Description

  Embodiments described herein relate generally to a payment terminal and a program.

  The operating procedure of the payment terminal changes depending on the payment target amount and the balance in the card. In recent years, in addition to credit, payment by electronic money or the like can be supported. For this reason, a difference in operation procedure depending on the type of payment card is added, and the operation becomes more complicated.

  When an error occurs during operation, the payment terminal performs notification by displaying information indicating the error on the display unit. When an error occurs, a user such as an operator confirms the display content on the screen and tells the display content of the display content to the inquiry desk to solve the error.

  However, in a busy situation where there is no inquiry time, the user may forcibly resolve the error regardless of the type of error and proceed to the next process. For example, it is a case where the reset button is pressed and the payment process is restarted from the beginning. In this case, depending on the content of the error, the payment data may remain registered in the card company or the like, so the user needs to request the card company or the like to cancel the payment later. Even in such a case, the user must remember the contents of the error until the error that has occurred is properly processed later.

  However, as time elapses from the occurrence of an error, it becomes difficult for the user to remember the details of the error accurately. Even if the error is output and left on the receipt, the user is likely to lose it. For this reason, when the user later informed the contents of the error to an inquiry desk, a card company, etc., there was a question about the accuracy of the contents, and there was no means to confirm it.

  The problem to be solved by the present invention is to provide a settlement terminal and a program that allow a user to confirm the content of an error that has occurred at an arbitrary time after the error is resolved.

  The payment terminal of the embodiment includes an electronic payment means for performing electronic payment processing, an output means for outputting error information indicating the error when an error occurs in the electronic payment processing, and the error information output by the output means. Storage means for storing, instruction means for instructing re-output of the error information output by the output means, and re-output means for outputting error information stored in the storage means when instructed by the instruction means And comprising.

  Hereinafter, embodiments of a payment terminal and a program will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an overall configuration diagram of an electronic payment system. As shown in FIG. 1, the electronic payment system 1 includes a network system including a payment terminal 10 and a center server 11. The settlement terminal 10 is owned by each store such as a chain store. Each store is provided with one to several tens of payment terminals 10 depending on the size of the store. The center server 11 is provided by a card company.

  The payment terminal 10 is a device that performs a series of processes related to electronic payment. For example, the payment terminal 10 displays a guidance screen as a series of processes related to electronic payment, and performs processing such as receiving input of information to be included in payment data from an operator (user) according to the guidance. Further, the settlement terminal 10 receives customer card information through a reading device such as a built-in magnetic card reader 10a, an externally attached pin pad with IC card reader (hereinafter abbreviated as pin pad) 100, or a non-contact reader / writer device 101. Processing to read and generate payment data together with operator input information is performed.

  The pin pad 100 is an apparatus including an IC card reader unit (not shown) and an input pad 100a for inputting an IC card password. The IC card reader unit reads card information such as a card ID and an expiration date when an IC unit such as a credit card or a debit card comes into contact.

  The non-contact reader / writer device 101 is a device using a short-range wireless communication technology such as NFC (Near Field Communication). The non-contact reader / writer device 101 reads a card ID, electronic money information, and the like as card information from a non-contact type IC card that electronically stores monetary information.

  The center server 11 is a server device managed by the card company. The center server 11 performs a card information authentication process, a settlement data registration process, a money minus process for the settlement amount, and the like.

  For example, in the case of credit payment, the payment terminal 10 generates payment data upon receiving input of data relating to electronic payment from the input unit. Then, the payment terminal 10 is connected to the communication network N and transmits the payment data to the center server 11. The center server 11 performs an authentication process based on the payment data received from the payment terminal 10, and registers the payment data when authentication is established. On the other hand, when the payment terminal 10 receives information indicating that authentication has been established from the center server 11, the payment terminal 10 prints the details of the transaction on a receipt sheet and discharges it, and ends a series of procedures relating to electronic payment.

  Next, the configuration of the payment terminal 10 will be described.

When the operator switches the power switch 22 to the OFF side, the power line is cut and the power supply is stopped.

  A cable connection port for connecting an external device or the like is provided on the back surface of the main body 21. Although not shown, in this example, a pin pad 100 (see FIG. 1), a non-contact reader / writer device 101 (see FIG. 1), and a connection port for connecting to a network device are provided.

  An upper panel 23 that can be opened and closed with respect to the main body 21 is provided on the upper portion of the main body 21. The top panel 23 includes an operation unit 24 and a display unit 25. The operation unit 24 is a touch panel that detects an operator's touch input and outputs a signal to a control circuit inside the main body 21. The display unit 25 is a display such as a liquid crystal that displays a guidance screen, an error screen, operation keys, and the like transmitted from the control circuit. The touch panel is disposed on the display screen. When an operator operates an operator such as an operation key displayed on the display screen, the operation signal is input to the control circuit of the settlement terminal 10.

  Inside the main body 21, a printing unit 27 (see FIG. 3) is provided for printing transaction details, sales reports, error contents, and the like on receipt paper. A roll-shaped receipt sheet is detachably set on the printing unit 27. The printing unit 27 pulls out a predetermined amount of receipt paper from the roll, and prints transaction details, error details, and the like in the drawn area. The receipt paper after printing is discharged from a receipt issuing port 26 provided between the main body 21 and the upper panel 23. Rolled receipt paper can be replaced by opening and closing the top panel 23.

  FIG. 3 is a hardware block diagram of the payment terminal 10. As shown in FIG. 3, the payment terminal 10 includes a CPU (Central Processing Unit) 301, a ROM (Read Only Memory) 302, a RAM (Random Access Memory) 303, an RTC (Real Time Clock) unit 304, a memory unit 305, a controller. 306, and communication I / Fs 307, 308, and 309. The units 301 to 309 are connected to each other by a bus 310. Among these, the CPU 301, the ROM 302, and the RAM 303 are the control unit 30 that controls the settlement terminal 10 as a whole.

