Description

  The present invention relates to a self-checkout terminal device that inactivates a security tag, a self-checkout system, a detector activation state notification method, and a commodity transaction restriction method.

For the purpose of monitoring the taking-out of products that have not been settled conventionally, some stores are provided with a security tag, and a security tag detector is provided at the entrance of the sales floor. Since the security tag attached to the product is removed from the product or inactivated at the time of payment, the detector does not operate when a proper purchase procedure is performed (for example, see Patent Document 1). However, if an unsettled product is taken out of the store, or if the store clerk forgets to deactivate the security tag or fails, the detector is activated.
The detector issues an alarm when it detects a security tag. The store clerk who has received the warning confirms whether or not the product owned by the customer has been settled.

  In recent years, the introduction of self-checkout terminal devices that enable self-checkout by customers, rather than checkout (product checkout) using a cashier terminal device by a cashier in a normal lane, has been promoted. The self-checkout terminal device enables customers who come to the store themselves to perform product registration to payment, thereby contributing to labor saving in the store and shortening the waiting time of the checkout queue.

  However, since there are some customers who conduct fraudulent activities to bring back the goods without paying out the goods, the self-checkout terminal device is indispensable for countering the users. One of the countermeasures against fraud is checking the product weight (see, for example, Patent Documents 2 and 3).

  In the past, inactivation of security tags was an operation performed by the store clerk at the checkout. Security tags have been almost certainly inactivated by the store staff gaining experience. However, in the self-checkout terminal device, since the customer inactivates the security tag, a reliable operation cannot always be expected. For example, when a security tag is deactivated by demagnetization, the demagnetization may fail because the security tag is outside the demagnetization area or there is not enough time in the demagnetization area.

  In such a case, the customer leaves the store with a product with a security tag that has not been inactivated, and the security tag is detected at a security gate near the entrance and an alarm is issued. For this reason, the store clerk or the security guard is forced to call the customer and change the product the customer has. Customers will feel uncomfortable with the confirmation work, but there are some malicious customers among some good-will customers, so confirmation work is unavoidable for the operation of the security system. It is often said.

  The present invention has been made in view of the above points, and reduces a possibility that a customer may feel uncomfortable and can operate a security system, a self-checkout terminal device, a self-checkout system, and a detector An object is to provide an activation state notification method and a commodity transaction restriction method.

  In order to solve the above problem, the self-checkout terminal device is monitored by the monitoring terminal device. The self-checkout terminal device includes product information acquisition means, detected device inactivation means, product weight weighing means, product registration means, detected device detection means, and notification means.

  The product information acquisition unit acquires product information from the product. The detected device inactivating means changes the detected device from the activated state to the deactivated state in response to the acquisition of the product information. The product weight measuring means measures the weight of the product in the product holding unit that holds the product after obtaining the product information. The merchandise registration means compares the weight information specified from the acquired merchandise information with the weighed weight, and registers the merchandise as a payment target when the weighed weight is valid. The detected device detecting means detects that the detected device in the product holding unit is in an activated state. The notifying means notifies the monitoring terminal device of the detection of the activated state of the detected device.

In order to solve the above problem, the self-checkout system includes a self-checkout terminal device and a monitoring terminal device that monitors the self-checkout terminal device.

FIG. 1 is a block diagram of the self-checkout system of the first embodiment.
The self-checkout system 1 is a system that operates a self-checkout terminal device 10 in a store, and includes a self-checkout terminal device 10 and a monitoring terminal device 30. The self-checkout terminal device 10 is a terminal device that is operated by the shopper so that the shopper can settle the product 20 by himself / herself, and is monitored by the monitoring terminal device 30. The monitoring terminal device 30 is a terminal device operated by a store clerk, and monitors the self-checkout terminal device 10.

  The self-checkout terminal device 10 includes a detector inactivation unit 11, a detector detection unit 13, a product weight weighing unit 14, a product registration unit 15, a product information acquisition unit 16, and a notification unit 17. Is provided.

  The product information acquisition unit 16 acquires product information from the product 20 to which the detector 21 is attached. The product information is identification information for identifying the product 20, for example. The self-checkout terminal device 10 can acquire information belonging to the product 20 such as a product name, a product price, a manufacturer, and a product weight by referring to a database (not shown) from the identification information. The product information acquisition means 16 is, for example, a barcode scanner, and in this case, product information is acquired from the barcode. Alternatively, the product information acquisition unit 16 is, for example, an RFID (Radio Frequency Identification) reader / writer. In this case, the product information is acquired from an RFID tag or an IC chip.

