Description

情報コード表示装置及び情報コード読取システムInformation code display device and information code reading system
　本開示は、情報コードを表示する情報コード表示装置及び情報コード読取システムに関し、特に、商取引の際に端末によって読み取られる情報コードを表示する情報コード表示装置および情報コード読取システムに関する。 The present disclosure relates to an information code display device and an information code reading system for displaying an information code, and more particularly to an information code display device and an information code reading system for displaying an information code read by a terminal in a commercial transaction.
　近年、ＱＲコード（登録商標）等の情報コードを用いて決済を行う決済方式が多く採用されている。このような決済方式の１つとして、店舗側にて表示された情報コードを購入者の携帯端末にて読み取るユーザ読取型の決済方式（ＭＰＭ：Ｍｅｒｃｈａｎｔ－Ｐｒｅｓｅｎｔｅｄ　Ｍｏｄｅ）が提案されている。このようなユーザ読取型の決済方式では、店舗側は、情報コードを光学的に読み取る装置等を用意する必要が無く、購入者に読み取らせる情報コードを表示できればよいので、情報コードを用いた決済方式の導入に必要な店舗側の導入コストを低減できるというメリットがある。その一方で、紙媒体等に決済用の情報コードを印刷しただけでは、情報コードのすり替え等の不正行為に対して有効な対策を施すことが困難であり、セキュリティ的に問題がある。 In recent years, many payment methods have been adopted in which payments are made using information codes such as QR codes (registered trademarks). As one of such payment methods, a user-readable payment method (MPM: Merchant-Presented Mode) in which the information code displayed on the store side is read by the purchaser's mobile terminal has been proposed. In such a user-reading payment method, the store side does not need to prepare a device or the like that optically reads the information code, and only needs to be able to display the information code to be read by the purchaser. Therefore, payment using the information code is required. There is an advantage that the introduction cost on the store side required for introducing the method can be reduced. On the other hand, it is difficult to take effective measures against fraudulent acts such as replacement of information codes only by printing the information code for payment on a paper medium or the like, which poses a security problem.
　この問題を解決するため、例えば、下記特許文献１に開示される決済システムが知られている。この決済システムによる決済サービスでは、ユーザが店舗での買い物などの商取引を行う際、店舗が決済事業者から発行された識別コード（情報コード）をタブレット端末等の画面表示を利用してユーザに提示し、当該提示された識別コードをユーザが携帯端末で読み取って支払い額を指定することにより決済が完了する。 In order to solve this problem, for example, a payment system disclosed in Patent Document 1 below is known. In the payment service using this payment system, when a user conducts a commercial transaction such as shopping at a store, the store presents an identification code (information code) issued by the payment operator to the user using a screen display of a tablet terminal or the like. Then, the payment is completed when the user reads the presented identification code with the mobile terminal and specifies the payment amount.
特許６５２７２８２号公報Japanese Patent No. 6527282
　しかしながら、上記特許文献１のように、決済用の情報コードの表示装置としてタブレット端末等を採用する構成では、紙媒体等に決済用の情報コードを印刷する場合と比較して、そのタブレット端末等の製品価格が高い。また、情報コードを常時画面表示する必要があるために消費電力の低減も困難であり、導入コストおよび運用コストが高くなるという課題がある。 However, in the configuration in which the tablet terminal or the like is adopted as the display device of the information code for payment as in Patent Document 1, the tablet terminal or the like is compared with the case where the information code for payment is printed on a paper medium or the like. Product price is high. Further, since it is necessary to constantly display the information code on the screen, it is difficult to reduce the power consumption, and there is a problem that the introduction cost and the operation cost are high.
　本開示は、セキュリティ性を担保しつつ、導入コスト等を低減可能なユーザ読取型の決済方式用の情報コード表示装置及び情報コード読取システムに関する。 The present disclosure relates to an information code display device and an information code reading system for a user-reading type payment method that can reduce the introduction cost while ensuring security.
　本開示の第1の態様は、
　携帯端末（２０）に読み取らせる情報コード（Ｃ）を表示する情報コード表示装置（１０）であって、当該情報コード表示装置は、
　電子ペーパーを備えた表示部（１３）と、
　有効期間が設定された複数の情報コードが記憶される記憶部（１２）と、
　前記電子ペーパーの表示状態を制御する表示制御部（１１）と、
　前記表示制御部に電力を供給する電力供給用の電源部（１６）と、
　を備え、
　前記表示制御部は、前記電源部からの電力供給を受けることで、前記記憶部に記憶される前記複数の情報コードのうち有効期間内となる１つないし複数の情報コードを表示させるように前記電子ペーパーを制御することを特徴とする。
　なお、上記各括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示す。 The first aspect of the present disclosure is
An information code display device (10) that displays an information code (C) to be read by a mobile terminal (20), and the information code display device is
A display unit (13) equipped with electronic paper and
A storage unit (12) that stores a plurality of information codes for which a valid period is set, and
A display control unit (11) that controls the display state of the electronic paper, and
A power supply unit (16) for supplying electric power to the display control unit, and
With
By receiving the power supply from the power supply unit, the display control unit displays one or a plurality of information codes that are within the valid period among the plurality of information codes stored in the storage unit. It is characterized by controlling electronic paper.
The reference numerals in the parentheses indicate the correspondence with the specific means described in the embodiments described later.
　本開示の第１の態様では、表示制御部は、電源部からの電力供給を受けることで、記憶部に記憶される複数の情報コードのうち有効期間内となる１つないし複数の情報コードを表示させるように電子ペーパーを制御する。 In the first aspect of the present disclosure, the display control unit receives power from the power supply unit to obtain one or more information codes within the valid period among the plurality of information codes stored in the storage unit. Control the electronic paper to display.