  The CPU 301 is a central processing unit. The CPU 301 executes a program and appropriately performs arithmetic processing to control the entire payment terminal 10.

  The ROM 302 is a nonvolatile memory. The ROM 302 stores a fixed program such as a boot program and data.

  The RAM 303 is a volatile memory. The RAM 303 is provided with an area for loading programs and data in the memory unit 305, a work area for temporarily storing the processing results of the CPU 301, and the like.

  The RTC unit 304 measures the current date and time.

  The display data 3051 is screen data used for various processes of the payment terminal 10 and includes an input key serving as an operator. One of the screen data is guidance screen data for guiding operations related to the settlement process.

  Specifically, the guide screen data includes selection screen data, input screen data, instruction screen data, confirmation screen data, message screen data, and the like.

  The selection screen data is guide screen data for allowing an operator to select a card type. The input screen data is guide screen data for allowing an operator to input a transaction amount, a password, and the like. The instruction screen data is guide screen data for instructing the operator to read the card with the card information reading device. The confirmation screen data is guide screen data for displaying settlement contents and allowing the operator to confirm the contents. The message screen data is guide screen data for informing the operator of the operating state of the payment terminal 10 by a message.

  The error output information 3052 includes information necessary for error output, such as error screen layout data, detailed data confirmation screen layout data, and error code correspondence information. When the control unit 30 of the payment terminal 10 detects a deviation from the normal process, the control unit 30 acquires an error code or an error message corresponding to the detected content from the error output information 3052. Then, the control unit 30 incorporates the acquired error code or error message into the layout data of a predetermined error screen to generate error screen data.

  The log information 3053 is a file (log file) where the control unit 30 of the payment terminal 10 sequentially writes its own operation information or the operation information is written.

  The error re-output information 3054 is, or is stored information, error detailed information acquired or generated when the control unit 30 of the payment terminal 10 detects an error for later re-output. Whenever an error occurs, the control unit 30 overwrites the error re-output information 3054 in the memory unit 305 from the previous error detailed information to the latest error detailed information (that is, the latest error information).

  The control program 3055 is a program for causing the payment terminal 10 to perform processing such as payment processing according to a predetermined procedure. The control program 3055 includes a program for re-outputting detailed error information (re-output processing described later).

  In addition, the memory unit 305 stores telephone number information of an inquiry desk at the time of an error, terminal number information of the own device, and the like.

  The controller 306 is connected to the operation unit 24, the display unit 25, the printing unit 27, and the card reading unit 10a. The controller 306 controls input / output of signals or data of the units 24, 25, 27, and 100a.

  The operation unit 24 is a touch panel in this example, and outputs an operation signal of touch input performed by the operator to the display unit 25 and input data to the controller 306.

  The display unit 25 is a liquid crystal display in this example, receives screen data output from the control unit 30 from the controller 306, and displays it on the liquid crystal display screen.

The printing unit 27 receives the print data output from the control unit 30 from the controller 306, and prints the content indicated by the print data on the receipt paper. Specifically, the printing unit 27 controls the rotation of the roll. The receipt paper drawn from the roll is subjected to thermal transfer or the like, and the content indicated by the print data is printed.
The card reading unit 10 a reads card information of the magnetic card and outputs the read data to the controller 306.

  The communication I / F 307 is a communication interface for performing communication with the pin pad 100 (see FIG. 1). When the pin pad 100 is connected to a connection port (not shown) of the payment terminal 10 by a cable, the communication I / F 307 detects the connection of the pin pad 100. Then, communication with the pin pad 100 is established under the control of the control unit 30, and communication is started by a command from the control unit 30.

  The communication I / F 308 is a communication interface for communicating with the non-contact reader / writer device 101 (see FIG. 1). When the contactless reader / writer device 101 is connected to a connection port (not shown) of the payment terminal 10 by a cable, the communication I / F 308 detects the connection of the contactless reader / writer device 101. Then, communication with the non-contact reader / writer device 101 is established under the control of the control unit 30, and communication is started by a command from the control unit 30.

  The communication I / F 309 is a communication interface for performing communication with network devices of the communication network N. When the network device is connected to a connection port (not shown) of the payment terminal 10 by a cable, the communication I / F 309 detects the connection of the network device. Then, communication with the network device is established under the control of the control unit 30, and communication is started by a command from the control unit 30.

  In addition, although illustration is abbreviate | omitted here, the payment terminal 10 has the battery for supplying electric power to each part 301-309, 24, 25, 27, 10a, the power supply part which supplies an operating voltage to a battery, etc. I have. The power switch 22 (see FIG. 2) is connected to the power supply unit. When the operator turns on the power switch 22, the power line becomes conductive, and the power supply unit supplies battery power to the units 301 to 309, 24, 25, 27, and 10a. When the operator turns off the power switch 22, the power supply from the battery is stopped.

  Next, the operation of the payment terminal 10 will be described.

  When the operator turns on the power switch 22, the payment terminal 10 is supplied with battery power from the power supply unit to each unit, and is activated through a predetermined activation process.

  In the startup process, the CPU 301 first reads and executes a boot program in the ROM 302. Subsequently, the CPU 301 sequentially loads an OS (Operating System), an application program, and the like in the control program 3055 of the memory unit 305 into the RAM 303 used as the main storage device and executes them. Then, the settlement terminal 10 displays an initial screen (business selection screen) and waits for input from the operator.

  The job selection screen includes selection keys such as “job”, “total”, “setting”, and “practice”. The “business” key is a selection key for declaring that the operator performs a payment process on the payment terminal 10. The “total” key is a selection key for declaring that the operator totals past transaction histories in the settlement terminal 10. The “setting” key is a selection key for declaring that the operator sets a setting value in the payment terminal 10. The “practice” key is a selection key for declaring that the operator will practice the settlement process on the settlement terminal 10.

  It is assumed that the operator selects a “business” key from these selection keys. Then, the CPU 301 executes a settlement processing program included in the application program, and realizes a functional unit described later.