  The detector inactivation means 11 changes the detection state of the detector 21 from the activated state to the inactivated state in response to the acquisition of the product information. The detected device 21 is, for example, a security tag including a magnetizable coil, and can change the detected state from the magnetized activated state to the deactivated deactivated state. Alternatively, the detector 21 is, for example, a rewritable RFID tag with a built-in memory, and the detected state can be changed from the activated state to the inactivated state by rewriting data stored in the memory. A security tag is one of the components constituting the security system together with a security gate near the entrance. The security gate detects the activation state of the security tag and notifies the store clerk of the abnormality.

  The product weight measuring unit 14 measures the weight of the product 20 in the product holding unit 12 that holds the product 20 after the product information is acquired. The product holding unit 12 holds the product 20 after the product information is acquired. The product weight weighing means 14 is provided in the vicinity of the plastic bag (the product holding unit 12) for storing the product 20 after the acquisition of the product information of the self-checkout terminal device 10, for example, for the plurality of products 20 stored in the plastic bag. Weigh in bulk.

  The product registration means 15 compares the weight information specified from the acquired product information with the measured weight, and the measured weight is valid (identity between the registered product 20 and the measured product 20 is recognized). In this case, the product 20 is registered as a payment target. The weight information is registered in advance in a database (not shown) corresponding to the product information. The merchandise registration means 15 can identify the weight information with reference to the database from the merchandise information. The merchandise registration means 15 compares the weight information specified from the acquired merchandise information with the weighed weight, and assumes that the weight weighed when the difference is within a predetermined range is valid.

  The detector detection means 13 detects that the detection state of the detector 21 in the product holding unit 12 is in an activated state. The detector detection means 13 is, for example, provided in the vicinity of a plastic bag for storing the product 20 after the acquisition of the product information of the self-checkout terminal device 10, and a plurality of products 20 stored in the plastic bag are collectively detected. It is possible to detect that the detected state of the vessel 21 is in the activated state.

  The notification means 17 notifies the monitoring terminal device 30 of detection of the activation state of the detected device 21. The communication means for notification from the self-checkout terminal device 10 to the monitoring terminal device 30 may be a communication line that outputs information in one direction or a communication line that can communicate in both directions.

Thereby, the self-checkout terminal device 10 can reduce the possibility that the customer feels uncomfortable and can operate the security system.
The self-checkout terminal device 10 may include product information acquisition restriction means for restricting the acquisition of the product information from the product 20 by the product information acquisition means 16 upon detection of the activation state of the detected device 21. it can. As a result, the customer cannot acquire the product information for the next product 20 and the product cannot be settled. This reduces the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable. .

  In addition, the self-checkout terminal device 10 may include a product registration restriction unit that receives the detection of the activation state of the detected device 21 and restricts the registration of the product 20 by the product registration unit 15 to the settlement target. As a result, the customer cannot register the product information for the next product 20, and the product cannot be settled. This reduces the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable. .

  In addition, the self-checkout terminal device 10 may include a product checkout limiting unit that receives the detection of the activation state of the detected device 21 and limits the checkout of the product 20 registered as a checkout target. As a result, the customer cannot settle the merchandise, and the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable is reduced.

  Further, the self-checkout terminal apparatus 10 may include a notification unit that notifies the shopper of the detection of the activated state of the detected device 21 instead of or in addition to the notification unit 17. For example, the self-checkout terminal device 10 can perform notification by display on the monitor 111 or notification by sound from a speaker (not shown). Thereby, the customer can know in advance that the security tag is in an inactivated state, and the possibility that the security gate detects the activated state of the security tag and makes the customer feel uncomfortable is reduced.

  Next, a more specific second embodiment will be described. The self-checkout system 2 will be described with reference to FIG. FIG. 2 is a diagram illustrating a self-checkout system according to the second embodiment.

  The self-checkout system 2 includes a self-checkout terminal device 100, a monitoring terminal device 200, a POS (Point Of Sale) server 300, and a network 400 that connects these to be communicable.

  The self-checkout system 2 is a system that operates the self-checkout terminal device 100 in a store that sells products 20 such as a supermarket. The self-checkout system 2 includes one or more (for example, four) self-checkout terminal devices 100 and one monitoring terminal device 200. The self-checkout terminal device 100 provides a service that enables self-checkout by a customer. The monitoring terminal device 200 performs customer services such as fraud monitoring by a customer who uses the self-checkout terminal device 100, operation guidance for an unguided customer, and correction of an erroneous operation of the customer.

  In the security system operated together with the self-checkout system 2, it is detected that the product 20 with the activated security tag is taken out of the store. The self-checkout system 2 deactivates a security tag that is in an activated state at the time of merchandise settlement, thereby excluding the merchandise 20 that has already been settled from being monitored for taking out of the store.

