Description

  The present invention calculates points based on, for example, the total amount of merchandise sales data inputted for sale, and writes the points or accumulated points to a storage medium such as a rewrite card, IC card, memory card, magnetic card, RFID tag, or the like. The present invention relates to a merchandise sales data processing apparatus such as a POS (Point Of Sales) terminal and an electronic cash register.

  In recent years, many retail stores have introduced a service point system for the purpose of customer containment. This system is a system in which points are calculated based on the amount of merchandise purchased each time a customer makes a purchase, and the points are accumulated to provide a service corresponding to the accumulated points to the customer. In this service point system, a card-shaped storage medium is normally distributed to each customer, and the accumulated points of the customer are stored in the card-shaped storage medium.

  POS terminals that support such a service point system are already widely used. Generally, this type of POS terminal, when the sales data of the product purchased by the customer is input via the input unit, and when the registration closing is declared by the closing key, the amount of the product purchased by the customer is set to a predetermined amount. The points are calculated by fitting to the calculation formula. Then, the current point is added to the accumulated points up to the previous time read from the storage medium owned by the customer, and the accumulated points after the addition are overwritten on the storage medium.

By the way, if an error occurs when the POS terminal writes the accumulated points to the storage medium, the accumulated points so far may be lost. Therefore, conventionally, if an error occurs when writing information to the card, the customer is notified of the write error by printing it on the receipt, and the customer who receives the notification issues a new card at the service center with the receipt. A technique for performing processing and the like has been known (see, for example, Patent Document 1).
JP 2000-76554 A

  However, conventionally, when a point writing error to a storage medium occurs, the operator inputs the number printed on the receipt at the time of the error and stores it in a new storage medium, so that work takes time. In addition, there is a problem that a point input error may occur. There is also a problem that a waiting time is required because a service counter or the like has to deal with the customer despite discomfort caused by a writing error.

  The present invention has been made based on such circumstances, and the object of the present invention is to provide a product sales data processing apparatus capable of shortening recovery time and improving service when a point writing error to a storage medium occurs. It is something to be offered.

  The present invention relates to a receipt issuing means for issuing a receipt by driving a printer based on product sales data inputted for sale, and a point writing means for calculating a service point based on the product sales data and writing the service point in a storage medium. In the commodity sales data processing apparatus having the above, when a writing error occurs when writing the service point to the storage medium by the point writing means, the data conversion means for converting the service point into code image data, and the means obtained by this means Point code printing means for printing code image data on a receipt paper by a printer.

  According to the present invention in which such measures are taken, it is possible to provide a merchandise sales data processing apparatus capable of shortening the recovery time and improving the service when a point writing error to the storage medium occurs.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment, the present invention is applied to a POS terminal in a store where a card-type storage medium using a rewritable marking technology, that is, a so-called rewritable card is distributed to each customer as a point card. Is the case.

  FIG. 1 is a block diagram showing a main configuration of a POS terminal according to the present embodiment. The POS terminal includes a CPU (Central Processing Unit) 1 as a control unit body. Also, a ROM (Read Only Memory) 2 in which fixed data such as a program is stored in advance, a RAM (Random Access Memory) 3 in which various memory areas necessary for merchandise sales data registration processing and the like are formed, the current date And a clock unit 4 for measuring time, a communication interface 5 for controlling data communication with a store computer connected via a communication line, a keyboard 6 provided with a lock key, etc. A keyboard controller 7 for capturing signals, a display controller 9 for controlling data display on the operator display 8, a display controller 11 for controlling data display on the customer display 10, and a printer 12 for printing on receipt paper; Control the printer controller 13 for issuing various receipts and the scanner 14 for barcodes, A scanner controller 15 that captures canned barcode data, a card reader / writer 16 for a rewrite card, a card reader / writer controller 17 that captures data stored in the point card 20 and writes data to the card 20, etc. It has. The CPU 1, the ROM 2, the RAM 3, the clock unit 4, the communication interface 5, and the controllers 7, 9, 11, 13, 15, and 17 of each input / output device are connected by a bus line 18 such as an address bus or a data bus. .

  In the POS terminal having such a configuration, a business menu screen is displayed on the operator display 8 as an initial state. On this screen, various business menus such as normal registration business, return registration business, inspection business, checkout business, point correction business, etc. are displayed. Thus, when a normal registration job is selected from the job menu screen by a key operation of the keyboard 6, the CPU 1 is configured to execute the processing shown in the flowchart of FIG.

  That is, when sales data of a product purchased by a customer is input by scanning a product barcode with the scanner 14 or a key operation on the keyboard 6, the CPU 1 determines that there is product registration as ST1, and executes product registration processing as ST2. To do. For example, the sales data of the number and price of the registered product are registered in the memory, and the product name, price, etc. of the registered product are displayed on the operator display 8 and the customer display 10.

  The CPU 1 executes a product registration process every time product registration is performed until registration closure is declared. When the tightening key on the keyboard 6 is operated, the CPU 1 determines that there is registered tightening as ST3, and executes a registered tightening process as ST4. For example, when cash deposits are declared for the total amount of goods registered in this transaction, change is calculated by subtracting the total amount from the deposit amount, and the operator display 8 and customer Displayed on the display 10.

  Moreover, CPU1 calculates a point based on the content of this commercial transaction as ST5. For example, an integer part of 10% of the total registered merchandise value is pointed this time. Next, CPU1 judges the presence or absence of the point card 20 as ST6. At this time, if the card data of the point card 20 is not read by the card reader / writer 16, the CPU 1 determines that there is no point card. If there is no point card, the process proceeds to ST10.