  FIG. 4 is a functional block diagram of the payment terminal 10. As shown in FIG. 4, the payment terminal 10 executes function units such as an electronic payment unit 400, an output unit 401, a storage unit 402, an instruction unit (including a reception unit) 403, and a re-output unit 404. To achieve.

  The electronic settlement unit 400 performs a process of accepting an input from an operator and advancing electronic settlement processing in a predetermined order.

  The output unit 401 detects an error that has occurred during electronic payment processing, and performs processing for outputting the error information to the display unit 25, the printing unit 27, and the like.

  The storage unit 402 performs processing for storing the error information output by the output unit 401 in the memory unit 305 as error re-output information 3054.

  The instruction unit 403 supplies an operation element for requesting re-output of error information to the display unit 25, and performs a process of accepting an operation signal from the operation element supplied to the display unit 25 as an instruction to re-output error information. .

  Based on the re-output instruction received by the instruction unit 403, the re-output unit 404 performs a process of re-outputting the error re-output information 3054 stored in the memory unit 305 as error information.

  FIG. 5 is a flowchart of the main process related to the payment of the payment terminal 10.

  First, the CPU 301 (electronic settlement unit 400) performs processing number n (n = 1, 2,...) Of processing number 1, processing number 2,..., Processing number n,. The process of N) is started (S1).

  Here, the process number is an identification number of a group of processes given for simplifying the explanation. Specifically, it is an identification number indicating a group of processes including a screen display process and a reception process on the screen, such as a reception process using a selection screen and a reception process using an input screen, which will be described later. Here, the start process number n = 1, the end process number n = N, and the screen on which the process number n is displayed is shown as a screen n.

  In the process of step S1, the CPU 301 (electronic payment unit 400) mainly displays a guidance screen n and performs a process of receiving an input from an operator or the like. In the first round, n = 1 is set, the business list selection screen (screen 1) assigned as the transition destination to the “business” key of the business selection screen (screen 0) is displayed, and the type of card of the operator is indicated. Accept input of information.

  Next, the CPU 301 (electronic settlement unit 400) determines whether or not a signal for proceeding to the next processing number has been received (S2). In the first round, the operator presses a selection key indicating the card type on the job list selection screen. CPU 301 (electronic settlement unit 400) accepts the pressed signal as a signal for proceeding to the next process.

  In other selection screens after the second round, the CPU 301 (electronic settlement unit 400) accepts a selection key pressing signal pressed by the operator as a signal for proceeding to the next process.

  Further, when the guidance screen after the second round is an input screen for the settlement amount or the like, the operator inputs data such as the settlement amount in the input box of the input screen. In this case, the CPU 301 (electronic settlement unit 400) accepts a pressing signal of a confirmation key that the operator presses after inputting data as a signal for proceeding to the next process.

  In addition, when the guidance screen after the second round is a confirmation screen for payment details, the CPU 301 (electronic payment unit 400) displays a press signal of a confirmation key that the operator presses after confirming the payment details for the next processing. As a signal for proceeding to.

  Further, when the guidance screen after the second round is an instruction screen or a message screen, a card information reading device, a network device, or the like transmits a notification signal indicating card information or a settlement result. CPU 301 (electronic settlement unit 400) accepts these notification signals as signals for proceeding to the next process.

  CPU301 (electronic payment part 400) will determine with Yes by the determination process of step S2, if a press signal, a notification signal, etc. are detected. On the other hand, when those signals are not detected, it is determined No in the determination process of step S2, and the process proceeds to step S3.

  In step S3, the CPU 301 (electronic payment unit 400) determines whether or not a reset key pressing signal has been received.

  The reset key is a key for the operator to declare to the CPU 301 (electronic settlement unit 400) that the settlement processing operation is to be performed again from the beginning. The reset key is mainly provided on the instruction screen in the guidance screen.

  The CPU 301 (electronic settlement unit 400) detects a pressing signal that is issued when the operator presses the reset key. When the CPU 301 (electronic settlement unit 400) detects this press signal, it determines Yes in step S3. On the other hand, when the pressing signal is not detected, it is determined as No, and the process proceeds to step S4.

  In step S4, the CPU 301 (electronic settlement unit 400) determines whether or not a return key pressing signal has been received.

  The return key is a key for the operator to declare to the CPU 301 (electronic payment unit 400) that the payment processing screen is returned to the previous screen. The return key is provided mainly on the selection screen, the input screen, the confirmation screen, etc., among the guidance screens.

  The CPU 301 (electronic settlement unit 400) detects a pressing signal that is issued when the operator presses the return key. When the CPU 301 (electronic settlement unit 400) detects a return key pressing signal, it determines Yes in the determination process of step S4. On the other hand, if the return key pressing signal is not detected, the determination in step S4 is No, and the process returns to step S2.

  Hereinafter, the process at the time of Yes determination of each step S2, S3, S4 of CPU301 is demonstrated.

  When the determination is Yes in step S2, the CPU 301 (output unit 401) determines error processing (S5).

  For example, if a confirmation key pressing signal is received on the input screen, if the input data takes a normal value in a predetermined format and a predetermined range, it is determined that error processing is unnecessary and the determination is Yes.

  If a communication signal is received, if the communication signal is a signal indicating normal processing, it is determined Yes that error processing is unnecessary.

  In this example, if a selection key pressing signal is received on the selection screen, it is determined that all error processing is unnecessary and the determination is Yes.

  As described above, when the error process is unnecessary, the CPU 301 (output unit 401) determines Yes in the determination process of step S5, and proceeds to the subsequent process of step S7.

  On the other hand, when error processing is necessary, the CPU 301 (output unit 401) determines No in the determination process of step S5, and proceeds to the process of step S6 to perform error processing. After the error process, the process returns to step S1 to perform the process. The error processing in step S6 will be described in detail later.