　これにより、電子ペーパーには有効期間内となる情報コードが順に切り替わるように表示されるため、紙媒体に印刷された情報コードよりもセキュリティ性を高めることができる。さらに、情報コードを画面表示する表示媒体として電子ペーパーを採用するため、多機能型のタブレット端末等を上記情報コード表示装置として採用する場合と比較して、製品価格が安くなるので、導入コストを低減することができる。特に、電子ペーパーは、電力供給されなくても表示状態が維持されるため、情報コードの有効期間が比較的長い場合には、電源部からの電力供給を受けることなく情報コードの表示状態を維持できるので、多機能型のタブレット端末等と比較して、消費電力の低減を図ることができる。したがって、セキュリティ性を担保しつつ、導入コストや運用コスト等を低減可能なユーザ読取型の決済方式用の情報コード表示装置を実現することができる。 As a result, the information code within the valid period is displayed on the electronic paper so as to be switched in order, so that the security can be improved as compared with the information code printed on the paper medium. Furthermore, since electronic paper is used as the display medium for displaying the information code on the screen, the product price is lower than when a multifunctional tablet terminal or the like is used as the information code display device, so that the introduction cost is reduced. It can be reduced. In particular, since the display state of electronic paper is maintained even if power is not supplied, when the validity period of the information code is relatively long, the display state of the information code is maintained without receiving power supply from the power supply unit. Therefore, it is possible to reduce power consumption as compared with a multifunctional tablet terminal or the like. Therefore, it is possible to realize an information code display device for a user-readable payment method that can reduce the introduction cost, the operation cost, and the like while ensuring the security.
　本開示の第２の態様では、電源部が電力供給停止状態から電力供給可能状態に切り替わった際に、判定部により電子ペーパーに表示される情報コードが有効期間内でないと判定されると、有効期間内の他の情報コードを表示させるように電子ペーパーが表示制御部により制御される。 In the second aspect of the present disclosure, when the power supply unit is switched from the power supply stop state to the power supply available state, it is valid if the determination unit determines that the information code displayed on the electronic paper is not within the valid period. The electronic paper is controlled by the display control unit so as to display other information codes within the period.
　これにより、電力供給停止状態であるために有効期間外の情報コードが電子ペーパーに表示されていても、電力供給可能状態に切り替えるだけで、電子ペーパーに表示される情報コードが有効期間外のものから有効期間内のものに切り替えられる。このため、電子ペーパーに表示される情報コードを光学的に読み取った携帯端末等にて有効期間外であると通知されてから電力供給可能状態に切り替えればよく、上記携帯端末等にて有効期間外であると通知されるまで電力供給停止状態であっても問題は生じないので、この点からも消費電力の低減を図ることができる。 As a result, even if the information code outside the valid period is displayed on the electronic paper because the power supply is stopped, the information code displayed on the electronic paper is outside the valid period simply by switching to the power supply enabled state. Can be switched from to the one within the valid period. Therefore, it suffices to switch to the power supplyable state after being notified that the information code displayed on the electronic paper is out of the valid period by the mobile terminal or the like optically read, and the mobile terminal or the like is out of the valid period. Since no problem occurs even if the power supply is stopped until the notification is made, the power consumption can be reduced from this point as well.
　本開示の第３の態様では、情報コード表示装置に表示された情報コードを光学的に読み取る携帯端末には、有効期間外の情報コードが読み取られた際に、その旨を報知する報知部が設けられる。このため、上記報知を受けた携帯端末のユーザは、情報コード表示装置に有効期間外の情報コードが表示されることを容易に把握することができる。 In the third aspect of the present disclosure, the mobile terminal that optically reads the information code displayed on the information code display device has a notification unit that notifies the fact when the information code outside the valid period is read. Provided. Therefore, the user of the mobile terminal who has received the above notification can easily grasp that the information code outside the valid period is displayed on the information code display device.
　本開示の第４の態様では、報知部は、有効期間外の情報コードが読み取られた際に、電力供給可能状態への切り替えを促す情報を報知する。このため、その報知を受けた情報コード表示装置の管理者（例えば、店員等）が情報コード表示装置を電力供給可能状態に切り替えることで、電子ペーパーに表示される情報コードが有効期間外のものから有効期間内のものに切り替えられるので、有効期間外の情報コードが読み取られてしまうという問題を早期に解消することができる。 In the fourth aspect of the present disclosure, the notification unit notifies information prompting the switch to the power supply available state when the information code outside the valid period is read. Therefore, when the manager of the information code display device (for example, a clerk) who receives the notification switches the information code display device to the power supplyable state, the information code displayed on the electronic paper is out of the valid period. Since it is possible to switch from to the one within the valid period, the problem that the information code outside the valid period is read can be solved at an early stage.

［第１実施形態］
　以下、本開示の情報コード表示装置及び情報コード読取システムを具現化した第１実施形態について、図１を参照して説明する。
　図１に示されている本実施形態に係る情報コード読取システム１は、情報コードＣを利用したユーザ読取型の決済方式（ＭＰＭ方式）を採用する決済システムとして構成されており、情報コードＣを表示する情報コード表示装置１０と、この情報コードＣを光学的に読み取る携帯端末２０と、を備えている。 [First Embodiment]
Hereinafter, the first embodiment embodying the information code display device and the information code reading system of the present disclosure will be described with reference to FIG.
The information code reading system 1 according to the present embodiment shown in FIG. 1 is configured as a payment system that employs a user reading type payment method (MPM method) using the information code C, and the information code C is used. It includes an information code display device 10 for displaying and a mobile terminal 20 for optically reading the information code C.
