<System overview>
FIG. 1 is a schematic diagram for explaining the outline of the trading system according to the present embodiment. The trading system according to the present embodiment is configured to include one or a plurality of information processing devices such as the portable information processing device 1 or the stationary information processing device 2, the sales server device 3, and the settlement server device 5. Yes. The portable information processing device 1 and the stationary information processing device 2 are devices that a user uses when purchasing a product. The portable information processing device 1 is a device such as a portable game device, a mobile phone, a smartphone, a tablet terminal device, or a laptop computer. The stationary information processing device 2 is a device such as a stationary game device, a desktop personal computer, or a tower personal computer. The portable information processing device 1 and the stationary information processing device 2 can communicate with the sales server device 3 and the settlement server device 5 via a wired or wireless network, respectively. The portable information processing device 1 and the stationary information processing device 2 according to the present embodiment have a non-contact communication function and can communicate with the IC card 7.

  In the trading system according to the present embodiment, the sales server device 3 sells products or rights via a network, and the user uses the portable information processing device 1 or the stationary information processing device 2 to sell products or rights. This is a so-called online buying and selling system for making purchases. That is, in the trading system according to the present embodiment, the consumer and the purchaser (consumer) do not face each other, and the consumer uses the portable information processing device 1 or the stationary information processing device 2 to connect the network such as the Internet. This is a system for purchasing goods or services via Therefore, the portable information processing device 1 and the stationary information processing device 2 are not store-installed devices but non-face-to-face devices. That is, the portable information processing device 1 and the stationary information processing device 2 are not devices that are operated by a seller of goods or rights, but are devices that are operated by a purchaser of goods or rights.

  The goods sold by the sales server device 3 may be various articles such as books or electronic devices delivered to the user's home or the like later by mail or the like. The product may be any service provided to a purchased user, for example. The product is digital such as software or data (including item data that can be used only within specific software) downloaded to the portable information processing device 1 or the stationary information processing device 2 or another device upon purchase. It may be content or various other things.

  The right to be sold by the sales server device 3 is a right to use the virtual currency in a service in which the server device mainly manages increase / decrease of numerical information (for example, balance information, etc.) such as a virtual currency service. For example, the virtual currency or points used in a specific sales site or game, etc. are given to the user by an amount corresponding to the consideration (for example, the amount paid by the user), thereby the virtual currency or points. Etc. can be sold to users. In the following, a product or a right sold by the sales server device 3 is simply referred to as a product.

  When the product sold by the sales server device 3 is digital content, the portable information processing device 1 and the stationary information processing device 2 can download and use the purchased digital content. Examples of digital content include video works such as movies or television broadcasts, games, applications, databases, websites, program software, text data, comics, music, animation, photographs, art, computer graphics, or characters. For example, when a video product is purchased as digital content, the portable information processing device 1 or the stationary information processing device 2 downloads the video data of this video product from the sales server device 3 or another server device, and the video data is downloaded. It is possible to perform processing for reproduction and display on a display unit or the like. Digital content such as video works or music may be provided by so-called streaming distribution. For example, when a game is purchased as digital content, the portable information processing device 1 or the stationary information processing device 2 can download and execute a game program, data, and the like. Thus, the portable information processing apparatus 1 and the stationary information processing apparatus 2 can perform processing for using the purchased digital content.

  Further, for example, a product sold by the sales server device 3 may be a virtual currency. For example, the virtual currency includes points and virtual coins that can be used to purchase products on a specific website, or points and virtual coins that can be used to purchase items or additional scenarios in a specific game. The portable information processing device 1 and the stationary information processing device 2 can purchase virtual currency in the sales server device 3 and purchase products using the virtual currency in a specific website or game. .

  In the buying and selling system according to the present embodiment, a user who purchases a product can use the IC card 7 for payment. The user can charge electronic money, points, or the like that can be used to purchase a product, for example, at a store. The IC card 7 may be used in combination with a card used for payment of fares in public transportation such as a train or a bus. The IC card 7 stores a balance of charged electronic money or points in an internal memory or the like. The IC card 7 has a non-contact communication function, and can perform payment processing with the payment server device 5 via the portable information processing device 1 or the stationary information processing device 2.

  Hereinafter, the case where the user uses the portable information processing apparatus 1 will be described, but the same applies to the case where the stationary information processing apparatus 2 is used. A user who uses online sales first operates the portable information processing apparatus 1 to access the sales server apparatus 3 and performs login processing for the system. By this login process, a trading process (a sales process by the sales server apparatus 3 and a purchase process by the portable information processing apparatus 1) by the trading system according to the present embodiment is started. When the login is successful, information such as a list of products sold for sale is transmitted from the sales server device 3 to the portable information processing device 1, and a list of products that can be purchased is displayed on the display unit of the portable information processing device 1. Is done. The user operates the portable information processing device 1 to select a product to purchase, and gives a purchase request to the sales server device 3 (see (1) in the figure). The sales server device 3 to which the purchase request is given from the portable information processing device 1 calculates the total price of the product to be purchased, and transmits a payment request for this amount to the portable information processing device 1 as a settlement request. (See (2a) in the figure). The portable information processing device 1 that has received the payment request from the sales server device 3 transmits the received payment request to the payment server device 5 (see (2b) in the figure).

  The payment server device 5 that has received the payment request from the portable information processing device 1 communicates with the IC card 7 owned by the user via the portable information processing device 1, and the merchandise from the balance stored in the IC card 7. A process of reducing the amount corresponding to the price (settlement execution process) is performed (see (3a) and (3b) in the figure). (Note that, as will be described later, when the balance is stored and managed in the settlement server device 5 without storing the balance in the IC card 7, the processing for deducting the balance from the balance of the IC card 7 is not performed here. Processing for reducing the amount corresponding to the product price from the balance is performed.) At this time, the portable information processing device 1 urges the IC card 7 used for payment to be close to a predetermined location of the portable information processing device 1, for example. A message or the like is displayed on the display unit, and non-contact communication with the IC card 7 is performed. The portable information processing device 1 transmits information received from the settlement server device 5 to the IC card 7 and transmits information received from the IC card 7 to the settlement server device 5. Communication between the settlement server device 5 and the IC card 7 via the portable information processing device 1 is performed a plurality of times, whereby the product price is reduced from the balance of the IC card 7.

  The settlement server device 5 that has finished the communication with the IC card 7 transmits the result of the settlement process to the portable information processing device 1 (see (4a) in the figure). When the product price can be reduced from the balance of the IC card 7, a result indicating that the payment process has been successful is transmitted. On the other hand, if the product price cannot be reduced due to a shortage of balance or a failure in communication, a result indicating that the payment process has failed is transmitted. The portable information processing device 1 that has received the payment result from the payment server device 5 transmits the received payment result to the sales server device 3 (see (4b) in the figure). With the transmission of the settlement result, the settlement process by the trading system according to the present embodiment is completed. The sales server device 3 performs further processing for selling the product based on the settlement result received from the portable information processing device 1. For example, if the settlement process is successful, the sales server device 3 determines that the price of the product to be sold has been paid, and proceeds with the buying and selling process to a stage such as preparation for shipping the product or permission to download. For example, when the payment process has failed, the sales server apparatus 3 notifies the portable information processing apparatus 1 that the payment process has failed or that the payment process is to be performed again. Note that the buying and selling process by the buying and selling system according to the present embodiment is terminated when the user logs out of the system, for example.

  As described above, in the trading system according to the present embodiment, the sales server device 3 and the settlement server device 5 do not communicate directly, but communicate via the portable information processing device 1. For this reason, there is no fear that the sales process fails due to a communication failure between the sales server apparatus 3 and the settlement server apparatus 5, and a smooth sales process can be realized. However, this system configuration is an example, and the present invention is not limited to this. For example, the sales server device 3 transmits a payment request directly to the payment server device 5, the payment server device 5 performs a reduction process for the IC card 7 via the portable information processing device 1, and the payment server device 5 The configuration may be such that the settlement result is directly transmitted to the device 3. Further, for example, the settlement server device 5 may be configured to perform a reduction process for the IC card 7 via the sales server device 3 and the portable information processing device 1. The trading system may have a configuration other than these.