  In step S <b> 7, the CPU 301 (electronic payment unit 400) determines whether or not the signal received in step S <b> 1 is a notification signal indicating the settlement result from the center server 11.

  If the signal received in step S1 is not the notification signal, the CPU 301 (electronic payment unit 400) returns to step S1 and sets the next processing number. Then, the processing number display processing and reception processing are performed.

  For example, when a “credit” key is detected as a selection key, the CPU 301 (electronic payment unit 400) sets a processing number related to the input of the payment amount. When the “electronic money” key is detected as the selection key, the CPU 301 (electronic payment unit 400) sets a processing number related to the selection of the type of electronic money.

  Here, the processing number to be set next is extracted by the CPU 301 (electronic settlement unit 400) from correspondence information in which the type of signal that can be accepted in step S1 and the processing number to be set next are associated in advance. To do.

  The processing from step S1 after the second round can also be explained in the same manner as the processing flow explained in the first round. Since the description overlaps, the description is omitted here.

  As described above, the CPU 301 (electronic settlement unit 400) performs the processing of the necessary processing numbers from the processing number 1 in the order shown in the correspondence information in step S1, and reaches the processing number N.

  Thereby, the CPU 301 (electronic payment unit 400) temporarily stores the selection information, input data, card information, etc. received in the processing of each processing number on the RAM 303 and generates them as payment data.

  In addition, after generating payment data, the CPU 301 (electronic payment unit 400) transmits the payment data to the center server 11 to establish electronic payment.

  A series of flows from the generation of payment data to the establishment of electronic payment will be described later with examples.

  Now, in step S7, it is assumed that the CPU 301 (electronic settlement unit 400) determines that the signal received in step S1 is a notification signal indicating the settlement result from the center server 11. In this case, the CPU 301 (electronic settlement unit 400) moves the process to step S8.

  In step S <b> 8, the CPU 301 (electronic payment unit 400) outputs print data indicating transaction details to the print unit 27 and instructs the receipt to be output. In addition, message screen data is output to the display unit 25 to display that the transaction has been completed. After the receipt is output, the CPU 301 (electronic settlement unit 400) ends this processing, displays a job selection screen (screen 0), and waits for input.

  Next, a process when a Yes determination is made in step S3 will be described. This process starts when the operator presses the reset key on an instruction screen or the like.

  The CPU 301 (electronic settlement unit 400) erases a series of data relating to the settlement data created so far from the RAM 303 (S9).

  After erasing the data, the CPU 301 (electronic settlement unit 400) returns to step S1, and sets the first processing number “processing number 1” set as the next processing target when the reset key is pressed in the correspondence information.

  Next, a process when a Yes determination is made in step S4 will be described. This process starts when the operator presses the return key on the selection screen, input screen, confirmation screen, or the like.

  The CPU 301 (electronic settlement unit 400) returns to step S1, and sets the previous processing number as the next processing target.

  The above is the flow of the main process.

  The CPU 301 (electronic payment unit 400) writes the state of the payment terminal 10 to the log file sequentially in time series during the execution of the payment process. When the screen is displayed, the screen code is written, and when there is a key input or signal input, information indicating the operation contents is written together with time information.

  As the contents to be written, for example, when the operator presses the selection key on the selection screen, the screen code of the selection screen, information indicating the type of the pressed selection key, and the like are written. When the operator inputs data such as the payment amount on the input screen, the screen code and payment amount data are written out. If the instruction screen is being displayed, the screen code, card information transmitted from the card information reader, etc. are written out. If the message screen is being displayed, the screen code and the establishment information (establishment number) transmitted from the center server 11 (see FIG. 1) are written out.

  Also, error occurrence information and operation information at the time of error occurrence are written out.

  Subsequently, a series of processes from generation of payment data to establishment of electronic payment will be described with specific examples.

  First, in the process of process number 1, the CPU 301 (electronic settlement unit 400) displays the work list selection screen data of the memory unit 305 on the display unit 25 and accepts an input from the operator.

  In the business list selection screen (screen 1), it is assumed that the operator touches and inputs one of the selection keys of “credit”, “debit”, and “electronic money” indicating the type of card.

  Then, the CPU 301 (electronic payment unit 400) receives the input signal and temporarily stores information indicating the type of the card in the RAM 303 as a part of the payment data.

  Then, the CPU 301 (electronic payment unit 400) refers to the correspondence information, and sets the processing number corresponding to the type of the received input signal as the next processing target.

  For example, when a key input of “credit” or “debit” is received, a process number 2 for performing a process for allowing the operator to input a settlement amount is set.

  Further, when the key input of “electronic money” is received, a processing number 3 for performing processing for causing the operator to select the type of electronic money is set.

  In the process of process number 3, the CPU 301 (electronic settlement unit 400) displays an electronic money type selection screen (screen 3) and accepts an input from the operator. When the CPU 301 (electronic payment unit 400) receives input of information indicating the type of electronic money from the operator, the CPU 301 temporarily stores information indicating the type of electronic money in the RAM 303 as part of the payment data. Then, process number 2 is set as the next process target.

  Subsequently, in the process of process number 2, the CPU 301 (electronic payment unit 400) displays the payment amount input screen data of the memory unit 305 on the display unit 25 and receives an input from the operator.

  It is assumed that the operator inputs the settlement amount on the settlement amount input screen (screen 2). Then, CPU301 (electronic payment part 400) receives the input data.

  Further, the CPU 301 (output unit 401) determines whether there is an abnormality in the data contents. In this example, it is determined whether there is any abnormality in the character format or the range of data.

  When normal, the CPU 301 (electronic payment unit 400) temporarily stores the input data in the RAM 303 as part of the payment data. Then, process number 4 is set as the next process target.

  Subsequently, in the process of process number 4, the CPU 301 (electronic settlement unit 400) displays instruction screen data for prompting card reading in the memory unit 305 on the display unit 25. And the input from the card information reading apparatus corresponding to the card | curd which the operator selected is received.