　情報コード読取システム１は、例えば、店舗内に設置されたＰＯＳレジスタ２での決済処理に利用される。例えば、情報コード表示装置１０は、ＰＯＳレジスタ２の近傍に配置されている。携帯端末２０は、例えば、購入者が決済用に利用するスマートフォン等である。購入者は、商品を購入する際に、携帯端末２０にて所定の決済アプリを起動し、情報コード表示装置１０に画面表示される情報コードＣを携帯端末２０にて光学的に読み取った後に、購入金額等の入力操作を行う。これにより、携帯端末２０では、情報コードＣの読取結果や購入金額、購入者を特定する個人情報等を決済サーバ３０に送信する。決済サーバ３０は携帯端末２０からの受信に応じて、携帯端末２０に決済情報等を送信する。携帯端末２０には、決済サーバ３０から受信した決済情報等が画面表示される。この携帯端末２０に画面表示された決済情報等を、ＰＯＳレジスタ２を操作する店員等に見せることで決済が完了する。このため、情報コード表示装置１０に表示される情報コードＣには、少なくとも、店舗等及びＰＯＳレジスタ２を特定可能な情報（以下、単に、店舗情報ともいう）が記録される。なお、本実施形態では、決済用の情報コードＣとして、ＱＲコードが採用されているが、これに限らず、バーコード等の一次元コードやデータマトリックスコード、マキシコード等の二次元コードなどの他のコード種別の情報コードが情報コード表示装置１０に表示される情報コードＣとして採用されてもよい。 The information code reading system 1 is used, for example, for payment processing at the POS register 2 installed in the store. For example, the information code display device 10 is arranged in the vicinity of the POS register 2. The mobile terminal 20 is, for example, a smartphone or the like used by the purchaser for payment. When purchasing a product, the purchaser activates a predetermined payment application on the mobile terminal 20, optically reads the information code C displayed on the screen on the information code display device 10 on the mobile terminal 20, and then optically reads the information code C. Enter the purchase price, etc. As a result, the mobile terminal 20 transmits the reading result of the information code C, the purchase price, personal information that identifies the purchaser, and the like to the payment server 30. The payment server 30 transmits payment information and the like to the mobile terminal 20 in response to the reception from the mobile terminal 20. The mobile terminal 20 displays the payment information and the like received from the payment server 30 on the screen. The payment is completed by showing the payment information or the like displayed on the screen of the mobile terminal 20 to the clerk or the like who operates the POS register 2. Therefore, at least information that can identify the store or the like and the POS register 2 (hereinafter, also simply referred to as store information) is recorded in the information code C displayed on the information code display device 10. In the present embodiment, a QR code is adopted as the information code C for payment, but the present invention is not limited to this, and one-dimensional codes such as barcodes, data matrix codes, two-dimensional codes such as maxi codes, etc. An information code of another code type may be adopted as the information code C displayed on the information code display device 10.
　次に、本実施形態に係る情報コード表示装置１０の構成について、図面などを参照して詳述する。
　本実施形態に係る情報コード表示装置１０は、セキュリティ性を担保しつつ、導入コストを低減するため、情報コードＣを画面表示する表示部（表示媒体）として電子ペーパー１３が採用されている。なお、本実施形態では、電子ペーパー１３が表示部に相当する構成を採用しているが、表示部自体は、電子ペーパー１３に、表示に係る他の要素を付加された構成を採用してもよい。
　なお、電子ペーパー１３が採用されている理由は、多機能型のタブレット端末等と比較して低コストで製造できるだけでなく、電力供給停止後も表示を維持することができる表示保持性を有することから運用コストの低減も容易であるため、導入コストの低減を容易に図ることができるからである。 Next, the configuration of the information code display device 10 according to the present embodiment will be described in detail with reference to drawings and the like.
In the information code display device 10 according to the present embodiment, electronic paper 13 is adopted as a display unit (display medium) for displaying the information code C on the screen in order to reduce the introduction cost while ensuring the security. In the present embodiment, the electronic paper 13 adopts a configuration corresponding to the display unit, but the display unit itself may adopt a configuration in which other elements related to the display are added to the electronic paper 13. Good.
The reason why the electronic paper 13 is adopted is that it can be manufactured at a lower cost than a multifunctional tablet terminal or the like, and has a display retention property that can maintain the display even after the power supply is stopped. Therefore, it is easy to reduce the operating cost, so that the introduction cost can be easily reduced.
　このため、図２に示すように、情報コード表示装置１０は、上記電子ペーパー１３に加えて、全体制御を司る制御部１１や記憶部１２、操作部１４、外部インタフェース１５、電力供給用の電源部１６を備えるように構成されている。制御部１１は、演算を担うＣＰＵ（central　processing　unit）１１Ａ、システムバス、入出力インタフェース１１Ｂ等からなるもので、記憶部１２とともに情報処理装置を構成している。ＣＰＵ１１Ａは、コンピュータシステムの中枢を担う要素であって、同様の機能を保有するものであれば、呼び名は違っていても（例えば、プロセッサ、演算装置）よいことは勿論である。記憶部１２は、例えば、ＲＯＭ（read-only　memory）１２Ａ、ＲＡＭ（random-access　memory）を含む半導体メモリ装置であって、個々に有効期間が設定された複数の情報コードＣや、情報コードＣを電子ペーパー１３の表示画面に表示するために制御部１１にて情報コード表示処理を行うためのアプリケーションプログラム等の手順がソースコードとして、読み出し可能に記憶されている。制御部１１に備えられているＣＰＵ１１Ａは、記憶部１２に記憶された当該情報コード表示処理を行うためのアプリケーションプログラムを実行することにより、制御部１１全体を所定の情報コード表示処理が実行されるように制御する。なお、制御部１１（すなわち、ＣＰＵ１１Ａ）によって実行される情報コード表示処理については後述する。記憶部１２にうち、例えば、ＲＯＭ１２Ａは、非一過性記録媒体（non-transitory　computer　readable　recording　medium）を構成し、後述する決済処理を記述したソースコードが事前に記録されている。 Therefore, as shown in FIG. 2, in addition to the electronic paper 13, the information code display device 10 includes a control unit 11, a storage unit 12, an operation unit 14, an external interface 15, and a power supply for power supply, which control overall control. It is configured to include a portion 16. The control unit 11 is composed of a CPU (central processing unit) 11A, a system bus, an input / output interface 11B, etc., which is responsible for calculation, and constitutes an information processing device together with a storage unit 12. It goes without saying that the CPU 11A may have a different name (for example, a processor, an arithmetic unit) as long as it is an element that plays a central role in a computer system and has the same functions. The storage unit 12 is, for example, a semiconductor memory device including a ROM (read-only memory) 12A and a RAM (random-access memory), and a plurality of information codes C and information codes C for which validity periods are individually set. The procedure of the application program or the like for performing the information code display processing in the control unit 11 in order to display the information on the display screen of the electronic paper 13 is readable and stored as the source code. The CPU 11A provided in the control unit 11 executes a predetermined information code display process for the entire control unit 11 by executing an application program for performing the information code display process stored in the storage unit 12. To control. The information code display process executed by the control unit 11 (that is, the CPU 11A) will be described later. Among the storage units 12, for example, the ROM 12A constitutes a non-transitory computer readable recording medium, and a source code describing a payment process described later is recorded in advance.