  Further, in the trading system according to the present embodiment, a function for preventing unauthorized access (data read / write, etc.) to the IC card 7 is installed in the portable information processing apparatus 1. In the present embodiment, the stationary information processing apparatus 2 is not equipped with an unauthorized access prevention function. This is because the portable information processing device 1 can be easily carried by the user and can be illegally used compared to the stationary information processing device 2. However, the stationary information processing apparatus 2 may have a similar unauthorized access prevention function.

The unauthorized access prevention function provided in the portable information processing apparatus 1 according to the present embodiment includes the following three.
(1) Restriction of device posture (2) Restriction of waiting time for communication with IC card 7 (3) Restriction of communication distance with IC card 7

(a) Before the payment process is executed, the payment process is prevented from being executed by preventing the shift to the payment process. For example, in a process for requesting an operation for confirming a purchased product, a process for confirming the detection result of the detection unit may be executed so that the confirmation operation for the purchased product is not accepted. For example, when the portable information processing device 1 enters a standby state for non-contact communication for contactless communication with the IC card 7 in response to a read command from the settlement server device 5, the standby state is suspended (suspended) The processing of (a) may also be included in the processing (a).
(b) A process of restricting the payment process by stopping (including holding, the same applies hereinafter) or terminating the payment process by executing a process of confirming the detection result of the detection unit during the execution of the payment process. For example, a payment method selection operation may not be accepted by executing a process of confirming a detection result of the detection unit in a process of requesting an operation for selecting a payment method.
(c) The settlement process is restricted by stopping or terminating the settlement process by executing a process for confirming the detection result of the detection unit during the settlement process. For example, during the execution of the IC card reading process and / or during the communication for settlement with the settlement server, the settlement process is stopped or terminated by executing the process of confirming the detection result of the detection unit. To limit payment processing.
(d) A process for restricting the settlement process by canceling the settlement process after the settlement process is completed.

  The sales server device 3 that has received the purchase request from the portable information processing device 1 by the communication unit 33 generates the transaction ID for the processing such as sale and settlement of the product related to the received purchase request by the ID generation unit 42. . The sales processing unit 41 of the sales server device 3 creates a payment request including information such as a transaction ID, payment date / time information, product price information, and electronic signature, and transmits the payment request to the portable information processing device 1 by the communication unit 33. . Thereby, the settlement process in the buying and selling process is started.

  In addition, the sales processing unit 41 of the sales server device 3 that has received the purchase request adds information to the sales history information 31 a in the storage unit 31. The sales processing unit 41 associates the transaction ID generated by the ID generation unit 42 with the user ID, product information and total amount generated or acquired from the information included in the received purchase request, and the date and time when the payment request was made. And stored in the sales history information 31a. At this time, the settlement result of the corresponding sales history information 31a has not been received, and the sales processing status has not been completed.

  The payment processing unit 21 of the portable information processing device 1 that has received the payment request from the sales server device 3 through the communication unit 15 transmits the received payment request to the payment server device 5 through the communication unit 15. Thereby, transaction processing related to payment is started between the portable information processing device and the payment server device.

  Payment server device 5 that has received the payment request from portable information processing device 1 generates an update ID in ID generation unit 62. The settlement processing unit 61 of the settlement server device 5 adds information to the settlement history information 51a in the storage unit 51. The settlement processing unit 61 stores the transaction ID and settlement date / time included in the received settlement request and the update ID generated by the ID generation unit 62 in the settlement history information 51a. At this time, the settlement state of the corresponding settlement history information 51a is not settled, and the card ID is undetermined.

  Next, the settlement processing unit 61 of the settlement server device 5 acquires the amount information included in the received settlement request and starts a process of reducing this amount from the balance of the IC card 7. The settlement processing unit 61 gives a read command of the IC card 7 to the portable information processing apparatus 1 in order to specify the IC card 7 used for the settlement process. At this time, the settlement processing unit 61 designates a waiting time until a response is obtained from the portable information processing device 1 (that is, a waiting time until contactless communication with the IC card 7 is performed). In the present embodiment, the standby time can be set to 60 seconds, for example, and the standby time specified by the settlement server device 5 can be either the portable information processing device 1 or the stationary information processing device 2. It is the same time. If a response from the portable information processing device 1 cannot be obtained within the standby time, the payment processing unit 61 interrupts the reduction process for the payment request given from the portable information processing device 1.

  The payment processing unit 21 of the portable information processing device 1 that has received the read command from the payment server device 5 performs non-contact communication with the IC card 7 by the non-contact communication unit 16. At this time, the settlement processing unit 21 displays a message on the display unit 13 for prompting the user to perform an operation such as bringing the IC card 7 close to a predetermined location of the portable information processing device 1. Execute standby processing that waits until it becomes possible. That is, the settlement processing unit 21 executes standby processing for waiting for the proximity of the IC card 7 to a predetermined location of the portable information processing device 1. In the standby process, the non-contact communication unit 16 repeatedly transmits the read command by the polling function until a response from the IC card 7 is obtained.

  At this time, the settlement processing unit 21 interrupts the reduction process if the contactless communication with the IC card 7 cannot be performed even after the predetermined standby time has elapsed. Note that the waiting time at this time is the waiting time (60 seconds) designated by the settlement server device 5 in the case of the stationary information processing apparatus 2. On the other hand, in the portable information processing device 1, a time shorter than the standby time designated from the settlement server device 5, for example, 30 seconds is set as the standby time.

  If non-contact communication with the IC card 7 becomes possible before the standby time elapses, the settlement processing unit 21 of the portable information processing device 1 transmits a read command to the IC card 7 by non-contact communication. The reader unit 28 of the processing unit 10 performs a process of transmitting a read command. The payment processing unit 21 transmits a response obtained from the IC card 7 to the payment command to the payment server device 5. The payment processing unit 61 of the payment server device 5 that has received the response from the portable information processing device 1 acquires the read information included in the received response. The settlement processing unit 61 reads information from the IC card 7 a plurality of times and acquires information such as the card ID 73 a and the balance stored in the storage unit 73 of the IC card 7. When the payment processing unit 61 acquires the card ID 73 a from the IC card 7, it registers the card ID in the payment history information 51 a of the storage unit 51. Thereafter, the settlement processing unit 61 designates the card ID 73a and makes a read request to the IC card 7 to the portable information processing apparatus 1.

  The payment processing unit 61 of the payment server device 5 that has acquired the necessary information from the IC card 7 sends a write command to the portable information processing device in order to write in the IC card 7 the amount obtained by reducing the product price from the balance of the IC card 7. Send to 1. Further, the settlement processing unit 61 changes the corresponding settlement state of the settlement history information 51a in the storage unit 51 to processing incomplete. The payment processing unit 21 of the portable information processing device 1 that has received the write command from the payment server device 5 performs non-contact communication with the IC card 7 by the non-contact communication unit 16 and sends the write command to the IC card 7. Send. The writer unit 29 of the processing unit 10 performs processing for transmitting a write command. The processing unit 70 of the IC card 7 performs a writing process to the storage unit 73 in accordance with the write command received from the portable information processing device 1 by non-contact communication. Thereby, the balance history information 73b of the storage unit 73 is updated. After completion of the writing process, the processing unit 70 of the IC card 7 makes a response to the portable information processing device 1 by non-contact communication. The settlement processing unit 21 of the portable information processing device 1 that has received the response from the IC card 7 by non-contact communication transmits the received response to the settlement server device 5.

