  In the POS terminal 11 according to the configuration of the first embodiment, a program is configured so that the CPU 31 can execute member registration work for registering sales data of purchased products of members.

  FIG. 7 is a flowchart illustrating the processing procedure of the CPU 31 that executes the member registration work of the POS terminal 11 according to the configuration of the first embodiment.

  First, the CPU 31 waits for a member transaction to be declared as ST (step) 11. Then, it is determined whether or not the card data of the membership card 17 has been read. Here, when the card data of the member card 17 is read by the card reader 18 (ST11-YES), it is determined that the member card 17 is read, and the card data of the member card 17 (member which is member identification information) is determined as ST12. Number) is stored in the member processing memory, and member information is inquired to the host computer 12 via the communication line 15 which is a communication means based on the card data of the member card. Incidentally, when receiving an inquiry from the POS terminal 11, the CPU 61 of the host computer 12 searches for the member information of the member in the member information file 19 based on the member number, and returns the member information to the POS terminal 11 as the inquiry source. It is supposed to be.

  Therefore, the CPU 31 of the POS terminal 11 stores the member number included in the member information responded from the host computer 12 as ST13, the issue flag F1 and the use flag F2 of the sales promotion receipt 100 in the member processing memory of the RAM 33, respectively. In ST14, the issue flag F1 of the sales promotion receipt 100 in the member information stored in the member processing memory of the RAM 33 is checked, and whether the sales promotion receipt 100 is unissued “1” or issued “0” to the member. (Sales promotion receipt issuance determination means).

  If it is determined that the sales promotion receipt 100 has not been issued when the issue flag F1 of the sales promotion receipt 100 is set to “1”, the member name and the sales promotion receipt are issued from the member information as ST15. Information is acquired and displayed on the front display 47 and customer display 48.

  On the other hand, when it is determined that the sales promotion receipt 100 has been issued when the issue flag F1 is reset to “0”, the process proceeds to ST16.

  Next, the purchase merchandise registration process specifically shown in FIG. 8 is executed as ST16. This process is repeatedly executed until a registration closing key (for example, deposit / cash key) for declaring the end of registration of a product purchased by one member is input in ST17.

  First, the CPU 31 of the POS terminal 11 waits for the barcode to be scanned by the scanner 44 as ST31. If the barcode is scanned (ST31-YES), it is determined in ST32 whether the barcode is a barcode of the sales promotion receipt 100 printed on the sales promotion receipt 100.

  If the scanned barcode is the barcode data of the sales promotion receipt 100 (ST32-YES), the use flag F2 stored in the member processing memory is checked as ST33.

  Here, when the use flag F2 is reset to “0” (ST33-NO), since the sales promotion receipt 100 cannot be used at present, the process returns to ST31 and waits for the next barcode data to be scanned. To do.

  On the other hand, when the use flag F2 is set to “1” (ST33-YES), the sales promotion receipt 100 can be used, so the sales promotion receipt number of the sales promotion receipt identification information scanned as ST34 is set. Temporarily stored in the member processing memory of the RAM 33.

  Thereafter, the process returns to ST31 and waits for the next barcode data to be scanned.

  On the other hand, when the barcode scanned in ST32 is not the sales promotion receipt identification information of the sales promotion receipt 100 but the product code displayed on each product as ST35 (ST35-YES), the product is displayed as ST36. Execute the registration process. In this process, the product code, the sales price, the sales score, etc. are stored in the transaction memory of the RAM 33 as transaction data.

  In ST37, the product name, sales price, etc. are displayed on the front display 47 and customer display 48. Then, the current purchase product registration process is terminated.

  Returning to the description of FIG. When the input of the registration tightening key is detected in ST17 (ST17-YES), the registration tightening process is executed as ST18. In this process, for example, when the deposit amount is input by the deposit / cash key, the change amount is calculated by subtracting the total amount in the transaction total memory from the deposit amount, and the store display 47 and the customer plane This is a process of displaying on the display 48 and opening the drawer 45.