　電子ペーパー１３は、例えば、電気泳動方式または電子粉粒体方式によって所定の情報を表示し、制御部１１によりその表示状態が制御されるように構成されている。 The electronic paper 13 is configured to display predetermined information by, for example, an electrophoresis method or an electronic powder or granular material method, and the display state is controlled by the control unit 11.
　操作部１４は、筐体の側面等に設けられる複数のキー１４Ａを備え、キー操作に応じた操作信号を制御部１１に出力するように構成されている。外部インタフェース１５は、上位機器等の外部装置との間でのデータ通信を行うためのインタフェースとして構成されており、制御部１１と協働して通信処理を行うように構成されている。電源部１６は、コンセントに接続された電源ケーブル（図示略）を介して供給される電力を、制御部１１、記憶部１２、および電子ペーパー１３等に供給するように構成されている。 The operation unit 14 includes a plurality of keys 14A provided on the side surface of the housing or the like, and is configured to output an operation signal corresponding to the key operation to the control unit 11. The external interface 15 is configured as an interface for performing data communication with an external device such as a host device, and is configured to perform communication processing in cooperation with the control unit 11. The power supply unit 16 is configured to supply electric power supplied via a power cable (not shown) connected to an outlet to the control unit 11, the storage unit 12, the electronic paper 13, and the like.
　このように構成される情報コード表示装置１０では、電源部１６により電力が供給される電力供給可能状態時には、有効期間内となる情報コードＣを電子ペーパー１３の表示画面に表示するために、制御部１１にて情報コード表示処理がなされる。情報コード表示処理では、記憶部１２に記憶される複数の情報コードＣのうち有効期間内となる１つないし複数の情報コードＣが電子ペーパー１３の表示画面に表示される。 In the information code display device 10 configured in this way, when power is supplied by the power supply unit 16 and the power supply is possible, the information code C within the valid period is controlled in order to be displayed on the display screen of the electronic paper 13. Information code display processing is performed in unit 11. In the information code display process, one or a plurality of information codes C within the valid period among the plurality of information codes C stored in the storage unit 12 are displayed on the display screen of the electronic paper 13.
　より具体的には、情報コード表示処理では、処理開始時、すなわち、電源部１６が制御部１１、記憶部１２、および電子ペーパー１３等への電力供給を行わない電力供給停止状態から制御部１１等に電力を供給する電力供給可能状態に切り替わった際に、既に電子ペーパー１３の表示画面に情報コードＣが表示されていると、表示されている情報コードＣが有効期間内であるか否か制御部１１が判定し、有効期間内であると判定した場合、情報コードＣの表示状態が維持される。すなわち、制御部１１は、有効期間内であると判定した場合電子ペーパー１３に電力を供給しないため、電子ペーパー１３に既に表示されている情報コードＣが継続して表示される。一方、制御部１１は有効期間外であると判定した場合、有効期間内となる別の情報コードＣを表示するように、電子ペーパー１３の表示状態が制御される。制御部１１は有効期間外であると判定した場合、例えば、電子ペーパー１３に電力を供給することにより、電子ペーパー１３に表示されている有効期間外である判定した情報コードＣの替わりに、有効期間内となる別の情報コードＣを電子ペーパー１３に表示させる。制御部１１は、その後も、継続して、表示されている情報コードＣが有効期間内であるか否かについて判定し、有効期間外であると判定した場合、有効期間内となる別の情報コードＣを表示するように、電子ペーパー１３の表示状態が制御される。このため、情報コードＣは、上記店舗情報に加えて、有効期間に関する情報が記録されるように生成されて、その有効期間に関連付けられるように記憶部１２に記憶される。なお、電子ペーパー１３の表示画面には、１つの情報コードＣが表示されることに限らず、有効期間内となる複数の情報コードＣが表示されてもよい。また、制御部１１は、有効期間内となる情報コードＣを電子ペーパー１３に表示させた後、電子ペーパー１３への電力供給を停止するように構成されてもよい。この場合、電子ペーパー１３への電力供給を継続しないため、情報コードＣを電子ペーパーにする際に消費される電力を抑制することができる。 More specifically, in the information code display process, the control unit 11 starts processing, that is, from a power supply stop state in which the power supply unit 16 does not supply power to the control unit 11, the storage unit 12, the electronic paper 13, and the like. If the information code C is already displayed on the display screen of the electronic paper 13 when the state is switched to the power supply available state for supplying power to the electronic paper 13, whether or not the displayed information code C is within the valid period. When the control unit 11 determines and determines that the period is within the valid period, the display state of the information code C is maintained. That is, since the control unit 11 does not supply electric power to the electronic paper 13 when it is determined that the period is within the valid period, the information code C already displayed on the electronic paper 13 is continuously displayed. On the other hand, when the control unit 11 determines that it is out of the valid period, the display state of the electronic paper 13 is controlled so as to display another information code C within the valid period. When the control unit 11 determines that the validity period is out of the valid period, for example, by supplying electric power to the electronic paper 13, the control unit 11 is effective instead of the information code C determined to be out of the valid period displayed on the electronic paper 13. Another information code C within the period is displayed on the electronic paper 13. After that, the control unit 11 continuously determines whether or not the displayed information code C is within the valid period, and if it is determined that the displayed information code C is outside the valid period, another information that is within the valid period. The display state of the electronic paper 13 is controlled so as to display the code C. Therefore, the information code C is generated so as to record information on the validity period in addition to the store information, and is stored in the storage unit 12 so as to be associated with the validity period. The display screen of the electronic paper 13 is not limited to displaying one information code C, and a plurality of information codes C within the valid period may be displayed. Further, the control unit 11 may be configured to stop the power supply to the electronic paper 13 after displaying the information code C within the valid period on the electronic paper 13. In this case, since the power supply to the electronic paper 13 is not continued, the power consumed when the information code C is made into the electronic paper can be suppressed.