  The payment processing unit 61 of the payment server device 5 that has received the response from the portable information processing device 1 determines whether or not the information writing of the IC card 7 has been successful from the received response. FIG. 9 shows a case where the writing process to the IC card 7 is successful. When the writing process has failed, the settlement processing unit 61 may repeatedly transmit the writing request to the portable information processing device 1 until the writing process is successful. When the writing process is successful, the settlement processing unit 61 changes the corresponding settlement state of the settlement history information 51a in the storage unit 51 to settlement successful. Further, the settlement processing unit 61 notifies the portable information processing device 1 of the completion of the settlement process.

  The payment processing unit 21 of the portable information processing device 1 that has received the completion notification from the payment server device 5 ends the non-contact communication with the IC card 7 by the non-contact communication unit 16 and a response that the completion notification has been received. Is transmitted to the settlement server device 5. The payment processing unit 61 of the payment server device 5 that has received the response from the portable information processing device 1 generates a payment result including the result of the payment processing (successful payment in this example) as information, and the generated payment result is carried by the mobile phone. Type information processing apparatus 1. Note that, for example, when the payment process cannot be performed normally due to an insufficient balance of the IC card 7, the payment server device 5 transmits a result of the payment failure. Further, for example, when a time-out occurs because a response from the IC card 7 cannot be obtained, the settlement server device 5 transmits a result of incomplete processing.

  The settlement processing unit 21 of the portable information processing device 1 that has received the settlement result from the settlement server device 5 transmits the received settlement result to the sales server device 3 through the communication unit 15. When the sales server device 3 receives the settlement result, the settlement process is completed. The sales server device 3 that has received the settlement result from the portable information processing device 1 updates the settlement result of the sales history information 31a in the storage unit 31 to the completion of settlement, settlement failure, or incomplete processing based on the received settlement result. . If the settlement result is a successful settlement, the sales processing unit 41 advances the product sales process to the next process. For example, when the product is digital content, the sales processing unit 41 permits downloading of the digital content. After performing the sales process, the sales processing unit 41 transmits the sales result to the portable information processing apparatus 1. When the portable information processing device 1 receives the sales result from the sales server device 3, the product sales and settlement processing by the trading system according to the present embodiment is completed. As a result, transaction processing relating to payment between the portable information processing device and the payment server device ends.

The “settlement process” is a process related to settlement of purchased products and rights, and is used for communication between the portable information processing device 1 and the settlement server device 5 (in addition, communication between the terminal device and the settlement server device). The process performed in each of the other terminal apparatus and server apparatus which intervene is included. That is, the “settlement process” is not necessarily a process performed in cooperation between the portable information processing apparatus 1 and the settlement server apparatus 5, but is a process performed in the portable information processing apparatus 1 (locally). Alternatively, the processing performed in the settlement server device 5 may be used. Further, the payment process may be a process related to payment of purchased products and rights, and may include a process related to preparation for making a payment. For example, when various types of data used for making a payment are read from the IC card 7 (in response to a request from the payment server device 5), a standby process that waits until non-contact communication with the IC card 7 becomes possible is also made. Can be included in the processing related to the preparation for performing (i.e., included in the settlement processing).

  In the buying and selling system according to the present embodiment, a process of restricting non-contact communication with the IC card 7 is performed as an unauthorized access prevention function of the portable information processing apparatus 1. In the present embodiment, portable information processing device 1 is a period from the time when a read command is received from settlement server device 5 until the first response by non-contact communication from IC card 7 is transmitted to settlement server device 5. Is the limit period, and the limit process is performed during this period. In other words, in the buying and selling process and the settlement process according to the present embodiment, a restriction period (first period) for restricting non-contact communication and a period (second period) in which no restriction other than the restriction period is performed. Is provided.

  However, the limited period shown in FIG. 9 is an example, and the present invention is not limited to this. For example, the start time of the limited period is the time when the portable information processing device 1 transmits a purchase request to the sales server device 3, the time when the portable information processing device 1 receives a settlement request from the sales server device 3, or the mobile It may be a time when the type information processing device 1 transmits a payment request to the payment server device 5 or may be a time other than these. Further, for example, when the limit period ends, the last response from the IC card 7 is transmitted to the settlement server device 5 by the portable information processing device 1 or the completion notification from the settlement server device 5 is transmitted to the portable information processing device. 1 may be the time when received from the settlement server device 5 or the like, or may be a time other than these. In the present embodiment, the portable information processing device 1 performs three types of restrictions, but different restriction periods may be provided.

  In the present embodiment, the portable information processing device 1 relays the payment request and the payment result transmitted and received between the sales server device 3 and the payment server device 5, but the present invention is not limited to this. . The sales server device 3 and the payment server device 5 may directly transmit and receive a payment request and a payment result without using the portable information processing device 1.

  In the present embodiment, the reduction process is performed by reducing the balance information stored in the IC card 7, but the present invention is not limited to this. For example, the settlement server device 5 stores balance information for each IC card 7, and performs self-contact communication with the portable information processing device 1, based on the card ID acquired from the IC card 7. It is good also as a structure which performs reduction from the balance information memorize | stored. In this case, the settlement server device 5 may register the balance information regarding the IC card 7 when the IC card 7 is used for the first time, or the balance information has been registered before the IC card 7 is used. May be. Further, for example, both the IC card 7 and the settlement server 5 may be configured to store balance information. In this case, the settlement server device 5 can detect illegal rewriting of the balance information of the IC card 7 by determining whether or not the balance information of the IC card 7 matches the balance information stored by the confidence. .

<Screen display of transaction processing>
FIG. 10 is a schematic diagram illustrating an example of a payment method selection screen displayed by the portable information processing device 1. For example, the user selects a product to be purchased by appropriately operating the operation unit 14 with respect to a product list displayed on the display unit 13 of the portable information processing device 1 and decides to purchase the selected product. It can be performed. When this purchase determination operation is performed, the display processing unit 25 of the portable information processing device 1 displays the payment method selection screen illustrated in FIG. 10 on the display unit 13. In the illustrated payment method selection screen, three payment method options are displayed together with a message “Please select a payment method”. The user can select one of payment using a credit card, reduction of electronic money charged in the IC card 7, or payment using a prepaid card. When a cancel operation is performed on this screen, the display processing unit 25 returns the display to a previous screen such as a purchase decision confirmation screen or a list screen of sales products.

  When electronic money is selected on the payment method selection screen, the display processing unit 25 of the portable information processing device 1 displays a warning message regarding the device posture on the display unit 13. FIG. 11 is a schematic diagram illustrating an example of a warning message display screen displayed by the portable information processing device 1. On the illustrated warning message display screen, a message “Please place the main body on a horizontal surface when using an IC card” is displayed. Thereby, the portable information processing device 1 requests the user to perform a predetermined operation, that is, an operation for OK on the warning message display screen before starting non-contact communication with the IC card 7. When a cancel operation is performed on this screen, the display processing unit 25 returns the display to the payment method selection screen shown in FIG.

  When an OK operation is performed on the warning message display screen, the purchase processing unit 26 of the portable information processing device 1 transmits a purchase request to the sales server device 3 as shown in FIG. The payment processing unit 21 transmits the payment request given from the server device 3 to the payment server device 5. Thereafter, when a read command is given from the settlement server device 5, the settlement processing unit 21 of the portable information processing device 1 starts contactless communication by the contactless communication unit 16 and performs contactless communication with the IC card 7. stand by. At this time, the display processing unit 25 displays on the display unit 13 a standby screen for waiting for the user to use the IC card 7.