  Next, in ST19, the drive of the printer 49 is controlled to print and issue a purchase receipt.

  Thereafter, the issue flag F1 of the sales promotion receipt 100 stored in the member processing memory is checked as ST20. If the issue flag F1 of the sales promotion receipt 100 is “1”, that is, if the sales promotion receipt 100 has not been issued to the member, the sales promotion receipt issuance process is executed as ST21.

  Specifically, the CPU 31 controls the driving of the printer 49 and, as shown in FIG. 9, the message data 101 in the information on the sales promotion receipt 100 and the member number in the member information stored in the member processing memory. The sales promotion receipt 100 in which the member name 102 and the barcode 103 including the sales promotion receipt number and the member number in the sales promotion receipt information are printed is issued.

  On the other hand, if the issue flag F1 of the sales promotion receipt 100 has been reset to “0”, the sales promotion receipt 100 cannot be issued at this time, so this member registration process is terminated.

  Thus, if the CPU 31 issues the sales promotion receipt 100, the issue flag F1 of the sales promotion receipt 100 in the member information stored in the member processing memory as ST22 is issued from “1” indicating non-issued. It is updated to “0” indicating

  In ST23, the member information stored in the member processing memory is transferred to the host computer 12 via the communication line 15. As a result, the CPU 61 of the host computer 12 overwrites the member information of the sales promotion receipt 100 received from the POS terminal 11 with the member information issue flag F1 “1” in the member information file 19 overwritten from “1” to “0”. To do. Then, after the update, a response to the end of the update is returned to the POS terminal 11 that is the member information transmission source.

  The CPU 31 of the POS terminal 11 that has received this update end response clears the member processing memory as ST24 and ends the current member registration operation.

  FIG. 10 is a flowchart showing the processing procedure of the CPU 61 when the sales promotion mail dispatching operation is selected by the host computer 12.

  In this sales promotion mail sending operation, when a sales promotion receipt 100 is issued and a predetermined date within the expiration date is reached, a member who owns the sales promotion receipt 100 is notified of unused sales promotion message information on the sales promotion receipt 100. The program is configured so that a promotion mail (electronic mail) is sent.

  When the sales promotion receipt 100 is issued to the member, the CPU 31 of the POS terminal 11 sets the issue flag F1 to “1” and transmits it to the host computer 12 via the communication line 15 corresponding to the member number. It has become. When the sales promotion receipt 100 is used by the member, the CPU 31 of the POS terminal 11 resets the use flag F1 of the sales promotion receipt 100 to “0” and corresponds to the member number in the member identification information. 15 to the host computer 12.

  The CPU 61 of the host computer 12 uses the received sales promotion receipt identification information of the received issuance flag F1 “1” and use flag F2 “0” as the issuance flag F1 “1” or use flag F2 “for the corresponding member number in the member information file 19. "0" is overwritten and updated.

  First, the CPU 61 of the host computer 12 searches the member information file 19 as ST61 and extracts an unused use flag F2 “1” of the sales promotion receipt 100 registered in the member information file 19.

  In ST 62, the member name and the e-mail address are stored in the RAM 63 corresponding to the member number of the unused use flag F 2 “1” of the sales promotion receipt 100.

  Next, a sales promotion message including the sales promotion receipt number and message prepared in advance in the sales promotion receipt file 20 in ST63, including the member number and member name of each unused member of the sales promotion receipt 100 stored in the RAM 63. Create informational promotional emails.

  After that, an electronic mail address is acquired from the RAM 63 as ST64, and the sales promotion mail text created in the processing of ST63 is transferred to the WWW server 14 using the electronic mail address as a transmission destination via the communication line 15, then The process proceeds to a process of reading data of each unused member of the sales promotion receipt 100.

  Then, the process is repeatedly executed until the unused data cannot be read, and if all the unused data can be read, the process is terminated (sales promotion mail transmission control means).