  Further, the self-checkout system 2 monitors the weight of the product 20 put in the shopping bag. The self-checkout terminal device 100 detects fraud by comparing the weight of the product 20 placed in the shopping bag with the weight of the product 20 registered as a payment target. Therefore, the self-checkout system 2 includes a data file (product weight file) that associates the product 20 with the weight of the product 20. Then, the self-checkout system 2 grasps the weight of the product 20 based on the product arrival information obtained when the product is received and the weight of the product 20 by the scale provided in the self-checkout terminal device 100. Corresponds to the weight of.

  The POS server 300 centrally manages the sales information registered by the self-checkout terminal device 100, and identifies a product code (product identification information), product name (product name information) and price (price information) for identifying the product 20. The product master (product information file) and the weight master (product weight file) in which are registered are managed. The self-checkout terminal device 100 also includes a product master and a weight master, and manages them in synchronization with the product master and the weight master included in the POS server 300 or another self-checkout terminal device 100.

Next, an overview of the self-checkout terminal device 100 will be described with reference to FIG. FIG. 3 is a diagram illustrating an overview of the self-checkout terminal device according to the second embodiment.
The self-checkout terminal device 100 is a terminal for a customer to pay for the product 20 by himself / herself. The self-checkout terminal device 100 includes a monitor 111, a touch panel 112, a monitoring camera 113, a plastic bag suspension unit 114, a coin deposit / withdrawal unit 115, a total weight weighing scale 116, a security tag detector 117, a coin return port 118, shopping A car placing table 119, a banknote deposit / withdrawal port 120, a demagnetizer 121, an individual weight weighing scale 122, a scanner 123, a printer (for receipt) 124, and a credit card insertion port 125 are provided.

  The shopping basket mounting table 119 is a table on which a shopping basket in which the customer puts the product 20 before payment is placed. The scanner (barcode scanner) 123 irradiates the product 20 with a laser scanning line and reads the barcode attached to the product 20. The self-checkout terminal device 100 registers the product 20 as a payment target based on the read information. The monitor 111 displays information accompanying the settlement of the product 20 such as a product name, a product unit price, and a product weight based on the read barcode. When the product 20 is not associated with the product weight, guidance display is performed so that the product 20 is placed on the individual weight weighing scale 122 and the weight of the product 20 is measured. Further, a guidance display for selecting a product for paying out the product 20 without the barcode is displayed. For example, the monitor 111 performs category display such as sugar beet and fresh food, display of individual product names, quantity display, and the like in the guide display for product selection. At this time, the customer can perform a selection operation on the touch panel 112 according to the guidance display on the monitor 111. The self-checkout terminal device 100 can perform settlement for the product 20 that is not attached with a barcode by a customer selection operation.

  The demagnetizer 121 demagnetizes the security tag (changes the detected state of the detected device 21 from the activated state to the inactivated state). The security tag includes, for example, a magnetizable coil, and is either in a magnetized activated state and in a demagnetized inactivated state, or from a magnetized activated state to an inactivated demagnetized state. The detected state can be changed in the direction. The demagnetizer 121 has a predetermined demagnetization range. The predetermined demagnetization range is set so as to substantially overlap the barcode reading range (laser scanning line irradiation light detection range) of the scanner 123. The self-checkout terminal device 100 demagnetizes the security tag attached to the product 20 (for example, attached) when the barcode of the product 20 is read. Demagnetization can be performed, for example, by AC demagnetization. Further, the change from the activated state to the inactivated state can be performed by physical destruction of the coil, sticking of a shield member, or the like instead of demagnetization.

  The monitoring camera 113 captures a hand that the customer pays out and displays a captured image on the monitor of the monitoring terminal device 200 in the vicinity of the self-checkout terminal device 100. The taken image is used for operation guidance to customers who do not know the operation method in addition to countermeasures against fraud. The product 20 registered as a payment target is placed in a plastic bag suspended from the plastic bag suspension unit 114, and the total weight of the product 20 registered as a payment target is measured by the total weight weighing scale 116. If the difference between the weight of the individual product 20 and the weight increment measured by the total weight weighing scale 116 is within a predetermined allowable range, the self-checkout terminal device 100 registers the product 20 as a settlement target.

  The security tag detector 117 detects the activation state of the security tag attached to the product 20 stored in the shopping bag suspended from the shopping bag suspension part 114. The security tag activation state detection range of the security tag detector 117 is a range in which the product 20 stored in the plastic bag suspended from the plastic bag suspension part 114 can be detected. Further, the security tag detector 117 is not stored in the shopping bag, and the product 20 placed on the total weight weighing scale 116 is also set as the detection range. In addition, what is necessary is just to provide the activation state detection range of the security tag of the security tag detector 117 in a suitable location in order to detect the goods 20 after registration as a payment object. The self-checkout terminal device 100 may be provided with a plurality of security tag detectors 117.