　これにより、コンセントから電源ケーブルが取り外されたために電源部１６が電力供給停止状態となっても、電力供給停止状態になった直後であれば、有効期間内の情報コードＣが電子ペーパー１３に画面表示された状態が維持される。そして、この電力供給停止状態が継続したために画面表示されている情報コードＣが有効期間外となっても、電源ケーブルをコンセントに接続して電源部１６が電力供給可能状態になることで、有効期間内となる別の情報コードＣが画面表示されるように電子ペーパー１３の表示状態を切り替えることができる。 As a result, even if the power supply unit 16 is in the power supply stop state because the power cable is removed from the outlet, the information code C within the valid period is displayed on the electronic paper 13 immediately after the power supply stop state. The displayed state is maintained. Then, even if the information code C displayed on the screen is out of the valid period because the power supply stop state continues, it is effective by connecting the power cable to the outlet and making the power supply unit 16 in the power supply ready state. The display state of the electronic paper 13 can be switched so that another information code C within the period is displayed on the screen.
　なお、上記情報コード表示処理を行う制御部１１は、電子ペーパー１３の表示状態を制御する「表示制御部」の一例に相当する。また、制御部１１は、電源部１６が電力供給停止状態から電力供給可能状態に切り替わった際に、電子ペーパー１３に表示される情報コードＣが有効期間内であるか否かについて判定する「判定部」の一例に相当する。なお、情報コードＣは、予め上記店舗情報に加えて有効期間に関する情報が記録されるように生成されて記憶部１２に記憶されてもよいし、所定のタイミングで制御部１１にてなされる情報コード生成処理により上記店舗情報に加えて有効期間に関する情報が記録されるように都度生成されて記憶部１２に記憶されてもよい。また、記憶部１２に記憶される各情報コードＣは、所定のタイミング（例えば、電力供給可能状態に切り替わった直後）で、外部インタフェース１５を介して上位機器等から受信されることで更新されてもよい。 The control unit 11 that performs the information code display process corresponds to an example of a "display control unit" that controls the display state of the electronic paper 13. Further, the control unit 11 determines whether or not the information code C displayed on the electronic paper 13 is within the valid period when the power supply unit 16 switches from the power supply stop state to the power supply enable state. Corresponds to an example of "part". The information code C may be generated in advance so that information on the validity period is recorded in addition to the store information and stored in the storage unit 12, or information is provided by the control unit 11 at a predetermined timing. It may be generated each time by the code generation process so that the information regarding the validity period is recorded in addition to the store information and stored in the storage unit 12. Further, each information code C stored in the storage unit 12 is updated by being received from a higher-level device or the like via the external interface 15 at a predetermined timing (for example, immediately after switching to the power supply available state). May be good.
　次に、本実施形態に係る携帯端末２０の構成について、図面などを参照して詳述する。
　本実施形態に係る携帯端末２０は、例えば、上記決済アプリ等がインストールされたスマートフォン等であって、図３に示すように、演算を担うＣＰＵ（central　processing　unit）２１Ａおよび入出力インタフェース２１Ｂ等からなる制御部２１、ＲＯＭ（read-only　memory）２２ＡおよびＲＡＭ（random-access　memory）２２Ｂ等を備え、上記個人情報およびソースコードとして情報コードＣを利用した決済処理を実行するためのアプリケーションプログラム等が読み出し可能に記憶される記憶部２２、カメラとして構成される撮像部２３、制御部２１によって表示内容が制御されるタッチパネル式の表示部２４、タッチパネルに対するタッチ操作やキー操作に応じた操作信号を制御部２１に出力する操作部２５、決済サーバ３０等の外部機器と通信するための通信部２６などを備えている。制御部２１に備えられているＣＰＵ２１Ａは、記憶部２２に記憶された決済処理を行うためのアプリケーションプログラムを実行することにより、制御部２１全体を所定の決済処理が実行されるように制御する。なお、制御部２１（すなわち、ＣＰＵ２１Ａ）によって実行される決済処理については後述する。 Next, the configuration of the mobile terminal 20 according to the present embodiment will be described in detail with reference to drawings and the like.
The mobile terminal 20 according to the present embodiment is, for example, a smartphone or the like on which the payment application or the like is installed, and as shown in FIG. 3, from a CPU (central processing unit) 21A and an input / output interface 21B or the like that perform calculations. A control unit 21, a ROM (read-only memory) 22A, a RAM (random-access memory) 22B, and the like, and an application program and the like for executing payment processing using the information code C as the personal information and source code. A storage unit 22 that is readable and stored, an image pickup unit 23 that is configured as a camera, a touch panel type display unit 24 whose display contents are controlled by a control unit 21, and an operation signal corresponding to a touch operation or key operation on the touch panel are controlled. It includes an operation unit 25 that outputs to the unit 21, a communication unit 26 for communicating with an external device such as a payment server 30, and the like. The CPU 21A provided in the control unit 21 controls the entire control unit 21 so that a predetermined payment process is executed by executing an application program for performing the payment process stored in the storage unit 22. The settlement process executed by the control unit 21 (that is, the CPU 21A) will be described later.