  It is assumed that the operator inserts a card into the card information reading device and causes the card information reading device to read the card.

  Then, CPU301 (electronic payment part 400) receives the signal about the card information via communication I / F307 (or communication I / F308).

  The CPU 301 (output unit 401) determines whether there is an abnormality in the received content. In this example, it is determined whether the signal indicates a reading error.

  When normal, the CPU 301 (electronic payment unit 400) temporarily stores the card information in the RAM 303 as part of the payment data.

  Then, the processing number 5 is set as the next processing target.

  Subsequently, in the process of process number 5, the CPU 301 (electronic settlement unit 400) displays confirmation screen data on the display unit 25 and accepts an input from the operator.

  The confirmation screen data is generated by the CPU 301 (electronic payment unit 400) by incorporating the payment data temporarily stored in the RAM 303 into the confirmation screen data (layout information) in the memory unit 305.

  It is assumed that the operator touch-inputs a confirmation key on the confirmation screen (screen 5). Then, CPU301 (electronic payment part 400) receives the pressing signal. Then, the CPU 301 (output unit 401) determines that the pressing signal is normal.

  Subsequently, the CPU 301 (electronic payment unit 400) performs processing such as acquiring a terminal number as additional information, and completes payment data on the RAM 303. Then, the CPU 301 (electronic settlement unit 400) sets the processing number 6 as the next processing target.

  Subsequently, the CPU 301 (electronic settlement unit 400) displays message data indicating that the memory unit 305 is communicating on the display unit 25 in the process of process number 6. Then, the center server 11 is requested to perform authentication processing and transaction registration processing, and the settlement data to be processed is transmitted.

  After the transmission, the CPU 301 (electronic settlement unit 400) waits until there is a response from the center server 11. Thereafter, it is assumed that the CPU 301 (electronic settlement unit 400) receives a response signal from the center server 11. Then, the CPU 301 (output unit 401) determines whether there is an abnormality in the received content.

  In this example, it is determined whether or not the signal indicates a communication error or a settlement failure such as insufficient balance. If normal, the CPU 301 (electronic settlement unit 400) sets the processing number (processing number N) corresponding to the signal indicating establishment as the next processing target.

  Subsequently, in the process of process number N, the CPU 301 (electronic settlement unit 400) displays message screen data indicating “settlement has been established. Printing is being performed” or the like in the memory unit 305 on the display unit 25.

  Then, the detailed data including the settlement data in the RAM 303 is output to the printing unit 27 to cause the printing unit 27 to issue a receipt.

  After the receipt is issued, the CPU 301 (electronic settlement unit 400) ends the settlement process, returns to the initial screen (business selection screen), and displays the business selection screen (screen 0) on the display unit 25.

  Note that the above shows an example of the settlement processing, and other processing orders may be taken depending on the type of card. For example, the processing order may be changed or the number of processes and the number of screens may increase or decrease.

  Next, the process of the CPU 301 when an error occurs during the settlement process will be described.

  FIG. 6 is a flowchart of error processing (step S6) in the CPU 301.

  When the CPU 301 (output unit 401) detects an error (step S5: No determination), first, the settlement process is interrupted (S60). In this interruption process, the CPU 301 (output unit 401) temporarily stores the process number being executed in the RAM 303, and sets the process number related to the error process. Further, the generated data up to the process number immediately preceding the process number in which an error has occurred is stored in the RAM 303.

  Subsequently, the CPU 301 (output unit 401) first displays an error screen as error processing (S61).

  In this process, the CPU 301 (output unit 401) acquires from the error output information 3052 an error code or error message corresponding to the detected error. The CPU 301 (output unit 401) acquires error screen layout data from the error output information 3052. Then, the CPU 301 (output unit 401) generates error screen data by incorporating the error code and error message acquired from the error output information 3052 into the layout data, and outputs the error screen (see FIG. 12) to the display unit 25. To do.

  Subsequently, the CPU 301 (storage unit 402) stores the detailed error information in the memory unit 305 as error re-output information 3054 (S62).

  In this process, the CPU 301 (save unit 402) stores the error code and error message acquired from the error output information 3052 in the memory unit 305 as error re-output information 3054. In addition, the CPU 301 (save unit 402) acquires information indicating operation contents in time-series order until an error occurs from the log information 3053, and associates them with an error code or error message to re-output the error to the memory unit 305. Save as information 3054.

  Subsequently, the CPU 301 (output unit 401) determines whether or not the reset key provided on the error screen has been pressed (S63). If it is determined that the reset key has not been pressed (No determination), then the CPU 301 (output unit 401) determines whether or not the return key provided on the error screen has been pressed (S64). If it is determined that the return key is not pressed (No determination), the CPU 301 (output unit 401) returns to step S63 and repeats the determination process.

  If it is determined in step S63 that the reset key has been pressed (Yes determination), the CPU 301 (output unit 401) deletes the transaction data (S65). In this process, all the settlement data on the RAM 303 generated before the occurrence of the error and the saved process number are deleted.

  Then, the error process is terminated, and the process returns to step S1. In the process of step S1, the process number 1 corresponding to the reception of the reset key is set as the next process number, and the settlement process is restarted from the beginning.

  In step S64, the CPU 301 (output unit 401) determines that the return key is pressed (Yes determination). Then, the CPU 301 (output unit 401) returns to the process of step S1, sets the process number at the time of error temporarily saved in the RAM 303 in step S1, and restarts the process from the top of the process. That is, the operator performs the operation again when an error occurs.

  Through the above error processing, information indicating the details of the error is stored in the memory unit 305 as error re-output information 3054.

Next, re-output processing of the error re-output information 3054 in the memory unit 305 will be described.
The re-output process is a process for the operator to check the error content at an arbitrary timing after the end of the settlement process.

  Here, as an example, a mode in which a help key for causing the operator to declare the re-output process is provided on the job selection screen (see FIG. 8) and the start of the re-output process is executed from the help key will be described.