  The customer can perform settlement by inserting a credit card into the credit card insertion slot 125, inserting coins into the coin deposit / withdrawal unit 115, and inserting banknotes into the banknote deposit / withdrawal slot 120. At this time, the coin that could not be received is returned from the coin return port 118. When change occurs, the self-checkout terminal device 100 pays out change by paying out a coin from the coin deposit / withdrawal unit 115 and paying out a bill from the bill deposit / withdrawal port 120. The self-checkout terminal device 100 prints the payment history with the printer 124 and issues a receipt.

If there is no approval from the monitoring terminal device 200, the self-checkout terminal device 100 proceeds to step S38, and if there is an approval from the monitoring terminal device 200, the product check process ends.

[Step S38] The self-checkout terminal device 100 stops the transaction and ends the product registration process.
In this way, the self-checkout terminal device 100 checks the product weight at the time of registering the product and takes a countermeasure against fraud. Therefore, since the product for which the product registration process has been completed is placed at a position where the weight can be weighed by the total weight weighing scale 116, the security tag having the detection range here indicates the activation state of the security tag detector 117. Can be detected.

  Next, security tag detection signal control processing executed by the self-checkout terminal apparatus 100 will be described with reference to FIG. FIG. 8 is a flowchart of security tag detection signal control processing executed by the self-checkout terminal device according to the second embodiment.

  [Step S41] The self-checkout terminal apparatus 100 determines whether or not the security tag detector 117 has detected the activation state of the security tag. If the security tag detector 117 detects the activation state of the security tag, the self-checkout terminal device 100 proceeds to step S42. On the other hand, if the security tag detector 117 does not detect the activation state of the security tag, the self-checkout terminal device 100 proceeds to step S43.

  [Step S42] The self-checkout terminal device 100 sets a security tag detection signal. For example, the self-checkout terminal apparatus 100 sets “1” in the security tag detection flag.

  [Step S43] The self-checkout terminal device 100 clears the security tag detection signal. For example, the self-checkout terminal apparatus 100 sets “0” in the security tag detection flag.

  [Step S44] The self-checkout terminal device 100 proceeds to step S41 when the end condition is not satisfied, and ends the security tag detection signal control process when the end condition is satisfied.

Thus, the security tag detection signal whose state is updated is referred to in the barcode scanning process.
Next, the product registration confirmation process executed by the monitoring terminal device 200 will be described with reference to FIGS. FIG. 9 is a flowchart of a product registration confirmation process executed by the monitoring terminal device according to the second embodiment. FIG. 10 is a diagram illustrating an example of a screen display displayed on the monitor of the monitoring terminal device according to the second embodiment. Note that the monitoring terminal device 200 monitors a plurality of self-checkout terminal devices 100, but in order to facilitate the description, a product registration confirmation process for one self-checkout terminal device 100 will be described. The monitoring terminal device 200 can confirm the product registration of all the self-checkout terminal devices 100 under monitoring by switching the self-checkout terminal devices 100 to be monitored and repeating the product registration confirmation process for the number of units. it can. The monitoring terminal device 200 includes a monitor, and the monitor display screen is divided into a plurality of parts so that the states of the plurality of self-checkout terminal apparatuses 100 can be displayed.

  [Step S51] The monitoring terminal device 200 determines whether or not a product is registered in the self-checkout terminal device 100 to be monitored. The monitoring terminal device 200 acquires information for determining whether or not a product has been registered in the self-checkout terminal device 100 to be monitored from the self-checkout terminal device 100 via the network 400 by communication. The monitoring terminal device 200 proceeds to step S52 when the product is registered in the monitored self-checkout terminal device 100, and proceeds to step S53 when the product is not registered.

  [Step S52] The monitoring terminal device 200 displays the product information of the product 20 registered as a checkout target in the self-checkout terminal device 100 to be monitored on the monitor, and proceeds to step S51. For example, one of the divided displays of the monitor display screen is a screen display 600. The monitoring terminal device 200 displays the product information 601 on the screen display 600. The product information 601 includes, as registered product information, a product name “apple”, a unit price “100 (yen)”, a quantity “1”, and a total price (total price) “100 (yen)”. The product information 601 includes the product name “mandarin orange”, the unit price “80 (yen)”, the quantity “10”, and the total price (total price) “800 (yen)” as registered product information. The product information 601 includes the product name “melon”, the unit price “3000 (yen)”, the quantity “1”, and the total price (total price) “3000 (yen)” as registered product information. The product information 601 includes the product name “banana”, the unit price “200 (yen)”, the quantity “1”, and the total price (total price) “200 (yen)” as registered product information.