　このように構成される携帯端末２０では、上記決済アプリを起動することで制御部２１にてなされる決済処理により、情報コード表示装置１０の電子ペーパー１３に表示された情報コードＣを読み取ることで、購入商品の決済が行われる。 In the mobile terminal 20 configured in this way, the information code C displayed on the electronic paper 13 of the information code display device 10 is read by the payment process performed by the control unit 21 by activating the payment application. , Purchased items are settled.
　以下、携帯端末２０において、制御部２１のＣＰＵ２１Ａにてなされる決済処理について、図４に示すフローチャートを参照して詳述する。
　上記決済アプリを起動することで決済処理が開始されると、ステップＳ１０１に示す読取処理がなされ、撮像状態になった撮像部２３により撮像された情報コードＣを解読（デコード）するための処理がなされる。情報コードの解読が成功すると、ステップＳ１０３に示す購入金額取得処理がなされ、タッチパネルを利用した操作部２５に対する購入金額の入力操作に応じて購入金額が取得される。 Hereinafter, the payment process performed by the CPU 21A of the control unit 21 in the mobile terminal 20 will be described in detail with reference to the flowchart shown in FIG.
When the payment process is started by starting the payment application, the reading process shown in step S101 is performed, and the process for decoding the information code C imaged by the imaging unit 23 in the imaging state is performed. Be done. When the information code is successfully decoded, the purchase amount acquisition process shown in step S103 is performed, and the purchase amount is acquired according to the input operation of the purchase amount to the operation unit 25 using the touch panel.
　購入金額の入力が完了すると、ステップＳ１０５に示す送信処理がなされ、情報コードＣの読取結果や購入金額、個人情報等が通信部２６を介して決済サーバ３０に送信される。 When the input of the purchase amount is completed, the transmission process shown in step S105 is performed, and the reading result of the information code C, the purchase amount, personal information, etc. are transmitted to the payment server 30 via the communication unit 26.
　決済サーバ３０では、携帯端末２０から受信した読取結果に上記店舗情報及び有効期間に関する情報が含まれており、この受信した有効期間が満了しておらず有効期間内であるか否かを判断し、有効期間内であると判断した場合には、正規の情報コードＣを読み取っているとして、受信した購入金額及び個人情報等を利用した決済処理を行う。そして、決済完了通知が携帯端末２０に対して送信される。一方、携帯端末２０から受信した読取結果に上記店舗情報及び有効期間に関する情報が含まれていても、この受信した有効期間が満了しており有効期間内でないと判断した場合には、有効期間外の情報コードＣを読み取っているとして、決済処理を行うことなく、有効期間外通知が携帯端末２０に対して送信される。また、携帯端末２０から受信した読取結果に上記店舗情報及び有効期間関連情報が含まれていないと判断した場合には、決済に利用できない情報コードを読み取っているとして、決済処理を行うことなく、決済無効通知が携帯端末２０に対して送信される。 The payment server 30 includes the above-mentioned store information and information on the validity period in the reading result received from the mobile terminal 20, and determines whether or not the received validity period has not expired and is within the validity period. If it is determined that the information is within the valid period, it is assumed that the legitimate information code C is being read, and payment processing is performed using the received purchase amount and personal information. Then, the payment completion notification is transmitted to the mobile terminal 20. On the other hand, even if the reading result received from the mobile terminal 20 includes the above-mentioned store information and information on the validity period, if it is determined that the received validity period has expired and is not within the validity period, it is out of the validity period. Assuming that the information code C is being read, the out-of-validity notification is transmitted to the mobile terminal 20 without performing payment processing. Further, when it is determined that the reading result received from the mobile terminal 20 does not include the store information and the validity period related information, it is assumed that the information code that cannot be used for payment is being read, and the payment process is not performed. A payment invalidation notification is transmitted to the mobile terminal 20.
　このため、携帯端末２０では、上記送信に応じて決済サーバ３０から決済完了通知が受信されると（Ｓ１０７でＹｅｓ）、ステップＳ１１３に示す決済有効表示処理がなされ、決済処理が完了した旨が表示部２４に画面表示されて報知される。購入者は、この表示を店員等に見せることで、商品購入が完了する。 Therefore, when the mobile terminal 20 receives the payment completion notification from the payment server 30 in response to the above transmission (Yes in S107), the payment valid display process shown in step S113 is performed, and it is displayed that the payment process is completed. The screen is displayed on the unit 24 to notify the user. The purchaser completes the product purchase by showing this display to the clerk or the like.
　一方、携帯端末２０では、上記送信に応じて決済サーバ３０から有効期間外通知が受信されると（Ｓ１０７でＮｏ，Ｓ１０９でＹｅｓ）、ステップＳ１１５に示す有効期間外表示処理がなされる。情報コード表示装置１０において、コンセントから電源ケーブルを取り外しているために電力供給停止状態が継続していることから、情報コードＣが更新されずに有効期間外になっていると、上述のように決済サーバ３０から有効期間外通知が受信されることとなる。 On the other hand, when the mobile terminal 20 receives the out-of-validity notification from the payment server 30 in response to the above transmission (No in S107, Yes in S109), the out-of-validity display process shown in step S115 is performed. In the information code display device 10, since the power supply stop state continues because the power cable is removed from the outlet, if the information code C is not updated and is out of the valid period, as described above. The out-of-validity notification will be received from the payment server 30.