  When the WWW server 14 receives the sales promotion mail text of the sales promotion message information with the email address of each member as the transmission destination from the host computer 12, the WWW server 14 transmits the sales promotion mail text on the Internet 13. ing.

  Next, the CPU 61 of the host computer 12 constitutes a program for controlling each part in accordance with the procedure shown in the flowchart of FIG. 11 in order to perform sales promotion receipt use work processing. Here, the member information file 19 to be used is configured to store a history of the use flag F2 corresponding to each sales promotion receipt number as sales promotion receipt identification information.

  First, the CPU 31 of the POS terminal 11 waits for scanning of bar code data, which is sales promotion receipt identification information of the sales promotion receipt 100, by the scanner 44 in ST81.

  Then, it is determined whether or not the barcode data of the sales promotion receipt 100 has been input. Here, when the barcode data of the sales promotion receipt 100 is input by the scanner 44 (ST81-YES), the sales promotion receipt number as the sales promotion receipt identification information which is the bar code data of the sales promotion receipt 100 as ST82. Is temporarily stored in the member processing memory of the RAM 33, and the use flag F2 information of the sales promotion receipt number is sent to the host computer 12 via the communication line 15 based on the sales promotion receipt number of the sales promotion receipt 100 (whether it is unused or used). ) Inquiry. Incidentally, when the CPU 61 of the host computer 12 receives an inquiry about the use flag F2 information of the sales promotion receipt number of the POS terminal 11, the CPU 61 searches the member information file 19 for the sales promotion receipt number based on the sales promotion receipt number, The use flag F2 information of the sales promotion receipt number is returned to the POS terminal 11 as the inquiry source.

  Therefore, the CPU 31 of the POS terminal 11 stores the use flag F2 information of the sales promotion receipt number returned from the host computer 12 via the communication line 15 in ST83 in the member processing memory of the RAM 33, and then in ST84 the member of the RAM 33. The use flag F2 of the sales promotion receipt 100 stored in the processing memory is checked to determine whether the use flag F2 of the sales promotion receipt 100 is “1” unused or “0” used (use of sales promotion receipt). Determination means).

  When it is determined that the use flag F2 of the sales promotion receipt 100 is unused “1” as ST84, the CPU 61 acquires the sales promotion receipt information from the member processing memory of the RAM 33 from the sales promotion receipt number as ST85, and The member name, the sales promotion receipt number, and the like are displayed on the front display 47 and the customer display 48.

  On the other hand, if it is determined in ST84 that the use flag F2 is “0”, the sales promotion receipt 100 has already been used in ST86. Then, a message “This sales promotion receipt cannot be used” is displayed on the front display 47 and the customer display 48 and the sales promotion receipt issuance operation is terminated.

  As ST87, the use flag F2 of the sales promotion receipt 100 is reset to the used “0”. Then, the used data whose used flag F2 is “0” used is transferred to the host computer 12 through the communication line 15 in correspondence with the sales promotion receipt number.

  Then, the CPU 61 of the strike computer 13 overwrites the used data of the used “0” with the used flag F2 corresponding to the received sales promotion receipt number over the used flag F2 of the sales promotion receipt number of the member information file 19. To update.

  In the embodiment of the present invention, when the sales promotion receipt 100 is used at the POS terminal 11, the use flag F2 of the member information file 19 of the strike computer 12 is checked by the sales promotion receipt number, thereby preventing unauthorized use. Is possible. Further, as a matter of course, the use history may be managed by the membership number as the barcode data of the sales promotion receipt 100.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can embody by modifying a component in the range which does not deviate from the meaning. For example, the use history of the sales promotion receipt 100 can be managed by the sales promotion receipt number of the sales promotion receipt barcode data.

  In addition, although it has been described that unused sales promotion message information of the sales promotion receipt 100 is distributed by e-mail, each customer may be notified of unused sales promotion message information by direct mail.

  As described above, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the invention at the stage of implementation.