  Hereinafter, the re-output process will be described with reference to a flowchart (FIG. 7) and screen configuration diagrams (FIGS. 8 to 15). The screen parts shown in the screen configuration diagrams (FIGS. 8 to 15) are stored in advance in the memory unit 305 as display data or the like.

  First, the configuration of the job selection screen will be described.

  FIG. 8 is a configuration diagram of a job selection screen provided with a help key.

  The job selection screen G1 shown in FIG. 8 includes a “job” tab T1, a “tabulation” tab T2, a “setting” tab T3, a “practice” tab T4, and a “reprint” tab as selection keys for selecting a job type. T5 is provided. Further, the job selection screen G1 includes a help key K1 as an instruction key for selecting a re-output process.

The operator declares the payment terminal 10 to start the payment process by touch-inputting the “job” tab T1 on the job selection screen G1 displayed on the display unit 25. Alternatively, the start of help processing (mainly re-output processing) is declared by touch-inputting the help key K1.
Next, a processing flow of the CPU 301 when the operator instructs a re-output process from the help key K1 provided on the job selection screen G1 will be described.

FIG. 7 is a flowchart of the re-output process executed by the CPU 301.
First, the CPU 301 (instruction unit 403) outputs the job selection screen G1 including the help key K1 to the display unit 25 (S700).

  Subsequently, the CPU 301 (instruction unit 403) determines whether or not the help key K1 has been pressed (S701). If it is determined in this determination that the help key K1 has not been pressed, the CPU 301 (instruction unit 403) subsequently determines whether or not the “work” tab T1 has been pressed (S702). If it is determined that no selection key is pressed, the CPU 301 (instruction unit 403) returns to the process of step S701 and repeats the determination process.

It is assumed that the operator touches and inputs the help key K1 on the job selection screen G1. Then, the CPU 301 (instruction unit 403) determines Yes in the determination process of step S701.
In this case, the CPU 301 (instruction unit 403) outputs a guidance message screen to the display unit 25 (S703).

Here, the configuration of the guidance message screen will be described.
FIG. 9 is a configuration diagram of a guidance message screen.

The guidance message screen G2 shown in FIG. 9 includes a selection key for causing the operator to select an item to be provided as help. In the drawing, an “error re-output” key K10 is shown as one of the selection keys.
The guidance message screen G2 includes other controls such as a return key K15.

  Here, returning to the flow of FIG. 7, the continuation will be described.

  Subsequent to step S703, the CPU 301 (instruction unit 403) determines whether or not the “error re-output” key K10 has been selected (S704).

  If it is determined that the “error re-output” key K10 is not selected (No determination), the CPU 301 (instruction unit 403) determines whether or not the return key K15 is subsequently pressed (S705).

  In this process, if it is determined that the return key K15 has not been pressed (No determination), the CPU 301 (instruction unit 403) determines whether any other key has been pressed. In FIG. 7, the steps showing the other key determination process and the operation after the other key determination process are omitted for the sake of convenience.

  If no key is pressed, the process returns to the determination process in step S704.

  The CPU 301 (instruction unit 403) detects the type of key touch-input by the operator on the guidance message screen G2 of the display unit 25 by the series of determination processes.

  In the case of Yes determination in step S705, the CPU 301 (instruction unit 403) closes the guidance message screen G2 and returns to the process of step S700.

  On the other hand, the determination in step S704 is Yes, that is, the CPU 301 (instruction unit 403) detects that the “error re-output” key K10 has been selected by the operator. Then, the CPU 301 (instruction unit 403) outputs the menu screen as a user interface and displays it on the display unit 25 (S706).

  Here, the configuration of the menu screen will be described.

  FIG. 10 is a configuration diagram of the menu screen.

  The menu screen G3 shown in FIG. 10 includes a plurality of menu items for allowing the operator to select the detailed contents of the error to be re-output by item. These menu items are provided as selection keys.

  Here, as an example, an “error screen redisplay” key K20, an “error receipt print” key K21, an “inquiry TEL confirmation” key K22, a “time / content display” key K23, and a “terminal number confirmation” key K24 are provided. ing.

  The “error screen redisplay” key K20 is a selection key for instructing the CPU 301 (re-output unit 404) to re-display the error screen output to the display unit 25 when an error occurs. .

  The “error receipt printing” key K21 is a selection key for instructing the CPU 301 (re-output unit 404) to print detailed information on the error on the receipt paper.

  An “inquiry TEL confirmation” key K22 is a selection key for instructing the CPU 301 (re-output unit 404) to display the telephone number of the inquiry desk.

  The “time / content display” key K23 is a selection key for instructing the CPU 301 (re-output unit 404) to display the error occurrence time and the operation content that led to the error occurrence.

  The “terminal number confirmation” key K24 is a selection key for instructing the CPU 301 (re-output unit 404) to display the terminal number of the terminal being used.

  The menu screen G3 is provided with other controls such as a return key K25.

Here, returning to the flow of FIG. 7, the continuation will be described.
Subsequent to step S706, the CPU 301 (instruction unit 403) receives an operation signal from the operator on the menu screen G3 (S707).

  Subsequently, the CPU 301 (instruction unit 403) determines whether or not the received operation signal is an operation signal of the “error receipt printing” key K21 (S708).

  If it is determined in step S708 that the operation signal is the “error receipt printing” key K21 (Yes determination), the CPU 301 (re-output unit 404) reads error information (S709). In this reading process, the CPU 301 (re-output unit 404) reads the detailed error information stored as the error re-output information 3054 of the memory unit 305 into the RAM 303.

  Subsequently, the CPU 301 (re-output unit 404) prints out detailed error information (S710).

  In this process, the CPU 301 (re-output unit 404) reads a message screen indicating that printing is in progress from the memory unit 305 and outputs the message screen to the display unit 25. Further, the CPU 301 (re-output unit 404) generates print data from the detailed error information read out to the RAM 303. Then, the printing unit 27 is instructed to execute printing, and print data is output. As a result of this processing, the detailed error information is printed out on the receipt paper and discharged outside the settlement terminal 10.

