An ID tag that stores information, a sales tag reader that is installed in a merchandise store that sells products and reads identification information from the ID tag, and a payment amount that the management target person should pay for purchasing the product at the merchandise store Payment amount information acquisition means for acquiring payment amount information for specifying, and payment amount information storage means for storing the identification information read by the sales tag reader in association with the payment amount information acquired by the payment amount information acquisition means It is characterized by providing.

  In the product sales system of the present invention configured as described above, when the sales tag reader reads the identification information from the ID tag and the payment amount information acquisition means acquires the payment amount information, the payment amount information storage means reads by the sales tag reader. The identified identification information is stored in association with the payment amount information acquired by the payment amount information acquisition means.

  That is, the merchandise store can charge a purchase price at a later date based on the identification information and the payment amount information stored in the payment amount information storage means. For this reason, the management subject does not have to pay the purchase price when purchasing the product at the product store.

  For this reason, by having the ID tag, the management subject does not need to confirm whether or not he / she has the amount of cash necessary to purchase the product. Further, the guardian of the management subject does not need to have the management subject possess cash.

Furthermore, even if the management subject forgets to bring the necessary amount of cash, the product can be purchased with peace of mind.
In particular, in the product sales system of the present invention, the management target facility is a cram school, the management target person is a cram school student, and the product sales store is a convenience store or a bento restaurant.

  When the tag purchase determination process is executed, the CPU 51 determines whether or not purchase information (that is, purchased product name information, total amount information, and identification information) is received from the cashing register 23 in S310. If the purchase information has not been received (S310: NO), the tag purchase determination process ends.

  On the other hand, when the purchase information is received (S310: YES), the cram student purchase management information corresponding to the identification information included in the received purchase information is extracted from the cram student management database 53b in S320.

  Further, in S330, current time information indicating the current time is generated based on the value of the timer T11. In S340, based on the purchase history in the cram student purchase management information extracted in S320, the identification received in S310 in a predetermined counting time range (for example, from midnight to the current time in the present embodiment). The number of times the school student corresponding to the information purchases at the merchandise store 20 is obtained, and the purchase number information indicating the number of purchases is generated.

  Thereafter, in S350, based on the purchase permission flag F11 in the extracted cram student purchase management information, it is determined whether or not the purchase with the ID tag 15 (hereinafter referred to as ID purchase) is permitted. That is, ID purchase is permitted when the purchase permission flag F11 is set, and ID purchase is prohibited when the purchase permission flag F11 is cleared.

  Thereafter, in S360, it is determined whether or not ID purchase is permitted based on the designated product information in the extracted cram student purchase management information. That is, if the product indicated by the received purchase product name information matches the specified product indicated by the specified product information, ID purchase of this product is permitted, and if not, ID purchase is prohibited. In the present embodiment, food (lunch, bread, drinks, snacks, etc.) is registered in the designated product information.

  Thereafter, in S370, it is determined whether or not ID purchase is permitted based on the upper limit purchase amount information in the extracted cram student purchase management information. That is, if the total amount indicated by the received total amount information is equal to or less than the upper limit purchase amount (for example, 1,000 yen in this embodiment) indicated by the upper limit purchase amount information, ID purchase is permitted and the upper limit purchase is permitted. ID purchase is prohibited when the amount exceeds the limit.

  Thereafter, in S380, it is determined whether or not ID purchase is permitted based on the specified time information in the extracted cram student purchase management information. That is, the current time indicated by the current time information generated in S330 is within the specified time indicated by the specified time information (in this embodiment, for example, 17:00 to 18:00 and 19: 0 to 19:30). ID purchase is permitted, and ID purchase is prohibited when it is outside the specified time.

  Thereafter, in S390, it is determined whether or not ID purchase is permitted based on the upper limit purchase count information in the extracted cram student purchase management information. That is, if the purchase count indicated by the purchase count information generated in S340 is less than the upper limit purchase count (in this embodiment, for example, 2 times) indicated by the upper limit purchase count information, ID purchase is permitted. ID purchase is prohibited when the number of purchases is greater than or equal to the number of purchases.

  Thereafter, in S400, it is determined whether or not ID purchase is permitted based on the determinations in S350 to S390. That is, if it is determined that ID purchase is permitted in all the determinations in S350 to S390, it is determined that ID purchase is permitted, and if it is determined that even one of the determinations in S350 to S390 prohibits ID purchase. Determines that ID purchase is prohibited.