  FIG. 12 is a schematic diagram illustrating an example of a standby screen displayed by the portable information processing device 1. In the illustrated standby screen, a message “Please touch the IC card to this screen” is displayed. When the user brings the IC card 7 close to the display unit 13 while the standby screen is displayed, the portable information processing device 1 can perform non-contact communication with the IC card 7 by the non-contact communication unit 16. It becomes. When a cancel operation is performed on the standby screen, the display processing unit 25 returns the display to the payment method selection screen shown in FIG. Note that for communication with the IC card 7 by the non-contact communication unit 16, it is not always necessary to bring the IC card 7 into contact with the display unit 13, but the IC card 7 is brought close to the display unit 13 to such an extent that radio waves can reach in both directions. You can attach it. However, in order to make the user easily understand how to use the IC card 7, in the present embodiment, a message prompting the user to touch the display unit 13 of the IC card 7 is displayed on the standby screen.

  When it is possible to perform non-contact communication with the IC card 7, the portable information processing device 1 relays information exchange between the IC card 7 and the settlement server device 5. Thereby, the reduction process shown in FIG. 9 is performed. After the reduction processing is completed, the portable information processing device 1 is configured such that the payment processing unit 21 notifies the sales server device 3 of the payment result from the payment server device 5 and notifies the user of the payment result (not shown). ) Is displayed on the display unit 13 by the display processing unit 25. Since the settlement result may have various patterns such as successful or unsuccessful settlement, the display processing unit 25 displays a message corresponding to the settlement process.

  The portable information processing device 1 may output various voice messages by the voice output unit 18 together with the screen display of the display unit 13. Further, the portable information processing device 1 may be configured to output only a voice message by the voice output unit 18 without performing screen display.

<Attitude restriction>
The portable information processing device 1 according to the present embodiment restricts the posture of the device when performing non-contact communication with the IC card 7 as a function for preventing unauthorized access to the IC card 7. 13 and 14 are schematic diagrams for explaining posture restriction by the portable information processing device 1. The portable information processing apparatus 1 according to the present embodiment is assumed to perform non-contact communication with the IC card 7 in a state where the portable information processing apparatus 1 is placed on a horizontal surface 100 such as a desk or a floor.

  As illustrated, the portable information processing device 1 has a substantially rectangular plate-shaped casing. That is, the casing of the portable information processing apparatus 1 has a shape having two wide surfaces on the front and back sides and four surrounding side surfaces. On one wide surface of the housing (this surface is referred to as the front surface), a display unit 13 is provided in the center, and one or a plurality of buttons or switches constituting the operation unit 14 are provided in the periphery thereof. In the non-contact communication unit 16 of the portable information processing 1 according to the present embodiment, for example, an antenna for non-contact communication is arranged on the surface of the liquid crystal panel constituting the display unit 13, and a predetermined distance from the surface of the display unit 13. Non-contact communication with the IC card 7 can be performed within the range. However, in the portable information processing 1 according to the present embodiment, the other wide surface (back surface) and the four side surfaces of the housing are shielded from radio waves for non-contact communication, and the IC card 7 is brought close to the portable information processing 1. However, it is configured such that non-contact communication cannot be performed.

  The portable information processing device 1 according to the present embodiment can detect the posture of the device by the posture detection unit 17. The posture restriction unit 22 of the portable information processing device 1 permits non-contact communication with the IC card 7 by the non-contact communication unit 16 when the posture of the device detected by the posture detection unit 17 is a predetermined posture. When the posture of the apparatus is not a predetermined posture, the posture restriction unit 22 prohibits non-contact communication with the IC card 7. The posture restriction unit 22 can realize prohibition of non-contact communication by ending or stopping the standby process for waiting for a response from the IC card 7. At this time, the posture restriction unit 22 may end the standby process completely, or may temporarily interrupt the standby process.

  In the present embodiment, the posture detection unit 17 is a wide surface of a housing provided with the display unit 13 or the like (that is, a surface that performs non-contact communication with the IC card 7 or a surface on which the user contacts the IC card 7). Hereinafter, the angle of the contactless communication surface) with respect to the direction of gravity is detected. Based on the detection result of the posture detection unit 17, the posture restriction unit 22 is not connected to the IC card 7 by the non-contact communication unit 16 when the non-contact communication surface of the housing is facing upward and substantially horizontal. Allow contact communication. Specifically, the posture restriction unit 22 is a non-contact communication unit when the non-contact communication surface of the housing faces the direction opposite to the gravity direction and the angle of the non-contact communication surface is horizontal ± 15 °. 16, the non-contact communication with the IC card 7 is permitted, and the non-contact communication with the IC card 7 is prohibited when it is outside the range of horizontal ± 15 °.

  In the present embodiment, the posture condition restricted by the posture restriction unit 22 is set so that the non-contact communication surface is upward and the angle of the non-contact communication surface is within a range of horizontal ± 15 °. This condition is a condition set for determining that the portable information processing apparatus 1 having the shape shown in FIGS. 13 and 14 is placed in a horizontal place. For this reason, the condition of the posture to perform the restriction is an appropriate condition that can determine that the casing is placed in a horizontal place according to the shape of the casing of the portable information processing device 1 or the like. Can be set.

  For example, the IC card 7 may be placed on a horizontal place, and the posture restriction may be performed on the condition that the portable information processing device 1 is placed thereon. In this case, for example, the posture restriction unit 22 performs the determination on the condition that the non-contact communication surface is directed in the gravity direction (that is, the downward direction) and the non-contact communication surface is within a range of ± 15 ° in the horizontal direction. It can be configured.

  The posture restriction unit 22 of the portable information processing device 1 detects the posture after the operation detection unit 30 detects that a predetermined operation on the operation unit 14, for example, an OK operation is performed on the warning message display screen illustrated in FIG. Acquisition of the detection result of the detection unit 17 and determination of the posture based on the acquired detection result are started. In the portable information processing device 1, after the processing such as determination by the posture restriction unit 22 is started, the settlement processing unit 21 starts non-contact communication by the non-contact communication unit 16 and the display processing unit 25 waits as shown in FIG. 12. The screen is displayed on the display unit 13. While the standby screen is displayed, the posture restriction unit 22 continuously performs the acquisition of the detection result of the posture detection unit 17 and the determination of the posture based on the acquired detection result. During this time, the non-contact communication unit 16 continuously detects the IC card 7 by polling.

  When it is determined that the device posture is the predetermined posture, the posture restriction unit 22 is in the portable information processing device 1 until the non-contact communication unit 16 starts the non-contact communication with the IC card 7. Is maintained in a non-contact communication standby state (for example, polling state). As a result, as shown in FIG. 12, the state where the standby screen is displayed on the display unit 13 of the portable information processing device 1 is maintained.

  On the other hand, when it is determined that the device posture is not the predetermined posture, the posture restriction unit 22 interrupts the standby state of non-contact communication with the IC card 7. That is, the attitude restriction unit 22 stops polling by the non-contact communication unit 16. Thereby, the settlement processing unit 21 of the portable information processing device 1 stops the non-contact communication by the non-contact communication unit 16. Further, the display processing unit 25 returns the display of the display unit 13 from the standby screen shown in FIG. 12 to the warning message display screen shown in FIG. Thereby, the portable information processing device 1 requests a predetermined operation on the warning message display screen (for example, an operation for selecting OK again on the warning message display screen), and when the predetermined operation by the user is received, the IC card 7 The standby process resuming unit 27 of the processing unit 10 resumes the standby process for the non-contact communication with. Note that the method for requesting the user to perform a predetermined operation is not limited to this method. For example, the user is prompted to place the portable information processing device 1 in a predetermined posture or a stationary state (described later). A message (different from the warning message display screen shown in FIG. 11) may be displayed.

  FIG. 15 is a flowchart illustrating a procedure of posture restriction processing by the portable information processing device 1. The processing unit 10 of the portable information processing apparatus 1 displays a warning message display screen on the display processing unit 25 when, for example, electronic money is selected as the payment method on the payment method selection screen shown in FIG. 13 is displayed (step S1). The processing unit 10 determines whether an OK operation has been performed on the warning message display screen (step S2). When the OK operation has not been performed (S2: NO), the processing unit 10 returns the process to step S1 and continues to display the warning message display screen.

