Shopping cart and cash register system

Technical field

[0001] The present invention relates to a purchased product storage cart for storing and transporting a product to be purchased by a customer in a store in various distribution businesses such as a mass merchandise store, a convenience store, and a supermarket. The present invention relates to a register system using a storage cart. Background art

[0002] For example, when purchasing products at stores in various distribution businesses such as a mass retailer, a convenience store, and a supermarket, in general, a customer wants to purchase in a predetermined cart such as a shopping cart or a shopping cart. Stores goods to be transported inside the store, and heads to the register at the stage of performing payment. The payment is made by directly entering the price of the product stored in the operator's power for operating the register, or if the register is equipped with a so-called POS (Point Of Sale) system, This is done by reading the attached bar code.

[0003] On the other hand, there has been proposed a technology in which a cart is provided with a scanner for reading a barcode attached to a product for the purpose of reducing register operation processing by an operator and reducing settlement time. (See, for example, Patent Document 1.) o

Patent Document 1: JP-A-5-81559

[0005] Specifically, Patent Literature 1 discloses a wireless registration terminal for registering a customer to purchase a product, a shopping cart loaded with the wireless registration terminal, and a checkout POS terminal operated by an operator. A POS system comprising a controller having wireless receiving means for receiving product information from a wireless registration terminal and storage means for storing the product information received by the wireless receiving means is disclosed. In particular, this POS system has an identification display on the shopping cart and an identification means for reading the identification display of the shopping cart on the checkout POS terminal. As a result, in this POS system, since the identification display of the shopping cart can be automatically input, the operation by the operator can be made unnecessary. [0006] In this type of field, it is important to prevent fraudulent acts such as shoplifting as operators become unmanned. For example, a technique described in Patent Document 2 has been proposed. .

Patent Document 2: JP-A-7-141569

[0008] Specifically, Patent Document 2 discloses a product code reading unit for reading a product code attached to a product, and a storage for storing the product whose product code is read by the product code reading unit. And a POS system including a management unit that manages the purchased product storage / transport device having a self-scanning function and a management unit for the purchased product storage / transport device. In particular, in these purchased merchandise storage and transport devices and POS systems, the purchased merchandise storage and transport device includes a weighing device that measures the total weight of the goods stored in the storage portion and a weighing device in the storage portion that is weighed by the weighing device. A weighing determination unit that determines a change in the total weight of the product; and an alarm that generates an alarm when the weighing determination unit determines that the total weight of the product in the storage unit has increased without reading the product code. And a generator. As a result, the purchase goods storage and transport device and POS system can prevent fraudulent acts in which customers take out goods without intentionally or negligibly reading product codes.

[0009] By the way, in recent years, the ratio of personnel expenses to store costs has tended to be extremely large, and in view of the current situation in which the waiting time at the register when making payments has become long, the above-mentioned situation has been taken into account. The importance of a system having a self-scan function including the techniques disclosed in Patent Documents 1 and 2 and the like is increasing steadily. Under such circumstances, it is important to take measures to prevent fraudulent acts such as shoplifting.

[0010] Here, the technology described in Patent Document 2 described above is provided with a weighing function in a cart, and determines the presence or absence of fraud based on a change in the total weight of the products stored in the cart. . However, in the case of powerful technology, depending on the type of wrongdoing, the presence or absence of the wrongdoing cannot be determined in some cases.

[0011] Fraud is roughly classified into two types.

[0012] As a first fraud, there is a case where a product is stored in a cart without reading a product code. In the meantime, this case was described in Patent Document 2 mentioned above. It can be prevented by technology.

[0013] Further, as a second fraudulent act, a case may be considered in which a merchandise whose code has been read is not stored in a cart, but another product of the same weight is stored. In other words, this case is an act of substituting another product that is substantially more expensive than the product whose product code has been read. Such an act was not able to be prevented by the conventional technology for determining the presence or absence of fraud based on the change in the total weight of the goods stored in the cart.