  [Step S53] The monitoring terminal device 200 determines whether alarm information has been received from the self-checkout terminal device 100 to be monitored. The monitoring terminal device 200 proceeds to step S54 when the alarm information is received from the self-checkout terminal device 100 to be monitored, and proceeds to step S51 when the alarm information is not received.

  [Step S54] The monitoring terminal device 200 displays alarm information display (button display of the security tag alarm 602) on the screen display 600. The store clerk operating the monitoring terminal device 200 knows from the alarm information display that the security tag in the activated state is detected in the self-checkout terminal device 100 to be monitored.

  Thereby, the store clerk can go to the self-checkout terminal device 100 to be monitored and check the situation. The status confirmation may be performed by voice conversation or message exchange on a monitor using a communication function between the monitoring terminal device 200 and the self-checkout terminal device 100. If necessary, the store clerk can degauss the activated security tag using the handy type demagnetizer or the demagnetizer 121 included in the self-checkout terminal device 100.

  Further, since the product information 601 of the registered product 20 is displayed on the screen display 600, the store clerk can easily grasp which product 20 is attached with the security tag to be degaussed. In addition, by including the product registration order (for example, No.) in the product information 601, the store clerk can grasp the product 20 registered most recently, and to which product 20 the security tag to be degaussed is attached. You can easily grasp what is happening.

  [Step S55] The monitoring terminal apparatus 200 waits for degaussing confirmation and proceeds to step S56. The demagnetization confirmation is performed, for example, by receiving a touch (input) of the button display of the security tag alarm 602 by a store clerk. The monitor included in the monitoring terminal device 200 is also a touch panel, and the display of the button display of the security tag alarm 602 is erased when the store clerk touches it.

  [Step S56] The monitoring terminal device 200 determines whether or not the security tag detection signal of the self-checkout terminal device 100 to be monitored has been cleared. If the security tag detection signal of the monitored self-checkout terminal device 100 is cleared, the monitoring terminal device 200 proceeds to step S57. On the other hand, when the security tag detection signal of the self-checkout terminal device 100 to be monitored is not cleared, the monitoring terminal device 200 waits for the security tag detection signal to be cleared. Whether or not the security tag detection signal is cleared may be determined by the security tag detection signal that the self-checkout terminal device 100 to be monitored transmits periodically or by an event trigger. Alternatively, whether or not the security tag detection signal is cleared may be determined by the monitoring terminal device 200 inquiring of the self-checkout terminal device 100 to be monitored about the state of the security tag detection signal.

[Step S57] The monitoring terminal apparatus 200 proceeds to step S51 when the end condition is not satisfied, and ends the product registration confirmation process when the end condition is satisfied.
In this way, since the store clerk can know that the customer has failed to demagnetize the security tag, the self-checkout system 2 can reduce the possibility that the customer will feel uncomfortable and can operate the security system. To do. In addition, according to such a self-checkout system 2, it leads also to reduction of the work burden of the shop assistant corresponding to the customer who detected the security tag by the security gate.

  Next, a third embodiment in which the operation of the self-checkout terminal device is restricted by an instruction from the monitoring terminal device will be described. FIG. 11 is a block diagram of a self-checkout system according to the third embodiment.

  The self-checkout system 3 is a system that operates the self-checkout terminal device 40 in the store, and includes a plurality of self-checkout terminal devices 40 and a monitoring terminal device 50. The third embodiment differs from the above-described embodiment in that the self-checkout terminal device 40 receives an instruction from the monitoring terminal device 50 regarding the restriction on the acquisition of product information.

Among the configurations included in the self-checkout terminal device 40, the same configurations as those of the self-checkout terminal device 10 described in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
The product information acquisition restriction unit 41 receives the product information acquisition restriction instruction from the monitoring terminal device 50 and restricts the acquisition of the product information from the product 20 by the product information acquisition unit 16. As a result, the customer cannot acquire the product information for the next product 20 and the product cannot be settled. This reduces the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable. .

  The monitoring terminal device 50 includes an instruction control unit 51 and a communication unit 52. The instruction control means 51 controls the output destination (any of the plurality of self-checkout terminal devices 40) and output timing of the instruction for obtaining product information. The communication means 52 communicates with the plurality of self-checkout terminal devices 40 in both directions.

  In such a self-checkout system 3, the monitoring terminal device 50 can control restrictions on acquisition of product information of the self-checkout terminal device 40. In this way, when the monitoring terminal device 50 targets a plurality of self-checkout terminal devices 40, the monitoring terminal device 50 can determine the order in which an abnormality (detection of an activated security tag) is dealt with. .