  If there is a point card, the CPU 1 takes in the accumulated points from the card data as ST7. In ST8, the current point is added to the accumulated points to calculate a service point. In ST9, the card reader / writer 16 is controlled to overwrite the point card 20 with the service points as accumulated points (point writing means). Thereafter, the process proceeds to ST10.

  In ST10, the CPU 1 causes the receipt sheet on which the detailed data of the commodity registered in the current transaction is printed by the printer 12 as a transaction receipt 30 (see FIG. 3) (receipt issuing means). Thereafter, the CPU 1 determines whether or not a writing error to the card has occurred in ST11. If no write error has occurred, the current processing routine is terminated.

  If a write error has occurred, the CPU 1 converts the service point into bar code data as ST12 (data conversion means). In ST13, various data including the barcode data are printed on the receipt paper by the printer 12, and a point correction receipt 40 (see FIG. 4) is issued (point code printing means). This is the end of the current processing routine.

  Further, when the point correction job is selected from the job menu screen, the CPU 1 is configured to execute the processing shown in the flowchart of FIG.

  That is, when the barcode 41 printed on the point correction receipt 40 is scanned by the scanner 14, the CPU 1 determines the presence of scanning as ST21 and, as ST22, the barcode of the point correction receipt 40 from the barcode data flag. Recognize that it is 41. In ST23, the bar code data is analyzed to obtain service points (point code analyzing means).

  Next, in step ST34, the CPU 1 increases the service point P acquired from the barcode data by the following equation (1) by a preset error point magnification N (N> 1) (point increasing means).

Q (service point after premium) = P x N (1)
Next, CPU1 judges the presence or absence of the point card 20 as ST35. If the point card 20 is not present, the system waits until the point card 20 is attached to the card reader / writer 16.

  If it is determined that the point card 20 is present, the CPU 1 controls the card reader / writer 16 in ST36 to overwrite the additional service point Q on the point card 20 (point rewriting means).

  Next, the CPU 1 determines whether or not a writing error to the card has occurred in ST37. If a write error has occurred, the error is notified and the current processing routine is terminated.

  If no writing error has occurred, the CPU 1 prints the service point before the premium, the service point after the premium, the error point magnification, etc. on the receipt paper by the printer 12 in ST38, and the service point receipt 50 (FIG. 6). Issue). This is the end of the current processing routine.

  As described above, in the POS terminal according to the present embodiment, the sales data of all products purchased by the customer is registered, and when the registration closing is declared, the current point is calculated based on the sales data of the purchased products. The Then, a transaction receipt 30 on which the current point is printed is issued.

  If the point card 20 is attached to the card reader / writer 16, the accumulated points stored in the point card 20 are read into the POS terminal. Incidentally, the total points of the new point card 20 is “0”. When the accumulated points are read, the POS terminal adds the current points to the accumulated points to calculate service points. Then, this service point is overwritten on the point card 20. Therefore, the customer presents the point card 20 to the store clerk each time shopping, whereby the latest accumulated points are stored in the point card. A service corresponding to the accumulated points can be received. However, if an error occurs when a service point is written to the point card 20, the accumulated points so far on the point card 20 may be lost and the service may not be received.

  Therefore, in this embodiment, when an error occurs when writing a service point, a point correction receipt 40 on which the barcode data of the service point is printed is issued. In the case of the point correction receipt 40 shown in FIG. 4, the barcode data 41 indicates a service point [50] obtained by adding the current cumulative point [20] to the previous cumulative point [30].

  Therefore, the customer who has received the point correction receipt 40 shows the point correction receipt 40 to the cashier at the next shopping, for example. The cashier who has received the point correction receipt 40 selects the point correction work before registering the product purchased by the customer. Then, the barcode data 41 printed on the point correction receipt 40 is scanned by the scanner 14, and the new point card 20 is mounted on the card reader / writer 16. By doing this, the point card 20 in which the service point that has caused the previous writing error, that is, the point accumulated by the predetermined error point magnification from the accumulated point so far is written.

  In addition, when the point correction receipt 40 is forgotten at the time of the next shopping, the point card 20 which memorize | stored this time point as a new customer is received. Then, the point card 20 is presented together with the point correction receipt 40 at the time of the next shopping. By doing so, since the accumulated points and the extra points at the time of the error are added to the previous point and written, the points are not lost.

  As described above, according to the present embodiment, even when an error occurs when data is written to the point card 20, the operation of mounting the new point card 20 on the card reader / writer 16 and the point correction receipt 40 are printed. Since the point card 20 can be reissued when an error occurs only by scanning the bar code data 41, the work time required for reissuing the point card 20 can be reduced. In addition, since the point data is input by barcode scanning, there is no possibility of erroneous input.

  Further, since the point card 20 can be reissued at the POS terminal, it is not necessary for the customer to go to the service counter. Moreover, since it can be reissued at any time, there is no time limit. Moreover, since the points can be increased by setting the error point magnification, the serviceability is excellent, and the discomfort given to the customer due to the writing error can be eliminated.

  In the above embodiment, the point card 20 is a rewrite card, but the type of card is not particularly limited, and may be a magnetic card, an IC card, a memory card, or the like. In addition, the present invention can be similarly applied to a case where a service point is written by wireless communication with a POS terminal using a contactless card or a mobile phone with a built-in RFID tag.

  In the above embodiment, the service point is increased by setting the error point magnification. However, the increase method is not limited to this, and for example, a predetermined point is added to the service point to increase. You may do it.

  In the above embodiment, the code image data printed on the point correction receipt 40 is the bar code of the service point. For example, when the member card is included in the data of the point card 20, the member code is also included. It may be converted into code image data and used when the card is reissued. In this case, the code image data may not be a bar code but may be a two-dimensional code having a large amount of information.