[0057] Such a purchased product storage cart 10 is carried by the customer who wants to purchase the product GD, is transported in the store, and is controlled by the CPU 51, through the communication unit 57, through the register 20 and Z or Z or Communication is performed with the management server in the management center 30, and the payment process is performed while the product GD is stored in the storage unit 11.

At this time, the purchased product storage cart 10 is stored in the storage unit 11 without reading the barcode information by the barcode reader 52, and when the total weight of the product GD increases, Under control, it is determined that there has been fraudulent activity, and the Is displayed, and a predetermined alarm is output via the speaker 56. Further, when the total weight of the goods GD stored in the storage unit 11 is reduced by the same weight as the increased weight, the purchased goods storage cart 10 is controlled under the control of the CPU 51. Is determined to have been returned by the customer, the fact is displayed on the display unit 54, and the output of the alarm output via the speed 56 is stopped. In addition, the purchased goods storage cart 10 executes a filter function for discriminating, under the control of the CPU 51, when an unexpected load is applied to the weighing machine 53 due to negligence such as playing with an infant. However, careless alarm output and the like can be avoided.

When the barcode information cannot be read by the barcode reader 52, the shopping cart 10 displays the fact on the display unit 54 under the control of the CPU 51. A predetermined message is output via the speaker 56. If the barcode information cannot be read even after performing this reading operation three times, for example, the purchased merchandise receiving cart 10 waits under the control of the CPU 51 to support the customer. Notifying the calling operator via the communication unit 57, and transmitting a call signal for calling the operator and notifying the location of the customer and the reason for the call, and the display unit A message prompting the customer to wait until an instruction from the operator is displayed at 54 is displayed, and a predetermined message is output via the speaker 56. In this case, when the operator inputs information specific to the product GD via the operation unit 55, the purchased product storage cart 10 transits to the same state as when the barcode information is read by the barcode reader 52. Then, under the control of the CPU 51, the barcode information of the product GD can be stored in the storage unit 58. In the register system, the only operation that the operator operates at the store is the powerful interrupt processing. In addition, the purchased product storage unit 10 receives the enable signal transmitted from the management center in the management center 30 through the communication unit 57 under the control of the CPU 51 without using the operation of the operator. Alternatively, based on this enable signal, the barcode reader 52 may transit to the same state as the state where the barcode information is read.

Next, the register 20 will be described.

[0061] The register 20 is used to settle the goods GD stored in the purchased goods storage cart 10. It is installed in stores and has a so-called POS (Point Of Sale) system.

The register 20 is roughly divided into a register main body 21 that performs various kinds of processing, and a transport mechanism 22 that transports the purchase product storage cart 10 to be settled.

As shown in FIG. 4, such a register 20 includes, as shown in FIG. 4, a CPU 101 that controls each unit in a comprehensive manner, and a card reader 102 that reads a predetermined payment card for performing settlement. A payment request detection unit 103 for detecting a request to start a payment process from the shopping cart 10; a payment unit 104 for performing a payment process using a payment card read by the card reader 102; , A center communication unit 106 for communicating with the management server in the management center 30, a display unit 107 for displaying various information such as purchase details, and various voices. It has a speaker 108 for outputting, a printing unit 109 for printing a receipt, a storage unit 110 for storing various information, and a card writer 111 for writing a new balance on a payment card.

[0064] The CPU 101 executes predetermined software to control each unit as a whole and execute various processes.

[0065] The card reader 102 reads the card by inserting an arbitrary payment card possessed by the customer in order to perform a payment such as a prepaid card or a credit card when the customer performs the payment. The card information read by the card reader 102 is supplied to the settlement unit 104, and a settlement process is performed.

[0066] When the purchased merchandise storage cart 10 is placed on the transport mechanism 22, the payment request detection unit 103 detects this and determines that the start of the payment processing has been requested. When it is determined that the start of the payment process has been requested, the payment request detection unit 103 outputs the list of the barcode information stored in the storage unit 58 described above to the purchased product storage cart 10. The request signal is transmitted via the local communication unit 105.

