparatus 20 fails due to an inappropriate brightness level of the display screen in the portable terminal 30, the information code C is displayed with a contrast suitable for reading. By transmitting the display control information to the portable terminal 30, the information code C can be automatically adjusted to be displayed with a contrast suitable for decoding. For example, when the failure in decoding the information code C is due to the low contrast of the information code C displayed on the mobile terminal 30, the contrast is increased when the user tries to read the information code C again. Thus, the information code C can be easily read successfully.

  The predetermined request includes display control information related to a screen display control method for changing the size of the information code C displayed by the display unit 33.

  Accordingly, if the decryption of the information code C by the settlement apparatus 20 fails due to an inappropriate size of the information code C displayed on the display unit 33 of the mobile terminal 30, a size suitable for reading by the settlement apparatus 20 By transmitting the display control information to the portable terminal 30 so that the information code C is displayed, the information code C can be automatically adjusted to be displayed in a size suitable for decoding. . For example, when the position of the portable terminal 30 is too far from the settlement apparatus 20 and the pattern of the information code C cannot be determined, the information is increased by increasing the size without the user having to perform the operation of bringing the portable terminal 30 closer. The code C can be easily read successfully. If the position of the mobile terminal 30 is too close to the settlement apparatus 20 and only a part of the information code C is captured, the size is reduced without the user having to perform an operation of moving the mobile terminal 30 away. The information code C can be easily read successfully.

  Further, the predetermined request includes display control information related to a screen display control method for changing the display time of the information code C by the display unit 33.

  As a result, if the decryption of the information code C by the payment device 20 fails due to an inappropriate display time of the information code C by the display unit 33 of the mobile terminal 30, the display time suitable for reading by the payment device 20 is obtained. By transmitting the display control information to the portable terminal 30 so that the information code C is displayed, the information code C can be automatically adjusted to be displayed in a display time suitable for decoding. . For example, when the information code C is unsuccessfully decoded because the display of the information code C is terminated by the control based on the power saving mode or the like before the imaging unit 22 captures the information code C. When the user tries to read the information code C again, the display time of the information code C can be lengthened to facilitate the successful reading of the information code C.

  When the predetermined information is obtained by decoding, the control unit 21 communicates a return instruction for returning the control method of the screen display of the information code C by the display unit 33 changed by the display control information to the original control method. It is transmitted via the unit 27 (S313). In addition, when a return instruction is received via the communication unit 36, the control unit 31 returns the control method for the screen display of the information code C by the display unit 33 changed based on the display control information to the original control method. (S411).

  Thereby, after temporarily changing the control method of the screen display of the information code C in the portable terminal 30 based on the display control information, it is possible to automatically return to the state before the change. Therefore, it is not necessary for the user to perform the operation of returning the control method of the screen display of the information code C to the state before the change, and the user is aware that the control method of the screen display of the information code C is changed. There is no need to do this.