  When the OK operation is performed (S2: YES), the processing unit 10 performs a process of displaying a standby screen on the display unit 13 in the display processing unit 25 (step S3). Next, the posture restriction unit 22 of the processing unit 10 acquires the device posture detected by the posture detection unit 17 (step S4). The posture restriction unit 22 determines whether or not the acquired posture is a predetermined posture (step S5). When the device posture is not a predetermined posture (S5: NO), the posture restriction unit 22 interrupts the standby state of non-contact communication with the IC card 7 (step S6), returns the process to step S1, and displays the display processing unit. The display process of the warning message display screen 25 on the display unit 13 is performed. When the device posture is a predetermined posture (S5: YES), the posture restriction unit 22 determines whether or not non-contact communication with the IC card 7 by the non-contact communication unit 16 is started (step S7). When the non-contact communication has not been started (S7: NO), the posture restriction unit 22 returns the process to step S3 and continues to display the standby screen. When the non-contact communication is started (S7: YES), the posture restriction unit 22 ends the posture restriction process.

(Modification 1)
In the present embodiment, the posture restriction unit 22 is configured to restrict the non-contact communication with the IC card 7 when the non-contact communication surface of the housing is not within the range of horizontal ± 15 °. Is not limited to this. (Also, it may not be ± 15 °, and may be ± number of times as long as it can be said to be a substantially horizontal state.) For example, the posture restriction unit 22 is a housing of the portable information processing apparatus 1. It can be set as the structure which restrict | limits according to whether a body is a stationary state. The posture restriction unit 22 according to the first modification is based on the posture first acquired from the posture detection unit 17 after the OK operation is performed on the warning message display screen and the state is shifted to the standby state. After that, the posture restriction unit 22 repeatedly acquires the detection result of the posture detection unit 17 and waits for non-contact communication with the IC card 7 when the change in posture from the reference posture exceeds a threshold value (predetermined limit). Suspend the state.

  Furthermore, the posture restriction unit 22 may be configured to perform posture restriction processing under various conditions. For example, the posture limiting unit 22 detects postures at a predetermined cycle instead of a change from the reference posture, and interrupts the standby state for non-contact communication when the difference between the previous posture and the current posture exceeds a threshold value. It is good. That is, the posture restriction unit 22 may be configured to interrupt the standby state when the movement of the portable information processing device 1 exceeds a predetermined limit.

  Further, for example, the portable information processing device 1 may be configured to perform posture detection and posture limitation based on a captured image such as a camera or an image sensor. In this case, the posture restriction unit 22 compares a plurality of images obtained by periodically performing imaging, calculates the amount of displacement of an object captured in the image, etc. by image processing, and compares it with a threshold value. It can be set as the structure which performs.

  Further, for example, when a camera is mounted on the back surface of the casing of the portable information processing device 1, the above-described portable information processing device 1 indicates that the desk surface or the floor surface is captured by the camera. You may add to the conditions for determining that it is mounted in the surface or the floor surface.

  Further, for example, the posture may be limited on the condition that the non-contact surface of the housing is maintained in a substantially horizontal state for a predetermined period. For example, the portable information processing device 1 confirms that a substantially horizontal state is maintained for a predetermined period (for example, 15 seconds) after an OK operation is performed on the warning message display screen, and then performs non-contact communication. It can be set as the structure which starts communication with the IC card 7 by the part 16. FIG.

  In the present embodiment, the posture restriction unit 22 performs posture restriction in a payment process performed by the payment processing unit 21. The posture restriction unit 22 does not restrict processing (non-payment processing) other than the payment processing performed by the purchase processing unit 26. The portable information processing apparatus 1 may be configured not to detect the posture by the posture detection unit 17 while performing non-payment processing. The posture detection unit 17 performs posture detection, but the detection result is processed by the processing unit. 10 may be configured, the processing unit 10 may ignore the detection result notified by the posture detection unit 17, or the posture restriction unit 22 may determine the posture condition based on the detection result. The structure which does not perform may be sufficient.

<Standby time limit>
The portable information processing device 1 according to the present embodiment limits the waiting time until the start of non-contact communication with the IC card 7 as a function for preventing unauthorized access to the IC card 7. As shown in FIG. 9, in the trading system according to the present embodiment, the waiting time is specified when the IC card 7 is read from the settlement server device 5 to the portable information processing device 1 or the stationary information processing device 2. I do. In the present embodiment, the waiting time specified by the settlement server device 5 is the same time regardless of whether the other party of the settlement processing is the portable information processing device 1 or the stationary information processing device 2, for example, 60 seconds. can do.

  When the waiting time is designated from the settlement server device 5, the stationary information processing device 2 waits for non-contact communication with the IC card 7 for the designated waiting time. If the non-contact communication with the IC card 7 is not performed within this waiting time, the stationary information processing apparatus 2 interrupts the settlement process. In addition, the settlement server device 5 interrupts the settlement process when a response from the stationary information processing device 2 is not obtained within the designated waiting time.

  On the other hand, in the portable information processing device 1 according to the present embodiment, a time shorter than the standby time specified from the settlement server device 5 is set as a standby time for waiting for non-contact communication with the IC card 7. . For example, while the standby time specified by the server device 5 is 60 seconds, the standby time of the portable information processing device 1 can be set to 30 seconds. Note that the standby time of the portable information processing device 1 may be a time determined in advance in the trading system, or may be a time calculated by calculation such as 50% of the standby time designated by the server device 5.

  After the electronic money is selected on the payment method selection screen shown in FIG. 10 and the OK operation is performed on the warning message display screen shown in FIG. Start timing the waiting time. While the standby screen shown in FIG. 12 is displayed on the display unit 13, the time limiter 23 continues to count the standby time. When the non-contact communication with the IC card 7 is not performed within the waiting time, the time limiter 23 interrupts the settlement process. When the settlement process is interrupted, the portable information processing 1 according to the present embodiment returns the display on the display unit 13 to the payment method selection screen shown in FIG. That is, when the payment process is interrupted, the payment processing unit 21 of the portable information processing 1 according to the embodiment returns the buying and selling process until the payment method selection stage.

  Note that the portable information processing device 1 displays a product selection screen (not shown) on a stage before the payment method selection screen, for example, a list of products that can be purchased, and a product selection operation by the user. The buying and selling process may be returned to the stage of accepting. The portable information processing device 1 returns the buying and selling process to a stage that requires at least one operation acceptance by the user before reaching the stage of performing non-contact communication with the IC card 7.

  FIG. 16 is a flowchart illustrating a procedure of standby time restriction processing by the portable information processing device 1. Note that this flowchart partially overlaps the flowchart shown in FIG. This is a flowchart of FIG. 16 in which the processing related to time restriction is extracted from the entire payment processing performed by the portable information processing device 1, and the flowchart of FIG. 15 is extracted from processing related to posture restriction. Because there is. Actually, the portable information processing device 1 performs the processing shown in FIGS. 15 and 16 simultaneously as one settlement processing.

  The processing unit 10 of the portable information processing device 1 performs processing for displaying the payment method selection screen illustrated in FIG. 10 on the display unit 13 by the display processing unit 25 (step S11). The processing unit 10 determines whether or not electronic money is selected as the payment method on the payment method selection screen (step S12). When the electronic money is not selected (S12: NO), the processing unit 10 returns the process to step S11 and continues to display the payment method selection screen. In addition, description is abbreviate | omitted about the process when another payment method is selected on the payment method selection screen.

  When electronic money is selected on the payment method selection screen (S12: YES), the processing unit 10 performs a process of displaying a warning message display screen on the display unit 13 in the display processing unit 25 (step S13). The processing unit 10 determines whether or not an OK operation has been performed on the warning message display screen (step S14). When the OK operation is not performed (S14: NO), the processing unit 10 returns the process to step S13 and continues to display the warning message display screen.