  Note that the self-checkout terminal device 40 may include a product registration restriction unit instead of the product information acquisition restriction unit 41 or in addition to the product information acquisition restriction unit 41. The product registration restriction unit receives a product registration restriction instruction from the monitoring terminal device 50 and restricts the registration of the product 20 to the settlement target by the product registration unit 45. As a result, the customer cannot register the product information for the next product 20, and the product cannot be settled. This reduces the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable. .

  Further, the self-checkout terminal device 40 may include a product settlement limiting unit instead of the product information acquisition limiting unit 41 or in addition to the product information acquisition limiting unit 41. The product checkout limiting unit receives a product checkout restriction instruction from the monitoring terminal device 50 and limits the checkout of the product 20 registered as a checkout target. As a result, the customer cannot settle the merchandise, and the possibility that the security gate detects the activation state of the security tag and makes the customer feel uncomfortable is reduced.

  Further, the self-checkout terminal device 40 may include all or some of the product information acquisition restriction unit 41, the product registration restriction unit, and the product settlement restriction unit. In that case, the instruction control unit 51 of the monitoring terminal device 50 instructs the product information acquisition restriction unit 41, the product registration restriction unit, and the product settlement restriction unit to receive product information acquisition restriction, product registration restriction, and product settlement restriction, respectively. The instructions are given.

  In addition, the self-checkout terminal device 40 is not limited to the product transaction restriction by the product information acquisition restricting unit 41, the product registration restricting unit, and the product checkout restricting unit. For example, product transactions may be restricted.

  Next, security tag detection signal control processing executed by the self-checkout terminal device 40 will be described with reference to FIG. FIG. 12 is a flowchart of security tag detection signal control processing executed by the self-checkout terminal device according to the third embodiment.

  [Step S61] The self-checkout terminal device 40 determines whether or not the security tag detector 117 detects the activation state of the security tag. If the security tag detector 117 detects the activation state of the security tag, the self-checkout terminal device 40 proceeds to step S62. On the other hand, if the security tag detector 117 does not detect the activation state of the security tag, the self-checkout terminal device 40 proceeds to step S63.

  [Step S62] The self-checkout terminal device 40 transmits a security tag detection signal (a signal indicating that the activation state of the security tag is detected) to the monitoring terminal device 50.

  [Step S63] The self-checkout terminal device 40 transmits a security tag non-detection signal (a signal indicating that the activation state of the security tag is not detected) to the monitoring terminal device 50.

  [Step S64] If the termination condition is not satisfied, the self-checkout terminal device 40 proceeds to step S61. If the termination condition is satisfied, the self-checkout terminal device 40 ends the security tag detection signal control process.

  In this manner, the security tag detection signal or the security tag non-detection signal transmitted to the monitoring terminal device 50 is referred to in the product registration confirmation process executed by the monitoring terminal device 50.

  Next, barcode scanning processing executed by the self-checkout terminal device 40 will be described with reference to FIG. FIG. 13 is a flowchart of barcode scanning processing executed by the self-checkout terminal device according to the third embodiment.

  [Step S <b> 71] The self-checkout terminal device 40 determines whether or not barcode scanning (acquisition of barcode data) is permitted from the monitoring terminal device 50. The self-checkout terminal device 40 proceeds to step S72 when bar code scanning is permitted. On the other hand, the self-checkout terminal device 40 proceeds to step S76 when the barcode scanning is not permitted.

  [Step S <b> 72] The self-checkout terminal device 40 determines whether or not barcode data is acquired from the scanner 123. If the barcode data is acquired from the scanner 123, the self-checkout terminal device 40 proceeds to step S73. On the other hand, if the barcode data is not acquired from the scanner 123, the self-checkout terminal device 40 proceeds to step S76.

[Step S73] The self-checkout terminal device 40 prohibits reading of the barcode by the scanner 123 in order to avoid duplicate reading of the barcode from the product 20.
[Step S74] The self-checkout terminal device 40 executes a product registration process for registering the product 20 for which the barcode has been acquired as a payment target.

[Step S75] The self-checkout terminal device 40 permits bar code reading by the prohibited scanner 123.
[Step S76] If the end condition is not satisfied, the self-checkout terminal device 40 proceeds to step S71. If the end condition is satisfied, the self-checkout terminal device 40 ends the barcode scanning process.

  In this way, the self-checkout terminal device 40 registers the product 20 for which the barcode has been acquired as a payment target. In addition, since the self-checkout terminal device 40 does not execute barcode scanning without obtaining permission from the monitoring terminal device 50, the customer cannot register the product 20 for the next product 20 and the shopping (product transaction) is interrupted. . In this way, the monitoring terminal device 50 can control the interruption of the commodity transaction of the self-checkout terminal device 40.