  FIG. 11 is a configuration diagram of a message screen indicating that printing is in progress.

  The message screen G4 shown in FIG. 11 includes a character M1 and an illustration M2 indicating that printing is in progress.

  At the end of the process in step S710, the message screen indicating that printing is in progress is closed, and the process returns to step S706.

  In the case of No determination in step S708, the CPU 301 (instruction unit 403) subsequently determines whether or not the received operation signal is an operation signal of the “error screen redisplay” key K20 (S711).

  If it is determined in step S711 that the operation signal is the “error screen redisplay” key K20 (Yes determination), the CPU 301 (re-output unit 404) reads error information (S712). In this reading process, the CPU 301 (re-output unit 404) extracts an error code or error message from the error re-output information 3054 in the memory unit 305 and reads it into the RAM 303. Further, error screen data (layout data) is read out to the RAM 303.

  Subsequently, the CPU 301 (re-output unit 404) outputs an error screen to the display unit 25 (S713). In this process, the CPU 301 (re-output unit 404) generates error screen data by incorporating the error code and error message read into the RAM 303 into the layout data. Then, the CPU 301 (re-output unit 404) outputs the generated error screen to the display unit 25. By this processing, the error screen displayed at the time of the error is displayed again on the display unit 25.

  FIG. 12 is a configuration diagram of an error screen.

  The error screen G5 in FIG. 12 includes an area for displaying an error code and an error message. In this example, an error code J1 and an error message J2 are shown in this area as error information when a communication error occurs during card reading. The error screen G5 includes a reset key K26. When the operator presses the reset key K26, the error screen G5 is closed and the display returns to the menu screen G3.

  After the process of step S713, the CPU 301 (re-output unit 404) determines whether there is an input of the reset key K26 or the execution keys K27, K28, K29 (see FIGS. 13 to 14) (S714). When the input of the reset key K26 or the execution keys K27, K28, and K29 is not detected (No determination), the process waits until it is detected.

  In step S714, when the CPU 301 (re-output unit 404) detects the input of the reset key K26 (Yes determination), the error screen G5 is closed and the process returns to step S706.

  In the case of No determination in step S711, the CPU 301 (instruction unit 403) subsequently determines whether or not the received operation signal is an operation signal of the “query destination TEL confirmation” key K22 (S715).

  If it is determined in step S715 that the operation signal is the “confirm TEL confirmation” key K22 (Yes determination), the CPU 301 (re-output unit 404) reads the telephone number information of the inquiry desk (S716). In this reading process, the CPU 301 (re-output unit 404) reads the inquiry desk phone number information stored in advance in the memory unit 305 into the RAM 303. Also, the confirmation screen data (layout data) for the detailed contents of the error is read out to the RAM 303.

  Subsequently, the CPU 301 (re-output unit 404) outputs a first confirmation screen to the display unit 25 (S717). In this process, the CPU 301 (re-output unit 404) generates the first confirmation screen data about the detailed contents by incorporating the telephone number information of the inquiry desk read into the RAM 303 into the layout data. Then, the CPU 301 (re-output unit 404) outputs the generated first confirmation screen data to the display unit 25.

  FIG. 13 is a configuration diagram of the first confirmation screen.

  The first confirmation screen G6 shown in FIG. 13 includes an information display area. In this area, telephone number information J3 of the inquiry desk is incorporated as illustrated in FIG. The first confirmation screen G6 includes an execution key K27. When the operator presses the execution key K27, the first confirmation screen G6 is closed and the display returns to the menu screen G3.

  After the process of step S717, the CPU 301 (re-output unit 404) proceeds to the determination process of step S714 and determines whether or not the execution key K27 is input. When the input of the execution key K27 is not detected (No determination), the process waits until it is detected.

  In step S714, when the CPU 301 (re-output unit 404) detects the input of the execution key K27 (Yes determination), the first confirmation screen G6 is closed and the process returns to step S706.

  In the case of No determination in step S715, the CPU 301 (instruction unit 403) subsequently determines whether or not the received operation signal is an operation signal of the “time / content display” key K23 (S718).

  When it is determined in step S718 that the operation signal is the “time / content display” key K23 (Yes determination), the CPU 301 (re-output unit 404) reads out the error detailed information (S719).

  In this reading process, the CPU 301 (re-output unit 404) extracts a part of the detailed error information from the error re-output information 3054 in the memory unit 305 in chronological order and reads it to the RAM 303. Also, the confirmation screen data (layout data) for the detailed contents of the error is read out to the RAM 303.

  Subsequently, the CPU 301 (re-output unit 404) outputs a second confirmation screen to the display unit 25 (S720). In this process, the CPU 301 (re-output unit 404) generates a second confirmation screen data by incorporating a part of the detailed error information read into the RAM 303 into the layout data. Then, the CPU 301 (re-output unit 404) outputs the generated second confirmation screen data to the display unit 25.

FIG. 14 is a configuration diagram of the second confirmation screen.
The second confirmation screen G7 shown in FIG. 14 includes an information display area. Detailed error information J4 is incorporated in this area.

  Here, as an example, a state when the error occurrence date and time included in the detailed error information of the memory unit 305 and the operation history in the chronological order at that time are extracted and incorporated is shown. In the operation history in chronological order, the operator selects credits on the business list display screen (see FIG. 8), the operator inputs the settlement amount on the subsequent settlement amount input screen (not shown), and further displays the instruction screen (not shown). It can be seen from the figure that the operator has read the card information.

  The second confirmation screen G7 further includes an execution key K28. When the operator presses the execution key K28, the second confirmation screen G7 is closed and the display returns to the menu screen G3.