[0077] When the customer who wants to purchase the product GD places the purchased product storage cart 10 on the transport mechanism 22 and detects this by the checkout request detection unit 103, the register 20 controls the CPU 101. Based on the received list, the settlement amount is calculated and the purchase details are displayed on the display screen of the display unit 107. I do. Register 20 then determines that the customer has The payment process is performed by inserting the payment card, a receipt is issued in response to this, and a series of payment processing is completed.

[0078] At this time, the register 20 outputs a predetermined guidance message via the speed 108 under the control of the CPU 101 under the control of the CPU 101 when performing the payment processing, thereby allowing the payment card to be transmitted to the customer. The user is prompted to insert the payment card into the card reader 102.If the remaining amount of the payment card is insufficient, the user is prompted to use another payment card.If the user does not have another payment card, a new payment card is required. By prompting the purchase of a payment card, the payment process can be performed reliably and smoothly.

Finally, the management center 30 will be described.

[0080] The management center 30 is a facility that manages the purchased goods storage cart 10 and the register 20 provided in each store. As shown in FIG. 6, the management center 30 has at least one management server 150 and at least one control console 160 in terms of hardware. In the figure, the two management servers 150, 150 are connected to each other, and

A part 156.

[0082] The CPU 151 executes predetermined software to control each unit in an integrated manner and executes various processes.

The communication unit 152 performs a predetermined wireless communication with the center communication unit 106 in the register 20 under the control of the CPU 151. Specifically, the communication unit 152 receives the call signal for calling the operator transmitted via the communication unit 57 in the purchased product storage cart 10 via the center communication unit 106 in the register 20. Further, the communication unit 152 receives information indicating the content of the receipt issued by the register 20. Further, the communication unit 152 is a product database in which at least the product name, the price, and the product code are associated with each other. When rewriting, the data for update is transmitted to all the purchased carts 10 and the registers 20 in synchronization with each other. Further, when the monitoring unit 153 detects a fraudulent activity by the customer, the communication unit 152 transmits information indicating the fraud to the purchase product storage cart 10 via the center communication unit 106 in the register 20. Send to

The monitoring unit 153 is provided to monitor the inside of a store, and acquires an image captured by a monitoring camera system provided in the store under the control of the CPU 151. Under the control of the CPU 151, the monitoring unit 153 performs a predetermined analysis on the image captured by the monitoring camera system to read a fraudulent activity that could not be prevented conventionally, that is, a product code. It is also possible to detect an action of storing a product instead of storing it in the storage unit 11 and replacing it with another product of the same weight. The surveillance camera system will be described later.

The interface unit 154 connects to another management server and a control console. Specifically, when issued by the control signal CPU 151 for controlling the control console, the interface unit 154 transmits the control signal to each control console, and also transmits various signals transmitted from each control console. Receive the signal.

[0086] The storage unit 155 stores, under the control of the CPU 151, various types of information including information on controllable control consoles and the like.

[0087] The database unit 156 stores various databases such as the above-mentioned product database in which at least a product name, a price, and a product code are associated with each other, and a customer database indicating customer attributes and the like. Various databases stored in the database unit 156 can be arbitrarily rewritten, Z-read, or read under the control of the CPU 151.

The management server 150 composed of such hardware is configured as shown in FIG.

[0089] That is, as shown in the figure, the management server 150 includes a management control unit 171 that comprehensively manages and controls each function, and a predetermined control when an operator is called from the purchased product storage cart 10. A local call processing unit 172 for performing a predetermined process; a register call processing unit 173 for performing a predetermined process when an operator is called from the register 20; A database load access processing unit 174 that accesses the database unit 156 to load data for updating when updating the database stored in the shopping cart and Z or the register 20 and the database load access A buffer unit 175 for temporarily storing data acquired by the processing unit 174; a consistency determining unit 176 for determining consistency of data temporarily stored in the buffer unit 175; and a consistency determining unit 176 and a database update access processing unit] _ ₇ 7 to access the database unit 156 when it is determined that there is consistent with.

The management server 150 manages and controls the control console 160 corresponding to each store as a base of the POS system, and manages and controls the purchased goods storage cart 10 and the register 20 provided in each store. I do.