  Next, the merchandise registration confirmation process executed by the monitoring terminal device 50 will be described with reference to FIGS. FIG. 14 is a flowchart of product registration confirmation processing executed by the monitoring terminal device according to the third embodiment. FIG. 15 is a diagram illustrating an example of a screen display displayed on the monitor of the monitoring terminal device according to the third embodiment. Note that the monitoring terminal device 50 monitors a plurality of self-checkout terminal devices 40, but in order to facilitate the explanation, a product registration confirmation process for one self-checkout terminal device 40 will be described. The monitoring terminal device 50 can confirm the product registration of all the self-checkout terminal devices 40 under monitoring by switching the self-checkout terminal devices 40 to be monitored and repeating the product registration confirmation process for the number of the devices. it can. The monitoring terminal device 50 includes a monitor, and the screen display 610 of the monitor is divided into a plurality of parts so that the states of the plurality of self-checkout terminal devices 40 can be displayed. The screen display 610 shows a state in which the divided screen displays 611, 612, 613, and 614 are divided into four parts and the states of up to four self-checkout terminal devices 40 are displayed.

  [Step S81] The monitoring terminal device 50 determines whether or not a product has been registered in the self-checkout terminal device 40 to be monitored. The monitoring terminal device 50 acquires information for determining whether or not a product has been registered in the self-checkout terminal device 40 to be monitored from the self-checkout terminal device 40 via the network 400 by communication. The monitoring terminal device 50 proceeds to step S82 when the product is registered in the self-checkout terminal device 40 to be monitored, and proceeds to step S83 when there is no product registration.

  [Step S82] The monitoring terminal device 50 displays the product information of the product 20 registered as a checkout target in the self-checkout terminal device 40 to be monitored on the monitor, and proceeds to step S81.

  [Step S83] The monitoring terminal device 50 determines whether or not a security tag detection signal has been received from the self-checkout terminal device 40 to be monitored. The monitoring terminal device 50 proceeds to step S84 when the security tag detection signal is received from the self-checkout terminal device 40 to be monitored, and proceeds to step S81 when the security tag detection signal is not received.

[Step S84] The monitoring terminal device 50 transmits a barcode scan non-permission signal to the monitored self-checkout terminal device 40.
[Step S85] The monitoring terminal device 50 displays alarm information display (button display of security tag alarms 615 and 616) on the screen display 610. The store clerk operating the monitoring terminal device 50 knows from the alarm information display that a security tag in the activated state is detected in the self-checkout terminal device 40 to be monitored. Moreover, the monitoring terminal device 50 can determine the security tag detection order of the activated state in the plurality of self-checkout terminal devices 40 based on the reception of the security tag detection signal. The security tag alarms 615 and 616 display the security tag detection order (for example, 1st, 2nd,...). As a result, the store clerk can appropriately determine the processing order of the degaussing confirmation even when the activated security tag is detected in the plurality of self-checkout terminal devices 40.

  [Step S86] The monitoring terminal apparatus 50 waits for confirmation of degaussing and proceeds to step S87. The demagnetization confirmation is performed, for example, by receiving a touch (input) of a button display of the security tag alarm 615 or the security tag alarm 616 by a store clerk.

  [Step S87] The monitoring terminal device 50 determines whether or not a security tag non-detection signal has been received from the self-checkout terminal device 40 to be monitored. When the security tag non-detection signal is received from the self-checkout terminal device 40 to be monitored, the monitoring terminal device 50 proceeds to step S88. When the security tag detection signal is not received, the monitoring terminal device 50 receives the security tag non-detection signal. Wait for reception.

[Step S88] The monitoring terminal device 50 transmits a barcode scan permission signal to the self-checkout terminal device 40 to be monitored.
[Step S89] The monitoring terminal device 50 deletes the button display (alarm information display) of the security tag alarm 615 or the security tag alarm 616. Moreover, the monitoring terminal device 50 updates the security tag detection order when the activated security tag is detected in the plurality of self-checkout terminal devices 40.

[Step S90] The monitoring terminal device 50 proceeds to Step S81 when the end condition is not satisfied, and ends the product registration confirmation process when the end condition is satisfied.
In this way, since the store clerk can know that the customer has failed to demagnetize the security tag, the self-checkout system 3 can reduce the possibility that the customer will feel uncomfortable and can operate the security system. To do. In addition, according to such a self-checkout system 3, even if there is detection of an activated security tag in a plurality of self-checkout terminal devices 40, the store clerk can respond efficiently.

  Next, a fourth embodiment in which the operation of the self-checkout terminal device is restricted by an instruction from the monitoring terminal device 50 will be described with reference to FIG. FIG. 16 is a flowchart of merchandise registration confirmation processing executed by the monitoring terminal device of the fourth embodiment.