  When the OK operation is performed (S14: YES), the standby time limit unit 23 of the processing unit 10 starts measuring a predetermined standby time using, for example, a built-in timer function (step S15). Moreover, the process part 10 performs the process which displays a standby screen on the display part 13 in the display process part 25 (step S16). The standby time limiting unit 23 determines whether or not a predetermined standby time (for example, 30 seconds) has elapsed since the start of timing in step S15 (step S17). When the standby time has elapsed (S17: YES), the standby time restriction unit 23 returns the process to step S11, and returns the settlement process stage to the display of the payment method selection screen. At this time, the processing unit 10 may display a payment method selection screen after displaying an error message or the like.

  When the standby time has not elapsed (S17: NO), the standby time limiting unit 23 determines whether or not non-contact communication with the IC card 7 by the non-contact communication unit 16 has been started (step S18). When non-contact communication has not been started (S18: NO), the standby time restriction unit 23 returns the process to step S16 and continues to display the standby screen. When the non-contact communication is started (S18: YES), the standby time restriction unit 23 ends the standby time restriction process.

  In addition, as a method for limiting the standby time of non-contact communication with the IC card 7 by the portable information processing device 1, the methods shown in the following modified examples 2 to 3 can be employed.

(Modification 2)
The portable information processing apparatus 1 according to the modification 2 changes the standby time according to the type of application program executed by the processing unit 10. In the portable information processing 1 according to the present embodiment, the processing unit 10 executes various application programs stored in the storage unit 11 or the storage medium 91 in addition to the client program 91a for using the online trading system. can do. The portable information processing apparatus 1 can perform information processing related to a game, for example, by executing a game program. In this case, the portable information processing apparatus 1 can realize a game using a data storage medium such as an IC card or a figure in which an IC tag is embedded.

  When the portable information processing apparatus 1 according to the modification 2 performs non-contact communication with the data storage medium by the non-contact communication unit 16, the application program (non-contact with the data storage medium) executed by the processing unit 10 is performed. The standby time for waiting for non-contact communication with the data storage medium is changed according to the application program that requested communication. For example, the portable information processing device 1 stores a table in which the application program and the standby time are associated with each other in the storage unit 11, and determines the standby time by referring to this table based on the application program being executed. can do. The standby time is set to a short time (for example, 30 seconds) for an application program that performs a payment process with the payment server device 5, and is set to a long time (for example, 60 seconds) for an application program that does not perform a payment process. To do.

(Modification 3)
The portable information processing apparatus 1 according to the modification 3 changes the standby time according to the processing content even in the case of non-contact communication with the IC card 7 related to one client program 91a. The portable information processing apparatus 1 that executes the client program 91a can perform the settlement process with the settlement server apparatus 5 as described above by non-contact communication with the IC card 7, and for example, the balance inquiry of the IC card 7 In this way, processing that does not require communication with the settlement server device can be performed. The portable information processing device 1 according to the modified example 3 sets the standby time in the case of non-contact communication with the IC card 7 when performing payment processing with the payment server device 5 to a short time, and other than payment processing The standby time in the case of non-contact communication with the IC card 7 when performing is set to a long time.

(Modification 4)
The portable information processing apparatus 1 according to the modification 4 changes the standby time according to the type of the data storage medium that performs non-contact communication. For example, when the IC card 7 that can be used for payment processing by electronic money is provided by a plurality of companies, the portable information processing device 1 performs non-contact communication depending on which company's IC card 7 is used for payment processing. Change the waiting time.

  The portable information processing apparatus 1 according to the modified example 4 has an IC card 7 such as “electronic money of company A” or “electronic money of company B” on the payment method selection screen displayed on the display unit 13 in the payment process. Display options for each provider. The user performs an operation on the operation unit 14 of the portable information processing device 1 to select a provider of the IC card 7 to be used from among the options displayed on the payment method selection screen. The portable information processing device 1 is set with a standby time for each provider of the IC card 7, and determines the standby time according to the user's selection.

  Further, the portable information processing device 1 relates to the time for maintaining the non-contact communication with the IC card 7 as shown in the following modified example 5 in addition to (or separately from) the above-described standby time limit. Limits may be provided.

(Modification 5)
In the portable information processing device 1 according to the modified example 5, the state in which contactless communication with the IC card 7 is possible is a predetermined time as a condition for starting the payment processing with the payment server device 5 using the IC card 7. (E.g., 30 seconds). The portable information processing device 1 according to the modified example 5 has a predetermined period (for example, 1 second) when the non-contact communication unit 16 enables non-contact communication with the IC card 7 within the above-described standby time. It is determined whether or not non-contact communication with the IC card 7 is possible at one time). If the portable information processing device 1 determines that non-contact communication with the IC card 7 is possible for a predetermined number of times (for example, 30 times) continuously, the portable information processing device 1 proceeds to the next stage of the payment process.

  FIG. 17 is a flowchart illustrating a procedure of processing performed by the portable information processing device 1 according to the fifth modification. Note that the processing shown in this flowchart is processing that follows, for example, FIGS. 15 and 16. In this processing, a counter for counting the number of times of determination is used. This counter is realized by using, for example, an internal memory of the processing unit 10 or a part of a storage area of the storage unit 11.

  The processing unit 10 of the portable information processing device 1 according to the modification 5 first initializes the value of the counter to 0 (step S21). Next, the processing unit 10 performs non-contact communication with the IC card 7 in the non-contact communication unit 16 (step S22). The processing unit 10 determines whether or not communication with the IC card 7 is possible from the result of the non-contact communication in Step S22 (Step S23). When communication with the IC card 7 is impossible (S23: NO), the processing unit 10 interrupts the settlement process (step S24) and ends the process.

  When communication with the IC card 7 is possible (S23: YES), the processing unit 10 adds 1 to the value of the counter (step S25). Next, the processing unit 10 determines whether or not the counter value exceeds 30 (step S26). When the value of the counter does not exceed 30 (S26: NO), the processing unit 10 returns the process to step S22. When the value of the counter exceeds 30 (S26: YES), the processing unit 10 performs a subsequent settlement process (step S27) and ends the process.

<Communication distance restriction>
The portable information processing apparatus 1 according to the present embodiment limits a distance that allows non-contact communication with the IC card 7 as a function of preventing unauthorized access to the IC card 7. For example, in non-contact communication by NFC or the like, it is not necessary to bring the IC card 7 into contact with the casing of the portable information processing apparatus 1, and communication can be performed even if the distance is about several centimeters from the casing. When the portable information processing device 1 according to the present embodiment performs a payment process with the payment server device 5, the portable information processing device 1 performs non-contact communication by reducing the strength of the wireless signal output by the non-contact communication unit 16. The distance that can be performed is shorter than usual. For example, the portable information processing device 1 reduces the strength of the wireless signal when performing non-contact communication in the settlement process to about 50% of the strength of the wireless signal when performing contactless communication other than the settlement process.

  The non-contact communication unit 16 of the portable information processing device 1 according to the present embodiment can change the strength of the radio signal in accordance with a command from the processing unit 10. The non-contact communication part 16 changes the intensity | strength of a radio signal, for example in two steps. When the communication distance restriction unit 24 of the processing unit 10 performs non-contact communication with the IC card 7 in response to a read command from the settlement server device 5, a command for reducing the strength of the radio signal is sent to the non-contact communication unit 16. give. As a result, the strength of the wireless signal output from the non-contact communication unit 16 is reduced, and the distance over which the non-contact communication between the portable information processing device 1 and the IC card 7 can be shortened.