　上記有効期間外表示処理では、例えば、図５（Ａ）に例示するように、情報コード表示装置１０に表示されている情報コードＣの有効期間が満了しており、店員等に対して情報コードＣの表示の更新を促す情報等が、携帯端末２０の表示部２４に画面表示されて報知される。店員等は、購入者が提示する携帯端末２０の画面表示を見ることで、情報コードＣの有効期間が満了していることを認識するため、電源ケーブルをコンセントに接続することで、電源部１６が電力供給可能状態になり有効期間内となる別の情報コードＣが画面表示されるように電子ペーパー１３の表示状態が制御部１１により切り替えられる。これにより、情報コード表示装置１０に表示される情報コードＣが有効に更新されるため、この情報コードＣを携帯端末２０にて読み取ることで、決済サーバ３０から決済完了通知が受信されて（Ｓ１０７でＹｅｓ）、決済処理が完了した旨が表示部２４に表示されることとなる。 In the non-valid period display process, for example, as illustrated in FIG. 5A, the valid period of the information code C displayed on the information code display device 10 has expired, and the information code is given to the clerk or the like. Information or the like prompting the update of the display of C is displayed on the screen of the display unit 24 of the mobile terminal 20 and notified. By looking at the screen display of the mobile terminal 20 presented by the purchaser, the clerk or the like recognizes that the validity period of the information code C has expired. Therefore, by connecting the power cable to the outlet, the power supply unit 16 The display state of the electronic paper 13 is switched by the control unit 11 so that another information code C, which is in the power supplyable state and is within the valid period, is displayed on the screen. As a result, the information code C displayed on the information code display device 10 is effectively updated. Therefore, by reading this information code C with the mobile terminal 20, a payment completion notification is received from the payment server 30 (S107). Yes), the fact that the payment process has been completed will be displayed on the display unit 24.
　また、携帯端末２０では、上記送信に応じて決済サーバ３０から決済無効通知が受信される場合（Ｓ１０７でＮｏ，Ｓ１０９でＮｏ）、ステップＳ１１７に示す決済無効表示処理がなされる。 Further, in the mobile terminal 20, when the payment invalidation notification is received from the payment server 30 in response to the above transmission (No in S107, No in S109), the payment invalidation display process shown in step S117 is performed.
　ステップＳ１１７に示す決済無効表示処理では、例えば、図５（Ｂ）に例示するように、情報コード表示装置１０に表示されている情報コードが有効なものではないことを示す情報等が表示部２４に画面表示される。店員等は、購入者が提示する携帯端末２０の画面表示を見ることで、購入者が決済用の情報コードＣと異なる他の情報コードを読み取っていることを認識する。このような場合には、店員等は、情報コード表示装置１０の表示状態等を確認することで、上記他の情報コードが読み取られる要因を把握してその除去を図ることができる。 In the payment invalidation display process shown in step S117, for example, as illustrated in FIG. 5B, information or the like indicating that the information code displayed on the information code display device 10 is not valid is displayed on the display unit 24. Is displayed on the screen. By looking at the screen display of the mobile terminal 20 presented by the purchaser, the clerk or the like recognizes that the purchaser is reading another information code different from the information code C for payment. In such a case, the store clerk or the like can grasp the cause of reading the other information code and try to eliminate it by checking the display state of the information code display device 10.
　以上説明したように、本実施形態に係る情報コード表示装置１０では、制御部１１は、電源部１６からの電力供給を受けることで、記憶部１２に記憶される複数の情報コードＣのうち有効期間内となる１つないし複数の情報コードＣを表示させるように電子ペーパー１３を制御する。 As described above, in the information code display device 10 according to the present embodiment, the control unit 11 is effective among the plurality of information codes C stored in the storage unit 12 by receiving the power supply from the power supply unit 16. The electronic paper 13 is controlled so as to display one or more information codes C within the period.
　これにより、電子ペーパー１３には有効期間内となる情報コードＣが順に切り替わるように表示されるため、紙媒体に印刷された情報コードよりもセキュリティ性を高めることができる。さらに、情報コードＣを画面表示する表示媒体として電子ペーパー１３を採用するため、多機能型のタブレット端末等を上記情報コード表示装置として採用する場合と比較して、製品価格が安くなるので、導入コストを低減することができる。特に、電子ペーパー１３は、電力供給されなくても表示状態が維持されるため、情報コードＣの有効期間が比較的長い場合には、電源部１６からの電力供給を受けることなく情報コードＣの表示状態を維持できるので、多機能型のタブレット端末等と比較して、消費電力の低減を図ることができる。したがって、セキュリティ性を担保しつつ、導入コストや運用コスト等を低減可能なユーザ読取型の決済方式用の情報コード表示装置１０を実現することができる。 As a result, the information code C within the valid period is displayed on the electronic paper 13 so as to be switched in order, so that the security can be improved as compared with the information code printed on the paper medium. Further, since the electronic paper 13 is adopted as the display medium for displaying the information code C on the screen, the product price is lower than the case where the multifunctional tablet terminal or the like is adopted as the information code display device. The cost can be reduced. In particular, since the electronic paper 13 maintains its display state even when power is not supplied, when the valid period of the information code C is relatively long, the information code C does not receive power from the power supply unit 16. Since the display state can be maintained, power consumption can be reduced as compared with a multifunctional tablet terminal or the like. Therefore, it is possible to realize the information code display device 10 for a user-readable payment method that can reduce the introduction cost, the operation cost, and the like while ensuring the security.
　特に、制御部１１にてなされる情報コード表示処理では、電源部１６が電力供給停止状態から電力供給可能状態に切り替わった際に、電子ペーパー１３に表示される情報コードＣが有効期間内でないと判定されると、有効期間内の他の情報コードＣを表示させるように電子ペーパー１３が制御される。 In particular, in the information code display process performed by the control unit 11, when the power supply unit 16 switches from the power supply stop state to the power supply enable state, the information code C displayed on the electronic paper 13 must be within the valid period. If determined, the electronic paper 13 is controlled to display another information code C within the valid period.