On the other hand, the control console 160 includes a CPU 161 that controls the entire components, a communication unit 162 that communicates with the management server 150, a display unit 163 that displays various types of information, and an operation performed by the administrator. It has an operation unit 164 having various function buttons, an alarm unit 165 for generating an alarm when there is a call from a customer or a wrongdoing by the customer, and a storage unit 166 for storing various information.

[0092] By executing predetermined software, the CPU 161 controls each unit as a whole and executes various processes.

The communication unit 162 performs predetermined wireless communication with the management server 150 under the control of the CPU 161. Specifically, the communication unit 162 transmits information input via the operation unit 164 to the management server 150. In addition, the communication unit 162 receives the in-store image acquired by the management server 150.

[0094] The display unit 163 is, for example, an LCD or the like, and under the control of the CPU 161, the management server 15

The in-store image transmitted from 0 is displayed on the display screen. The administrator can monitor the inside of the store by visually recognizing the image displayed on the display unit 163.

The operation unit 164 performs various input operation devices such as a keyboard, a button, and a joystick, and inputs various information necessary for management.

[0096] The alarm unit 165 outputs a predetermined alarm that informs the administrator of the improper behavior of the customer when the management server 150 detects the fraud. [0097] The storage unit 166 stores various information including information on customers under the control of the CPU 161. .

[0098] The control console 160 manages and controls the purchased goods storage cart 10 and the register 20 provided in the assigned store while being managed and controlled by the management server 150.

[0099] Now, in a register system including such a purchased product storage cart 10, the register 20, and the management center 30, the product GD by the customer is processed through a series of steps as shown in Figs. Is made.

[0100] First, in the register system, as shown in Fig. 8, in step S1, when a customer who owns a purchased product storage cart 10 stores a desired product GD in the storage section 11, the customer GD is attached to the product GD. The read barcode is read by the barcode reader 52, and in step S2, the weight of the product GD is measured by the weighing device 53.

[0101] Then, in step S3, the shopping cart 10 stores the weight information included in the barcode information read by the barcode reader 52 and the weight information weighed by the scale 53 by the CPU 51 in step S3. By comparison, it is determined whether these weight information matches.

[0102] Here, when the purchased product storage cart 10 determines that the weight information does not match, for example, an improper act of storing the product GD without reading the product code in the storage unit 11 has occurred. In step S4, a predetermined alarm is output via the speed 56 under the control of the CPU 51. However, it is possible that this alarm is output simply due to erroneous operation. Therefore, in step S5, which is a step to avoid mistakes caused by such an erroneous operation, in the case of an erroneous operation, in step S6, the customer stops the alarm via the operation unit 55. By doing so, the output of the alarm is stopped, and the processing from step S1 is repeated. Further, when it is determined that the weight information does not match, the purchased product storage cart 10 may perform a predetermined process for discharging the product GD from the storage unit 11!

[0103] On the other hand, when it is determined that the weight information matches, the purchased product storage cart 10 stores the barcode information on the product GD under the control of the CPU 51 as the above list. 58, and the name of the product GD, etc. Display screen, and the process proceeds to step S7. This step S7 is a fraudulent act that could not be prevented in the past, that is, an act of storing a product whose product code has been read and replacing it with another product of the same weight without storing it in the storage unit 11. It is provided to detect. That is, in step S7, when the management server 150 in the management center 30 detects the fraudulent activity using the surveillance camera system provided in the store in step S7, the shopping cart 10 stores information indicating that fact. It receives the communication via the communication unit 57 and performs the processing of steps S4 to S6.

As described above, this fraud detection is performed by performing a predetermined analysis on the image captured by the monitoring camera system provided in the store by the monitoring unit 153 in the management server 150. be able to. Here, a powerful surveillance camera system will be described.

[0105] This surveillance camera system analyzes images captured by a commercially available surveillance camera, and differs from a conventional surveillance camera system that simply captures and displays an image. is there. This surveillance camera system has a function of determining a point to be monitored in advance, "marking the surveillance point", "capturing a change", and "automatically tracking".