  FIG. 18 is a flowchart illustrating a procedure of communication distance restriction processing by the portable information processing device 1. The communication distance restriction unit 24 of the processing unit 10 of the portable information processing device 1 determines whether or not a request for access to the IC card 7 (that is, a read command) is given from the settlement server device 5 (step S31). When the request from the settlement server device 5 is not given (S31: NO), the communication distance restriction unit 24 stands by until the request is given. When the request from the settlement server device 5 is given (S31: YES), the communication distance restriction unit 24 gives a command to reduce the signal strength to the non-contact communication unit 16 (step S32).

  Thereafter, the communication distance restriction unit 24 determines whether or not the settlement process using the IC card 7 has been completed (step S33). Note that the end of the payment process here includes not only the normal end of the payment process but also an abnormal end such as a payment interruption for some reason. If the payment process has not ended (S33: NO), the communication distance restriction unit 24 waits until the payment process ends. When the settlement process is completed (S33: YES), the communication distance restriction unit 24 gives an instruction to return the signal strength to the original strength to the non-contact communication unit 16 (Step S34), and the process is terminated.

  Note that contactless communication between the portable information processing device 1 and the IC card 7 is performed a plurality of times in one settlement process, but the communication distance restriction unit 24 restricts the first contactless communication. It is good also as a structure which does not restrict | limit about the non-contact communication after the 2nd time. In addition to the method for reducing the strength of the radio signal output from the non-contact communication unit 16 as described above, the method for limiting the distance at which non-contact communication with the IC card 7 can be performed is, for example, Modification 6 below. It is also possible to adopt the method shown in FIG.

(Modification 6)
The non-contact communication unit 16 of the portable information processing device 1 according to the modification 6 has a function of measuring the signal strength of the radio signal when receiving the radio signal related to the non-contact communication from the IC card 7. Yes. When the wireless signal from the IC card 7 is received, the non-contact communication unit 16 gives the data related to the wireless signal to the processing unit 10 and notifies the processing unit 10 of the measured signal strength.

  The communication distance restriction unit 24 of the processing unit 10 determines whether the signal strength notified from the non-contact communication unit 16 exceeds a threshold value. When the signal strength does not exceed the threshold value, the communication distance restriction unit 24 invalidates the received signal and does not perform the settlement process based on the data from the IC card 7 included in the received signal. When the signal strength exceeds the threshold value, the communication distance restriction unit 24 validates the received signal and performs a settlement process.

  FIG. 19 is a flowchart illustrating a communication distance restriction process performed by the portable information processing device 1 according to the sixth modification. The non-contact communication unit 16 of the portable information processing apparatus 1 according to Modification 6 determines whether or not a wireless signal from the IC card 7 has been received (step S41). When the wireless signal is not received (S41: NO), the non-contact communication unit 16 waits until the wireless signal is received. When the wireless signal is received (S41: YES), the non-contact communication unit 16 measures the signal strength of the received wireless signal (step S42).

  The communication distance restriction unit 24 of the processing unit 10 of the portable information processing device 1 determines whether or not the signal intensity measured by the non-contact communication unit 16 exceeds a predetermined threshold (step S43). When the signal strength exceeds the threshold (S43: YES), the communication distance restriction unit 24 validates the signal received by the non-contact communication unit 16 (step S44), and the settlement process using the data included in the received signal (Step S45), and the process returns to step S41. When the signal strength does not exceed the threshold (S43: NO), the communication distance restriction unit 24 invalidates the signal received by the non-contact communication unit 16 (step S46), and performs the process to step S41 without performing the settlement process. return.

<Summary>
In the buying and selling system according to the present embodiment, the portable information processing device 1 or the stationary information processing device 2 and the server device 5 communicate with each other, and the settlement processing related to the product bought and sold via the sales server device 3 In this configuration, the card 7 is used. The portable information processing device 1 according to the present embodiment includes a non-contact communication unit 16 that performs non-contact communication with the IC card 7 and a function of preventing unauthorized data acquisition from the IC card 7. .

  The portable information processing apparatus 1 according to the present embodiment includes an attitude detection unit 17 that detects the attitude of the apparatus using an acceleration sensor, a gyro sensor, or the like. The posture restriction unit 22 of the portable information processing device 1 restricts the payment process when the posture detected by the posture detection unit 17 does not satisfy a predetermined posture condition. At this time, the posture restriction unit 22 restricts payment processing by restricting data acquisition from the IC card 7 by non-contact communication. As a result, since the attitude of the apparatus when performing the payment process using the IC card 7 can be restricted, a malicious user illegally uses the portable information processing apparatus 1 and uses the IC card of another user. 7 can be prevented from being used for own payment without permission.

  Further, after the non-contact communication with the IC card 7 is completed in the settlement process, for example, after the reduction process shown in FIG. 9 is completed, the portable information processing apparatus 1 settles based on the attitude detected by the attitude detection unit 17. Do not limit processing. By limiting the posture restriction when performing non-contact communication with the IC card 7, it is possible to suppress a reduction in convenience of the portable information processing apparatus 1 due to the posture restriction.

  Further, the display processing unit 25 of the portable information processing device 1 displays on the display unit 13 an image for prompting the posture of the own device to satisfy the posture condition, for example, a warning message display screen shown in FIG. The portable information processing device 1 displays a warning message display screen on the display unit 13 when the posture restriction unit 22 restricts the payment process. Accordingly, it is possible to notify the user that the portable information processing device 1 needs to satisfy the posture condition in order to perform the payment process.

  In addition, the posture restriction unit 22 of the portable information processing device 1 restricts the payment process on the basis of the posture condition that the own device is placed in a substantially horizontal plane. For example, the posture restriction unit 22 performs the settlement process with the posture condition that the surface of the casing of the portable information processing apparatus 1 that performs non-contact communication with the IC card 7 is substantially horizontal (within a range of horizontal ± 15 °). Make restrictions. As a result, the portable information processing device 1 cannot be used for payment processing in a substantially vertical posture, and therefore, unauthorized use of the portable information processing device 1 by a malicious user can be suppressed.

  In addition, the posture restriction unit 22 of the portable information processing device 1 may restrict the settlement process on the basis of the posture condition that the device is in a substantially stationary state. For example, the posture restriction unit 22 can set the posture condition in a substantially stationary state that the change in posture detected by the posture detection unit 17 does not exceed a threshold value. This makes it difficult to carry out payment processing while carrying the portable information processing apparatus 1, so that unauthorized use of the portable information processing apparatus 1 by a malicious user can be suppressed.

  The portable information processing apparatus 1 and the stationary information processing apparatus 2 may be configured to perform information processing related to a game by executing a game program. That is, the portable information processing device 1 and the stationary information processing device 2 may be a portable game device and a stationary game device. By installing a function for performing payment processing using the IC card 7 in the game device, the user can purchase a game program or an item in the game using the IC card 7. Can be improved.

  In addition, the IC card 7 may be shared with an IC card that can be used for fare payment of transportation such as a train or a bus. As a result, the user does not need to possess a dedicated IC card for payment of the online trading system, and the convenience of using the system can be improved.

  The portable information processing apparatus 1 and the stationary information processing apparatus 2 perform non-contact communication with the IC card 7 after the OK operation is performed on the warning message display screen illustrated in FIG. 11, for example. A waiting time is provided until the payment processing is interrupted when non-contact communication is not performed within this waiting time. In the trading system according to the present embodiment, the standby time is set to be different between the portable information processing device 1 and the stationary information processing device 2. For example, the standby time of the portable information processing device 1 is shorter than the standby time of the stationary information processing device 2. Further, the settlement server device 5 designates a standby time for the portable information processing device 1 and the stationary information processing device 2. However, in the present embodiment, a time shorter than the standby time specified by the settlement server device 5 is set as the standby time of the portable information processing device 1. Accordingly, unauthorized use of the portable information processing apparatus 1 can be suppressed, and the convenience of the stationary information processing apparatus 2 that is difficult to be illegally used can be prevented from being lowered.