　これにより、電力供給停止状態であるために有効期間外の情報コードＣが電子ペーパー１３に表示されていても、電力供給可能状態に切り替えるだけで、電子ペーパー１３に表示される情報コードＣが有効期間外のものから有効期間内のものに切り替えられる。このため、電子ペーパー１３に表示される情報コードＣを光学的に読み取った携帯端末２０にて有効期間外であると通知されてから電力供給可能状態に切り替えればよく、携帯端末２０にて有効期間外であると通知されるまで電力供給停止状態であっても問題は生じないので、この点からも消費電力の低減を図ることができる。 As a result, even if the information code C outside the valid period is displayed on the electronic paper 13 because the power supply is stopped, the information code C displayed on the electronic paper 13 is valid only by switching to the power supply enable state. You can switch from the one outside the period to the one within the valid period. Therefore, the mobile terminal 20 that optically reads the information code C displayed on the electronic paper 13 may be notified that the period is out of the valid period, and then the power supplyable state may be switched to. Since there is no problem even if the power supply is stopped until it is notified that it is outside, the power consumption can be reduced from this point as well.
　また、本実施形態に係る情報コード読取システム１では、情報コード表示装置１０に表示された情報コードＣを光学的に読み取る携帯端末２０には、有効期間外の情報コードＣが読み取られた際に、店員等に対して情報コードＣの表示の更新を促す情報等が、表示部２４に画面表示されて報知される（Ｓ１１５）。このため、上記報知を受けた購入者（携帯端末２０のユーザ）は、情報コード表示装置１０に有効期間外の情報コードＣが表示されることを容易に把握することができる。なお、表示部２４は、有効期間外の情報コードＣが読み取られた際に、その旨を報知する「報知部」の一例に相当し得る。 Further, in the information code reading system 1 according to the present embodiment, when the information code C outside the valid period is read by the mobile terminal 20 that optically reads the information code C displayed on the information code display device 10. , Information or the like prompting the clerk or the like to update the display of the information code C is displayed on the screen of the display unit 24 and notified (S115). Therefore, the purchaser (user of the mobile terminal 20) who has received the above notification can easily grasp that the information code C outside the valid period is displayed on the information code display device 10. The display unit 24 may correspond to an example of a "notification unit" that notifies the fact when the information code C outside the valid period is read.
　なお、有効期間外の情報コードＣが読み取られた際には、電力供給可能状態への切り替えを促す情報、例えば、「電源ケーブルをコンセントに差し込んで下さい」等の情報を、表示部２４による表示等を利用して報知してもよい。これにより、その報知を受けた店員等（情報コード表示装置１０の管理者）が電源ケーブルをコンセントに接続して情報コード表示装置１０を電力供給可能状態に切り替えることで、電子ペーパー１３に表示される情報コードＣが有効期間外のものから有効期間内のものに切り替えられるので、有効期間外の情報コードＣが読み取られてしまうという問題を早期に解消することができる。 When the information code C outside the valid period is read, the display unit 24 displays information prompting the user to switch to the power supplyable state, for example, "Please plug the power cable into the outlet". Etc. may be used for notification. As a result, the store clerk or the like (administrator of the information code display device 10) who received the notification connects the power cable to the outlet and switches the information code display device 10 to the power supplyable state, so that the information code display device 10 is displayed on the electronic paper 13. Since the information code C is switched from the one outside the valid period to the one within the valid period, the problem that the information code C outside the valid period is read can be solved at an early stage.
　なお、本開示は上記実施形態及び変形例に限定されるものではなく、例えば、以下のように具体化してもよい。
（１）本開示に係る情報コード表示装置１０は、バッテリを備えることで、電源ケーブルがコンセントに接続されていない場合であっても、バッテリから供給される電力に応じて制御部１１にて上記情報コード表示処理を実施してもよい。このようなバッテリ駆動方式であっても、バッテリからの電力供給が停止した際には、情報コードＣが電子ペーパー１３に画面表示された状態が維持されるため、上記効果を奏する。 The present disclosure is not limited to the above-described embodiment and modification, and may be embodied as follows, for example.
(1) The information code display device 10 according to the present disclosure is provided with a battery, so that even when the power cable is not connected to the outlet, the control unit 11 describes the above according to the power supplied from the battery. Information code display processing may be performed. Even in such a battery-powered system, when the power supply from the battery is stopped, the state in which the information code C is displayed on the screen of the electronic paper 13 is maintained, so that the above effect is obtained.
（２）情報コードＣには、店舗情報等に加えて、その店舗等の住所に相当する位置情報が記録されてもよい。この場合には、携帯端末２０にてなされる決済処理では、ＧＰＳ等を利用して得られる当該携帯端末２０の位置情報と情報コードＣから読み取った位置情報とを照合することができる。このため、情報コードＣから読み取った位置情報から特定される位置と携帯端末２０の現在位置とが大きく異なるような場合には、情報コード表示装置１０が本来設置されている店舗以外で利用されているとして、表示部２４による表示等を利用して注意喚起することができる。これにより、本来使用されない店舗での情報コード表示装置１０の不正使用を防止でき、セキュリティ性を向上することができる。 (2) In the information code C, in addition to the store information and the like, location information corresponding to the address of the store and the like may be recorded. In this case, in the payment process performed by the mobile terminal 20, the position information of the mobile terminal 20 obtained by using GPS or the like can be collated with the position information read from the information code C. Therefore, when the position specified from the position information read from the information code C and the current position of the mobile terminal 20 are significantly different, the information code display device 10 is used in a store other than the store where the information code display device 10 is originally installed. If so, it is possible to call attention by using the display or the like on the display unit 24. As a result, unauthorized use of the information code display device 10 in a store that is not originally used can be prevented, and security can be improved.