  If it is determined that ID purchase is permitted (S400: YES), the purchase history in the cram student purchase management information extracted in S320 is updated in S410. That is, the received purchase information (that is, purchased product name information and total amount information) is added to the purchase history in association with the current time information generated in S330.

  Thereafter, in S420, the above-described purchase permission information is generated, and this purchase permission information is transmitted to the cashing register 23. Then, the tag purchase determination process ends. On the other hand, if it is determined that ID purchase is prohibited (S400: NO), in S430, the purchase prohibition information including the prohibition reason information indicating the reason determined to be ID purchase prohibition in S350 to S390 is generated. The purchase prohibition information is transmitted to the cashing register 23. Then, the tag purchase determination process ends.

  The reasons for this prohibition are, according to the determination in S350 to S390, “not a school student permitted to purchase ID” (S350), “XX is not a product permitted to purchase ID (XX). ○ is the product name) ”(S360),“ the total purchase price exceeds the upper limit of ○○○ yen (○○○ is the upper limit purchase amount) ”(S370),“ designated time (XX hours) To XX) ”(S380),“ the number of daily purchases exceeds the upper limit ○ (the upper limit purchase number is entered in ○) ”(S390).

  Next, the procedure of the database update process executed by the CPU 51 of the store side management terminal 21 will be described with reference to FIG. FIG. 5B is a flowchart showing database update processing. The database update process is a process that is repeatedly executed while the CPU 51 is activated (powered on).

  When this database update process is executed, the CPU 51 determines whether or not the purchase permitted cram school student list 43b is received from the cram school management terminal 11 in S510. If the purchase-permitted school student list 43b has not been received (S510: NO), the database update process is terminated.

  On the other hand, when the purchase permission school student list 43b is received (S510: YES), the school student purchase management information in the school student management database 53b is updated based on the purchase permission school student list 43b in S520. That is, the purchase permission flag F11 corresponding to the identification information described in the purchase permission cram student list 43b is set, and the purchase permission flag F11 corresponding to the identification information not described in the purchase permission cram student list 43b is cleared. When the update of the school student purchase management information is completed for all the identification information, the database update process is terminated.

  Next, the procedure of the designated product information transmission process executed by the CPU 51 of the store side management terminal 21 will be described with reference to FIG. FIG. 6A is a flowchart showing designated product information transmission processing. The designated product information transmission process is a process that is repeatedly executed while the CPU 51 is activated (powered on).

  When this designated product information transmission process is executed, the CPU 51 sends a designated product information request command for requesting transmission of designated product information corresponding to the identification information from the designated product display device 29 in S610. It is determined whether or not it has been received. If the designated product information request command has not been received (S610: NO), the designated product information transmission process is terminated.

  On the other hand, when the designated product information request command is received (S610: YES), in S620, the designated product information corresponding to the identification information included in the designated product information request command is extracted from the cram school management database 53b and extracted. The designated product information is transmitted to the designated product display device 29. Then, the designated product information transmission process is terminated.

  Next, the procedure of the designated product display process executed by the CPU 81 of the designated product display device 29 will be described with reference to FIG. FIG. 6B is a flowchart showing the designated product display process. The designated product display process is a process repeatedly executed while the CPU 81 is activated (powered on).

  When this designated product display process is executed, the CPU 81 determines whether or not the designated product display flag F21 is set in S710. If the designated product display flag F21 is not set (S710: NO), it is determined whether or not the tag reader 88 has read the identification information from the ID tag 15 in S720. If the identification information has not been read (S720: NO), the designated product display process is terminated.

  On the other hand, when the identification information is read (S720: YES), the above-mentioned designated product information request command including the identification information read by the tag reader 88 is transmitted to the store side management terminal 21. After that, in S740, the process waits until the designated product information is received from the store side management terminal 21.

  When the designated product information is received (S740: YES), display of the designated product based on the received designated product information is started on the LCD 87 in S750. Thereafter, in S760, the designated product display flag F21 is set, and the designated product display process is terminated.

  Returning to S710, if the designated product display flag F21 is set (S710: YES), it is determined in S770 whether or not the ID tag 15 has been extracted from the tag insertion slot. If the ID tag 15 has not been extracted (S770: NO), the designated product display process is terminated.