  In addition, the portable information processing device 1 displays a screen for accepting input from the user on the display unit 13 before the stage of performing non-contact communication with the IC card 7 in the settlement processing, and accepts input on this screen. Later, the process proceeds to a stage where contactless communication is performed. Thereafter, when the payment process fails, the portable information processing device 1 returns the display to the input acceptance screen. The input acceptance screen can be, for example, the payment method selection screen shown in FIG. 10 or a screen for selecting a previous product. This makes it difficult to continuously attempt non-contact communication with the IC card 7, so that unauthorized use of the portable information processing apparatus 1 can be suppressed.

  In addition, the portable information processing device 1 acquires data from the IC card 7 and performs a settlement process when a state in which the contactless communication unit 16 can perform contactless communication with the IC card 7 is maintained for a predetermined time. I do. Accordingly, since it is necessary to keep the IC card 7 close to the portable information processing device 1 for a long time, unauthorized use of the portable information processing device 1 can be suppressed.

  Further, the settlement server device 5 stores settlement history information 51a in the storage unit 52, and the settlement history information 51a includes information related to whether or not the settlement process is correct. By storing such a history, it is possible to later search for information regarding a user who has attempted unauthorized use or the portable information processing device 1.

  Further, the portable information processing apparatus 1 performs wireless communication over a longer distance than the communication distance between the contactless communication unit 16 and the IC card 7 using the communication unit 15. The portable information processing device 1 performs communication with the server device 5 by wireless communication of the communication unit 15. Thereby, the convenience of the portable information processing apparatus 1 can be improved.

  In addition, the portable information processing device 1 limits the communication distance of non-contact communication when performing non-contact communication with the IC card 7 regarding the settlement process. For example, the communication distance restriction unit 24 of the portable information processing device 1 can shorten the communication distance of non-contact communication by reducing the strength of the radio signal output by the non-contact communication unit 16. Further, for example, the communication distance limiting unit 24 measures the intensity of the received signal from the IC card 7 and invalidates the received signal when the intensity does not exceed the threshold value, thereby shortening the communication distance of the non-contact communication. Can do. As a result, since it is necessary to bring the IC card 7 close to the portable information processing device 1 to a short distance during the settlement process, unauthorized use of the portable information processing device 1 can be suppressed.

  In the present embodiment, the sales server device 3 is configured as one device. However, the present invention is not limited to this, and the sales server device 3 may be configured by two or more devices. Similarly, in the present embodiment, the settlement server device 5 is configured as one device, but is not limited thereto, and the settlement server device 5 may be configured by two or more devices. Further, although the IC card 7 is used as a data storage medium for storing data related to settlement, the data storage medium is not limited to the card type and may be in various forms. For example, any communication device capable of non-contact communication may be used.

  Further, the processing procedures of the portable information processing device 1, the sales server device 3, and the settlement server device 5 shown in the present embodiment are merely examples, and the present invention is not limited to this. Moreover, the structure of the balance history information 73b shown in FIG. 4, the sales history information 31a shown in FIG. 6, and the settlement history information 51a shown in FIG. 8 is an example, and is not limited thereto. Further, the device configuration of the trading system and the sharing of functions in each device are not limited to those described in the present embodiment. For example, the sales server device 3 or the settlement server device 5 may have at least a part of what is described as the function of the portable information processing device 1 in the present embodiment. Conversely, the portable information processing device 1 may have at least a part of the functions described as the sales server device 3 or the settlement server device 5.

(Embodiment 2)
In the trading system according to the second embodiment, the settlement server device 5 controls the waiting time for the portable information processing device 1 and the stationary information processing device 2 to wait for non-contact communication with the IC card 7. is there. The portable information processing device 1 and the stationary information processing device 2 according to Embodiment 2 are preliminarily assigned with a device ID for identifying the device, and for example, the device ID is stored in the storage unit 11 or the like. . When the portable information processing device 1 and the stationary information processing device 2 transmit a payment request to the payment server device 5, the portable information processing device 1 and the stationary information processing device 2 transmit the device ID of their own device to the payment request.

  The device ID according to the present embodiment is information that can identify at least the type of device, for example, whether the device is a portable type or a stationary type. For this reason, the device ID does not have to be uniquely assigned to each device, and may be information common to a plurality of devices such as the model name or model number of the device.

  The payment server device 5 that has received the payment request from the portable information processing device 1 or the stationary information processing device 2 determines the standby time based on the device ID attached to the payment request. For example, the settlement server device 5 determines whether the settlement request is from a portable or stationary device based on the device ID. The settlement server device 5 designates a long time such as 60 seconds as the standby time when the other device of the settlement processing is a stationary type. On the other hand, when the counterpart device of the settlement process is a portable type, the settlement server device 5 designates a short time such as 30 seconds as the standby time.

  The settlement server device 5 according to the second embodiment stores information for determining the type of device based on the device ID, for example, in the storage unit 51. This information can be, for example, a table in which either a portable type or a stationary type is associated with the device ID and stored. Note that the portable information processing device 1 and the stationary information processing device 2 may transmit information indicating the type of the device itself instead of the device ID to the payment server device 5 together with the payment request. In this case, the settlement server device 5 does not need to store the above table and the like, and can determine the standby time according to the device type received together with the settlement request.

  The portable information processing device 1 and the stationary information processing device 2 wait for non-contact communication with the IC card 7 for the waiting time specified together with the read command. In the first embodiment, the portable information processing device 1 uses a shorter waiting time for the designation of the waiting time from the settlement server device 5. On the other hand, the portable information processing device 1 according to the second embodiment waits for non-contact communication with the IC card 7 using the standby time specified by the settlement server device 5.

  FIG. 20 is a flowchart illustrating a procedure of standby time control processing by the settlement server device 5 according to the second embodiment. The processing unit 50 of the payment server device 5 determines whether or not a payment request from the portable information processing device 1 or the stationary information processing device 2 has been received (step S51). When the settlement request has not been received (S51: NO), the processing unit 50 stands by until a settlement request is received. When the payment request is received (S51: YES), the processing unit 50 acquires the device ID included in the payment request (step S52).

  Based on the acquired device ID, the processing unit 50 refers to, for example, a table stored in the storage unit 51 to determine whether or not the device that transmitted the settlement request is portable (step S53). . When it determines with it being a portable type (S53: YES), the process part 50 designates short time, for example, 30 seconds as standby time (step S54), and complete | finishes a process. When it determines with it not being a portable type (S53: NO), the process part 50 designates long time, for example, 60 second, for example as a waiting time (step S55), and complete | finishes a process.

  The information transmitted from the portable information processing device 1 and the stationary information processing device 2 to the settlement server device 5 is not limited to the device ID, and may be various other information. As information other than the device ID, for example, information shown in the following modified examples 7 to 9 can be transmitted from the portable information processing device 1 and the stationary information processing device 2 to the settlement server device 5.

(Modification 7)
In the trading system according to the modified example 7, the portable information processing device 1 and the stationary information processing device 2 settle the information indicating the type of service using the IC card 7, that is, the type of service provided by the sales server device 3. It transmits to the server device 5. For example, the sales server device 3 stores the service ID assigned to the service in the storage unit 31. When the sales server device 3 provides a plurality of services, a plurality of service IDs may be given to one sales server device 3. When the sales server device 3 transmits a payment request to the payment server device 5 via the portable information processing device 1 or the stationary information processing device 2, the sales server device 3 reads the service ID from the storage unit 31 and attaches it to the payment request. Send. The portable information processing device 1 and the stationary information processing device 2 transmit the settlement request from the sales server device 3 to the settlement server device 5 together with the service ID included therein.

  The settlement server device 5 acquires the service ID included in the settlement request received from the portable information processing device 1 or the stationary information processing device 2, and determines the standby time based on the service ID. The payment server device 5 stores a table in which the service ID and the standby time are associated with each other in the storage unit 51, and determines the standby time by referring to the table based on the service ID acquired from the payment request.