More specifically, this surveillance camera system marks a predetermined point with a so-called swing camera having a zoom function, and when the movement of a moving object such as a person is detected at the point, zooms in on the point. In addition, an image is captured and recorded on a predetermined management server, and is automatically tracked in accordance with the movement of the moving object. The detection of the motion can be performed by using any method, for example, by taking the difference between images captured continuously.

. In addition, the surveillance camera system obtains a predetermined number of still images or moving images for a predetermined time from the management server and transmits the obtained images to a predetermined terminal such as a mobile phone from the management server. In addition, it has a function of transmitting the still image or moving image via a network such as the Internet, and sending a mail to that effect to notify a remote administrator.

[0107] The surveillance camera system can also monitor in a dark place by using an infrared-type swing camera as the surveillance camera. [0108] When an illegal movement of the customer is detected based on the image captured by such a surveillance camera system, the purchased product storage cart 10 receives information indicating the detection via the communication unit 57. . As described above, the purchased product storage cart 10 performs all the assumed operations by performing the determinations shown in steps S3 and S4 in conjunction with the management server 150 that analyzes the images captured by the surveillance camera system. It is possible to prevent fraudulent acts. At this time, the purchased product storage cart 10 receives, via the communication unit 57, the fixed voice or the voice of the operator transmitted from the management server 150 that has detected the fraudulent activity, instead of outputting an alarm via the speaker 56. Alternatively, the sound may be output via the speaker 56.

[0109] If the fraudulent activity is not detected, the purchased product storage cart 10 shifts the process to step S8 and stores the product in the storage unit 11 by the measuring device 53! By detecting a change in the total weight, the CPU 51 determines whether or not a certain product GD stored in the storage unit 11 has been returned by the customer. That is, this step S8 is to take a countermeasure in the case where the user decides not to purchase the product GD stored in the storage unit 11 for purchase.

[0110] When it is determined that the product GD stored in the storage unit 11 has not been returned by the customer, the purchased product storage cart 10 proceeds to step S10, while the processing proceeds to step S10. If it is determined that the product GD stored in the storage unit 58 has been returned by the customer, the barcode information on the product GD is deleted from the list stored in the storage unit 58 in step S9, and the process proceeds to step S10. And transfer processing. At this time, the purchased merchandise cart 10 may display the name of the returned merchandise GD on the display screen of the display unit 54 under the control of the CPU 51, if necessary.

[0111] The purchased product storage cart 10 repeats the processing of steps S1 to S9 described above until all the products GD to be purchased are stored in the storage unit 11, and requests to purchase in step S10. When all the products GD to be stored are stored in the storage unit 11, the process shifts to a settlement process shown in FIG.

In the cash register system, when performing the settlement process, as shown in FIG. 9, in step S 11, the customer places the purchased goods storage cart 10 in the transport mechanism 25 in the cash register 20. When the settlement request detecting unit 103 in the register 20 detects that the settlement is performed in Step S12, the settlement process is started.

[0113] In response to this, in step S13, the register 20 drives the transport mechanism 22 to transport the purchased product storage cart 10 to a predetermined location, and in step S14, the purchase It communicates with the communication unit 57 of the product storage cart 10 and receives a list of the products GD stored in the storage unit 11 of the purchased product storage cart 10.

[0114] Subsequently, the register 20 calculates the settlement amount by the CPU 101 based on the list received via the local communication unit 105 in step S15, and displays the display screen of the display unit 107 in step S16. Display various information such as purchase details.

[0115] Then, in step S17, the register 20 reads the payment card possessed by the customer, which has confirmed the information displayed on the display screen of the display unit 107, with the card reader 102, thereby performing the payment processing using the payment card. When this settlement processing is completed, in step S18, a receipt is issued by the printing unit 109, and a series of processing ends.

As described above, in the register system, the bar code reader 52 and the weighing device 53 are provided in the purchased merchandise storage cart 10, and the images captured by the purchased merchandise storage cart 10 and the surveillance camera system are analyzed. By linking with the management server 150, not only the illegal operation of storing the product in the storage unit 11 without reading the product code by the bar code reader 52, but also the product reading the product code by the bar code reader 52 can be performed. It is also possible to prevent fraudulent acts of replacing the product with another product of the same weight without storing it in the storage section 11.