  On the other hand, if the ID tag 15 is extracted (S770: YES), the display of the designated product on the LCD 87 is terminated in S780. Thereafter, in S790, the designated product display flag F21 is cleared, and the designated product display process is terminated.

  Next, the procedure of exit / exit management processing executed by the CPU 41 of the cram school management terminal 11 will be described with reference to FIG. FIG. 7A is a flowchart showing exit / exit management processing. Further, this exit / exit management process is a process repeatedly executed while the CPU 41 is activated (powered on).

  When this exit / exit management process is executed, the CPU 41 determines whether or not the tag reader 13 has read the identification information from the ID tag 15 in S810. If the identification information is not read (S810: NO), the exit / exit management process is terminated.

  On the other hand, when the identification information is read (S810: YES), the attendance flag F1 corresponding to the identification information read by the tag reader 88 is updated. That is, when the attendance flag F1 is set, the attendance flag F1 is cleared, and when the attendance flag F1 is cleared, the attendance flag F1 is set. In S830, the attendance history corresponding to the identification information read by the tag reader 88 is updated. That is, first, current time information indicating the current time is generated with reference to the timer T1. Then, in the attendance history, when the attendance flag F1 is set in S820, information indicating that the user has attended is added in association with the generated current time information. On the other hand, if the attendance flag F1 is cleared in S820, information indicating that the user has left the office is added in association with the generated current time information. Then, the exit / exit management process ends.

  Next, the procedure of the purchase permission setting process executed by the CPU 41 of the cram school management terminal 11 will be described with reference to FIG. FIG. 7B is a flowchart showing the purchase permission setting process. The purchase permission setting process is a process that is repeatedly executed while the CPU 41 is activated (powered on).

  When this purchase permission setting process is executed, the CPU 41 determines in S910 whether or not the current time has reached a predetermined registration time set in advance (in this embodiment, the closing time of the school 10). If it is determined that the predetermined registration time has not come (S910: NO), the purchase permission setting process is terminated.

  On the other hand, if it is determined that the predetermined registration time has been reached (S910: YES), the purchase-permitted cram school student list 43b is updated based on the attendance flag F1 in the exit / exit management database 43a in S920. In other words, the identification information corresponding to the attendance management information for which the attendance flag F1 is set is added to the purchase permitted cram student list 43b, and the identification information corresponding to the exit management information for which the attendance flag F1 is cleared is added. Delete from the purchase permission school student list 43b. That is, a school student who attended school 10 by the end time is registered as a school student permitted to purchase ID.

In S930, the purchase-permitted school student list 43b updated in S920 is transmitted to the store side management terminal 21, and the purchase permission setting process is terminated.
In the product sales system 1 configured as described above, when the identification information is read from the ID tag 15 by the tag reader 27 and the total amount information is acquired (S20), the purchase corresponding to the identification information read by the tag reader 27 is performed. The acquired total amount information is added to the history (S410).

  That is, the merchandise store 20 can charge the purchase price at a later date based on the total amount information stored in the purchase history corresponding to the identification information. For this reason, the school student does not have to pay the purchase price at the time of purchasing the product at the product store 20.

  For this reason, possessing the ID tag 15 eliminates the need for the school student to check whether he / she possesses an amount of cash necessary to purchase food. In addition, parents of cram school students do not need to have cram students (children) possess cash. Even if a cram school student forgets to bring the necessary amount of cash, they can purchase food with peace of mind.

  In addition, the cram school student should pay the purchase price of goods collectively with the monthly fee of the cram school 10, for example. That is, the merchandise store 20 may charge only the cram school 10 for the purchase price. In this way, the merchandise store 20 does not need to charge for each school student, and the burden of billing for the merchandise store 20 can be reduced.

  Further, in the merchandise sales system 1, based on the identification information read by the tag reader 13, the attendance of the cram school student corresponding to this identification information to the cram school 10 is detected, and this detection result is used as a cram school student's withdrawal history database. 43a is stored (S830). Then, based on the exit / exit history stored in the exit / exit management database 43a, the identification information indicating the attendance detected at the predetermined registration time of the school 10 (the closing time in this embodiment) is used as the purchase permitted school student list. 43b is stored (S920). Thereafter, in the merchandise store 20, ID purchase is prohibited when the identification information read by the tag reader 27 and the identification information stored in the purchase permission school student list 43b do not match (S350, S520).

  Therefore, even if a school student corresponding to the identification information not stored in the purchase permission school student list 43b attempts to purchase a product using the ID tag 15 at the product store 20, the total amount information is not stored (S400: NO).