  In the fourth embodiment, the monitoring terminal device 50 issues different instructions for the self-checkout terminal device 40 that is a demagnetization confirmation target and the self-checkout terminal device 40 that is not a demagnetization confirmation target with respect to restrictions on the acquisition of product information. This is different from the above-described embodiment.

  This is because the store clerk cannot perform degaussing confirmation for a plurality of self-checkout terminal devices 40 at the same time, and therefore, a self-checkout terminal device 40 that is a degaussing confirmation target and a self-checkout terminal device 40 that is not a degaussing confirmation target. This is to make the response different.

  Note that steps S81 to S85 of the product registration confirmation process of the fourth embodiment are the same as the product registration confirmation process of the third embodiment, and therefore the same reference numerals are used and description thereof is omitted.

  [Step S91] The monitoring terminal device 50 determines whether or not the self-checkout terminal device 40 to be monitored is a priority degaussing confirmation target. The determination as to whether or not the self-checkout terminal device 40 is a priority degaussing confirmation target can be made, for example, based on whether or not the activated security tag detection order in the plurality of self-checkout terminal devices 40 is first. . Alternatively, the determination as to whether or not the self-checkout terminal device 40 is a priority degaussing confirmation target can be made based on a selection operation of a priority degaussing confirmation target by a store clerk operating the monitoring terminal device 50.

  When the monitored self-checkout terminal device 40 is not the priority degaussing confirmation target, the monitoring terminal device 50 proceeds to step S92. On the other hand, when the self-checkout terminal device 40 to be monitored is the priority degaussing confirmation target, the monitoring terminal device 50 proceeds to step S94.

  [Step S92] The monitoring terminal device 50 waits for a provisional confirmation and proceeds to step S93. The provisional confirmation is performed, for example, by inputting the provisional confirmation to be operated when the store clerk cannot confirm the demagnetization (during other self-checkout terminal device 40 is responding). Alternatively, the provisional confirmation can be automatically performed when a predetermined condition is satisfied, such as waiting for reception of a security tag non-detection signal after the other self-checkout terminal device 40 confirms demagnetization.

  [Step S93] The monitoring terminal device 50 transmits a barcode scan permission signal and a settlement non-permission signal to the self-checkout terminal device 40 to be monitored. As a result, the customer is allowed to register the product, but cannot perform the checkout process. During the waiting time for the clerk to confirm demagnetization, the customer can continue the product registration. However, since the customer cannot settle the registered product, the activated state of the security tag is detected by the security gate, and the customer does not feel uncomfortable. In addition, since the customer can continue the product registration before confirming degaussing, it is possible to shorten the time that the clerk is aware of as a waiting time until confirmation of demagnetization.

The monitoring terminal device 50 proceeds to step S81 after transmitting the barcode scan permission signal and the settlement non-permission signal to the self-checkout terminal device 40 to be monitored.
[Step S94] The monitoring terminal device 50 waits for confirmation of demagnetization and proceeds to step S95.

  [Step S95] The monitoring terminal device 50 determines whether or not a security tag non-detection signal has been received from the self-checkout terminal device 40 to be monitored. When the security tag non-detection signal is received from the self-checkout terminal device 40 to be monitored, the monitoring terminal device 50 proceeds to step S96. When the security tag detection signal is not received, the monitoring terminal device 50 receives the security tag non-detection signal. Wait for reception.

  [Step S96] The monitoring terminal device 50 transmits a barcode scan permission signal to the monitored self-checkout terminal device 40. In addition, when the monitoring terminal device 50 has transmitted the payment non-permission signal to the self-checkout terminal device 40 to be monitored, the monitoring terminal device 50 also transmits the payment permission signal.

  [Step S97] The monitoring terminal device 50 deletes the button display (alarm information display) of the security tag alarm 615 or the security tag alarm 616. Moreover, the monitoring terminal device 50 updates the security tag detection order when the activated security tag is detected in the plurality of self-checkout terminal devices 40.

[Step S98] If the end condition is not satisfied, the monitoring terminal apparatus 50 proceeds to step S81. If the end condition is satisfied, the monitoring terminal apparatus 50 ends the product registration confirmation process.
In this way, since the store clerk can know that the customer has failed to demagnetize the security tag, the self-checkout system 3 can reduce the possibility that the customer will feel uncomfortable and can operate the security system. To do. In addition, according to such a self-checkout system 3, even if there is detection of an activated security tag in a plurality of self-checkout terminal devices 40, the store clerk can respond efficiently. Moreover, the customer can reduce the waiting time for degaussing confirmation.

  The monitoring terminal device 50 disallows barcode scanning when the self-checkout terminal device 40 to be monitored becomes a degaussing confirmation target, but instead of restricting barcode scanning, it restricts product registration. And so on.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the self-checkout terminal device and the monitoring terminal device should have is provided.