[0117] It is needless to say that the weighing device 53 in the purchased product storage cart 10 needs a compensation function to maintain a predetermined accuracy. In particular, there is so-called background noise, and it is important to remove it. However, since the purchased product storage cart 10 is provided with the barcode reader 52 together with the weighing device 53 and works in conjunction with each other, it is possible to remove background noise without providing expensive filtering means. In the cash register system, the bar code reader 52 and the weighing device 53 are provided in the shopping cart 10 so that an operator who operates the cash register 20 becomes unnecessary, thereby reducing the settlement time and labor cost. It goes without saying that it can be done.

[0119] The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, after the settlement processing is completed, no description is given.However, the present invention describes that the commodity GD is taken out from the storage unit 11 of the purchased commodity storage cart 10 and transported. For ease, a predetermined automatic packing means for automatically packing the merchandise GD stored in the storage section 11 may be provided in the purchased merchandise storage cart 10.

[0120] Further, in the above-described embodiment, the description has been made assuming that the settlement process is performed using the payment card by the card reader 102. Payment processing using a terminal may be performed.

[0121] Furthermore, according to the present invention, by using a weighing device 53 in the purchased product storage cart 10 that performs pseudo-sensing by a so-called AI (Artificial Intelligence) function, it is possible to detect fraudulent activity with higher accuracy. It becomes possible.

[0122] Furthermore, in the above-described embodiment, by preventing the purchase merchandise storage cart 10 from interlocking with the management server 150 that analyzes the image captured by the surveillance camera system provided in the store, the conventional prevention is achieved. Although it has been described as detecting fraudulent activities that were impossible to perform, the present invention introduces a so-called RFID (Radio Frequency Identification) mechanism, in which an IC (Integrated Circuit) chip is used instead of a barcode. The tag may be attached to the product as a medium to detect the fraud.

[0123] Hereinafter, such a register system will be briefly described.

[0124] That is, in a register system incorporating this RFID mechanism, instead of the barcode reader 52 in the purchased product storage cart 10, at least a product code for identifying the product and a A function to communicate with a tag that records information indicating weight and has a communication function is provided.

[0125] Then, in step S1 shown in FIG. 8, when the customer stores the product in the storage unit 11, the purchased product storage cart 10 communicates with the tag attached to the product. By doing so, the product code and the information indicating the weight of the product are read, and at step S2 In step S3, the weight of the product is weighed by the weighing device 53, and in step S3, the CPU 51 compares the weight information obtained by communicating with the tag with the weight information weighed by the weighing device 53. By judging whether the information has the same strength or not, fraudulent acts of storing the product in the storage unit 11 without reading the product code are detected.

[0126] On the other hand, the purchased product storage cart 10 is designed to detect fraudulent misconduct in which the product whose code is read is not stored in the storage unit 11 but is replaced with another product of the same weight and stored. By performing communication with the tags attached to all the products stored in the storage unit 11 at time intervals, the switching of the products is detected. That is, the purchased product storage cart 10 compares the information read and stored in the storage unit 58 when the product is first stored in the storage unit 11 and the information read after a predetermined time by the CPU 51, and the CPU 51 compares these information. By judging whether or not they match, it detects a fraudulent act of not storing the product whose product code is read in the storage unit 11 but replacing it with another product of the same weight and storing it.

[0127] As described above, in the register system, by introducing the RFID mechanism, it is possible to detect fraudulent acts with high accuracy while reducing the cost without having to provide a separate surveillance camera system. . In addition, in this register system, when the customer stores a product in the storage section 11 of the purchased product storage cart 10, it is not necessary to perform an operation of forcing a barcode on the barcode reader 52. Erroneous operation due to forgetting can be eliminated, and extremely high convenience can be provided to customers.

[0128] Of course, in a register system, a barcode and an RFID can be combined, thereby realizing an extremely excellent system that cannot be assumed conventionally.

[0129] As described above, it goes without saying that the present invention can be appropriately changed without departing from the spirit of the present invention.