  That is, a cram school student who has not attended the cram school 10 by the predetermined registration time cannot use the ID tag 15 to purchase a product at the merchandise store 20. For this reason, a cram school student who wants to purchase a product using the ID tag 15 intends to attend the cram school 10 by a predetermined registration time. That is, the attendance rate to the school 10 can be improved. In other words, purchasing a product using the ID tag 15 can be used as a reward for attending the school 10.

  If the predetermined registration time is the start time of the school 10, the product cannot be purchased with the ID tag 15 even if it is late for the start time of the school 10, and if the predetermined registration time is the end time of the school 10, it is late. In this case, the standard for purchasing the product with the ID tag 15 can be set according to the predetermined registration time so that the product can be purchased with the ID tag 15 if attending anyway.

  The merchandise sales system 1 acquires purchased merchandise name information indicating the merchandise desired by the cram students at the merchandise store 20 (S20), and stores the acquired purchased merchandise name information and the cram student management database 53b. If the designated product information does not match, ID purchase is prohibited (S360). That is, even if a cram school student tries to purchase a product that does not match the designated product information stored in the cram school management database 53b using the ID tag 15, the total amount information is not stored (S400: NO).

  For this reason, it can classify | categorize into the goods which can be purchased with the ID tag 15, and the goods which cannot be purchased among the goods currently sold in the merchandise store 20. In the present embodiment, non-food items are not purchased with the ID tag 15.

  Also, the designated product display device 29 displays the designated product based on the designated product information stored in the cram school management database 53b (S750). For this reason, the cram school student can select the product after recognizing the product that can be purchased with the ID tag 15 by visually recognizing the content displayed on the designated product display device 29.

  The merchandise sales system 1 acquires current time information indicating the time when the cram student purchases the merchandise (S330), and the current time indicated by the acquired current time information is the designated time stored in the cram student management database 53b. If it is outside the designated time indicated by the information, ID purchase is prohibited (S380). In other words, even if the cram school student tries to purchase a product using the ID tag 15 at a time outside the specified time range, the total amount information is not stored (S400: NO).

  For this reason, it can classify | categorize into the time slot | zone which can purchase goods with the ID tag 15, and the time slot | zone which cannot be purchased. In other words, it is possible to prevent a cram school student from purchasing a product using the ID tag 15 outside the specified time range.

  For example, for a school student who goes directly to school 10 after school is closed, the time period when the product needs to be purchased with the ID tag 15 is before or after school 10 is started. It may be set within a certain time (17:00 to 18:00 in the present embodiment) or within a certain time after the end of work (19:00 to 19:30 in the present embodiment).

  Further, in the merchandise sales system 1, the total amount information is acquired (S20), and the total amount indicated by the acquired total amount information is equal to or greater than the upper limit purchase amount indicated by the upper limit purchase amount information stored in the cram student management database 53b. If it is, ID purchase is prohibited (S370). That is, even if the cram school student tries to purchase a total amount of the upper limit purchase amount (1,000 yen in the present embodiment) or more in one purchase, the total amount information is not stored (S400: NO). For this reason, it is possible to prevent a cram school student from purchasing a product that is more expensive than necessary.

Even if the ID tag 15 is lost and misused, the damage can be minimized (for example, within the upper limit purchase amount if the damage is completed only once).
For example, what is necessary for a cram student who goes directly to the cram school after school is a food for one meal, so the amount corresponding to the food for one meal may be set as the upper limit purchase price.

  Further, the merchandise sales system 1 counts the number of purchases today for the cram school students identified by the identification information read by the tag reader 27 (S340), and if this purchase count is equal to or greater than the upper limit purchase count, ID purchase is performed. It is prohibited (S380).

  That is, even if the cram school student tries to purchase a product exceeding the upper limit purchase count (twice in this embodiment) within one day using the ID tag, the total amount information is not stored (S400: NO). For this reason, it is possible to prevent a cram school student from purchasing a product exceeding the upper limit purchase count.

  In the merchandise sales system 1, when ID purchase is permitted (prohibited), the display panel 66b and the customer display device 67 display a purchase permission screen (purchase prohibition screen) (S140 (S170)). For this reason, at the time of purchase, the clerk of the merchandise store 20 and the cram school students who have the ID tag 15 can know that ID purchase is permitted (prohibited).