  After the process of step S720, the CPU 301 (re-output unit 404) proceeds to the determination process of step S714 and determines whether or not there is an input of the execution key K28. When the input of the execution key K28 is not detected (No determination), it waits until it is detected.

  In step S714, when the CPU 301 (re-output unit 404) detects the input of the execution key K28 (Yes determination), the second confirmation screen G7 is closed and the process returns to step S706.

  In the case of No determination in step S718, the CPU 301 (instruction unit 403) subsequently determines whether or not the received operation signal is an operation signal of the “terminal number confirmation” key K24 (S721).

  If it is determined in step S721 that the operation signal is the “terminal number confirmation” key K24 (Yes determination), the CPU 301 (re-output unit 404) reads the terminal number information (S722). In this reading process, the CPU 301 (re-output unit 404) reads terminal number information stored in advance in the memory unit 305 into the RAM 303. Also, the confirmation screen data (layout data) for the detailed contents of the error is read out to the RAM 303.

  Subsequently, the CPU 301 (re-output unit 404) outputs a third confirmation screen to the display unit 25 (S723). In this process, the CPU 301 (re-output unit 404) generates the third confirmation screen data about the detailed contents by incorporating the terminal number information read into the RAM 303 into the layout data. Then, the CPU 301 (re-output unit 404) outputs the generated third confirmation screen data to the display unit 25.

  FIG. 15 is a configuration diagram of the third confirmation screen.

  The third confirmation screen G8 shown in FIG. 15 includes an information display area. In this area, terminal number information J5 is incorporated as illustrated in FIG. The third confirmation screen G8 includes an execution key K29. When the operator presses the execution key K29, the third confirmation screen G8 is closed and the display returns to the menu screen G3.

  After the process of step S723, the CPU 301 (re-output unit 404) proceeds to the determination process of step S714 and determines whether or not the execution key K29 is input. When the input of the execution key K29 is not detected (No determination), it waits until it is detected.

  In step S714, when the CPU 301 (re-output unit 404) detects the input of the execution key K29 (Yes determination), the third confirmation screen G8 is closed and the process returns to step S706.

  In the case of No determination in step S721, the CPU 301 (re-output unit 404) subsequently determines whether or not the received operation signal is an operation signal for the return key K25 (S724).

  In step S724, when the CPU 301 (re-output unit 404) detects an operation signal of the return key K25 (Yes determination), the menu screen G3 is closed, and the process proceeds to step S703.

  In step S724, in the case of No determination, the CPU 301 (re-output unit 404) proceeds to the process of step S707.

  In the present embodiment, when an error occurs, the latest error detail information is stored as error re-output information 3054 in the memory unit 305. Therefore, when an error occurs, the error detail information of the error that occurred immediately before is overwritten with the error detail information of the error that has newly occurred. As a result, the error re-output information 3054 is always kept to the minimum storage area that can hold only the detailed information of the most recent error, and the use of the memory is suppressed.

  However, the payment terminal of this embodiment is not limited to this. For example, the memory unit may be modified so as to secure a storage area for storing detailed information of the error that has occurred, from the most recent to the previous multiple times. For example, a ring buffer may be used so that when a new error occurs, the detailed information of the oldest error is overwritten with the detailed information of the latest error.

  In this case, it is preferable to further provide an error selection screen in order for the operator to select one error from the error history. The error selection screen is provided as a screen after the operator selects the “error re-output” key K10 on the guidance message screen G2. For example, a plurality of selection keys are provided on this selection screen, and information indicating the date and time of occurrence of an error is assigned to each selection key so as to be displayed.

Then, the operator can select error information to be re-output from the date and time of occurrence of the error, and touch-input the corresponding selection key.
The CPU 301 (re-output unit 404) displays the menu screen G3, and narrows down the error information from the information on the occurrence date and time input by touching by the operator. Then, an error menu item input from the menu screen G3 by the operator is accepted for the narrowed range.

  In the present embodiment, the error screen information output to the display unit 25 at the time of an error is shown as a form in which the CPU 301 (storage unit 402) leaves the memory unit 305 as character information such as an error code or an error message. At the time of re-output, the CPU 301 (re-output unit 404) again incorporates the error code and error message into the screen data, and outputs the reproduced error screen to the display unit 25.

  However, the settlement terminal of the present embodiment does not limit the method for redisplaying the error screen. The CPU 301 (storage unit 402) may be modified to leave an error screen as image data of the screen in the memory unit 305. For example, an error screen including character information such as an error code and an error message is left as image data. In such a case, the CPU 301 (re-output unit 404) causes the display unit 25 to output the image data at the time of re-output.

  In the present embodiment, a mode is shown in which a help key K1 is provided on the job selection screen G1 (see FIG. 8), and the re-output process is started from the help key K1. However, the settlement terminal of the present embodiment does not limit the instruction to start the re-output process to the selection of the help key K1 on the job selection screen G1. For example, the help key K1 may be supplied to another screen of the job selection screen G1, and when the operator presses the help key K1 on the screen, the screen may be changed to the guidance message screen G2.

  Further, instead of the help key K1, it is also possible to perform a modification such as providing a redisplay-only key for directly reading error detailed information on the job selection screen G1 or another screen.

  Various programs used in the settlement terminal of this embodiment and the modification are files in an installable or executable format, such as a CD-ROM, a flexible disk (FD), a CD-R, a DVD (Digital Versatile Disk), etc. The program may be provided by being recorded on a computer-readable recording medium and read into a flash ROM or the like of the settlement terminal for execution.

  Further, the program may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network.

  With the above configuration, in the payment terminal according to the present embodiment and the modified example, it becomes possible for the user to check the content of the error that has occurred (especially the content of the most recent error) at any point after the error has been resolved. . Therefore, even when making an inquiry to the inquiry desk, the details of the error can be accurately communicated, and a third party can confirm it.

  In the above embodiment and modification, although the structure about a payment terminal and a program was demonstrated, this embodiment and modification are shown as an example, and are not intending limiting the range of invention.
