MONITORING ITEM MISMATCHES DURING CHECKOUTS IN STORES AND PREVENTING LOSSES DUE TO THE ITEM MISMATCHES

Abstract
A computer-implemented method, computer program product, and computer system for preventing losses due to mismatches during checkouts in a store. The computer system causes one or more sensors to capture one or more attributes of an item being checked out by a customer. The computer system matches the captured one or more attributes to one or more attributes corresponding to one of a barcode scanned, a number keyed in, and an item name chosen by the customer. The computer system pauses a checkout process, in response to a mismatch. The computer system calculates a difference between a price corresponding to one of the barcode, the number, and the item name and an actual price of the item. The computer system, in response to determining a significant loss occurring to the store, notifies the store to correct the mismatch and processes a transaction of the item at the actual price.
Description
BACKGROUND

The present invention relates generally to analyzing data of checkouts in stores, and more particularly to using analysis of data of checkouts to monitor item mismatches during checkouts in stores and prevent losses due to the item mismatches.


Attaching barcode stickers to grocery items, such as individual fruits, deli boxes, and soft drinks, is a commonly used method to associate a price with each item. In many stores, shoppers can scan each item at the time of payment and pay for the entire set of items. In certain situations, an item may not be associated with a barcode, and a shopper needs to type its associated code directly or select an item picture using a terminal of a checkout lane in a store. In a store, a shopper may mistakenly type a wrong code for an item and may result in a significantly low or high price for the item, which may cause a loss to either the store or the shopper.


SUMMARY

In one aspect, a computer-implemented method for preventing losses due to item mismatches during checkouts in a store is provided. The method includes causing one or more sensors to capture one or more attributes of an item being checked out by a customer. The method further includes matching the one or more attributes captured by the one or more sensors to one or more attributes stored in a database, where the one or more attributes stored in the database is corresponding to one of a barcode scanned by the customer, a number keyed in by the customer, and an item name chosen by the customer. The method further includes, in response to a mismatch, pausing a checkout process of the item. The method further includes calculating a difference between a price corresponding to one of the barcode, the number, and the item name and an actual price of the item. The method further includes, in response to determining a loss occurring to the store, determining whether the difference is greater than a predetermined number of standard deviations of a normal distribution of prices of the item, where the normal distribution is based on historical data of the prices of the item. The method further includes, in response to determining the difference being greater than the predetermined number of standard deviations, notifying the store to correct the mismatch. The method further includes, in response to the mismatch being corrected, processing a transaction of the item at the actual price of the item.

DETAILED DESCRIPTION

Embodiments of the present invention provide a solution to errors due to item mismatches during checkouts in stores. In embodiments of the present invention, a system monitors item mismatches during checkouts and prevents losses due to the mismatches. In embodiments of the present invention, a system analyzes data of checkouts. The system disclosed in the present invention improves the quality of the data, which can prevent losses, customer dissatisfaction, and overall drop of a store's image.



FIG. 1 is a systematic diagram illustrating system 100 for monitoring item mismatches during checkouts and preventing losses due to item mismatches, in accordance with one embodiment of the present invention. System 100 includes system 110 for analyzing data of checkouts. In the embodiment shown in FIG. 1, system 110 for analyzing data of checkouts is situated on a computing device or a server. A computing device or server is described in more detail in later paragraphs with reference to FIG. 3. System 110 for analyzing data of checkouts is connected to checkout device 130 in store 160; the connection between system 110 and checkout device 130 is through network 120.


Network 120 can be any combination of connections and protocols which support communications among the local devices and the central server. For example, the network may be the Internet which represents a worldwide collection of networks and gateways to support communications between devices connected to the Internet; the network may be implemented as an intranet, a local area network (LAN), a wide area network (WAN), and a wireless network.


Checkout device 130 is equipped with a variety of sensors to identify one or more attributes of an item. The sensors may be capable of capturing dimensions (e.g., a sonar to assess height, a scale to assess weight). The sensors may also be capable of capturing other attributes such as temperature and texture. The sensors may be imaging devices, for example cameras, which are capable of capturing images of an item. System 110 causes the sensors to capture one or more attributes of items that are scanned at checkout device 130, during a checkout of customer 140. System 110 may cause one or more imaging devices to capture one or more images. System 110 also causes the sensors to monitor actions of the customer while customer 140 checks out the items.


In one embodiment, system 110 matches the one or more attributes captured by the sensors to the one or more attributes stored in a database, where the one or more attributes stored in the database are corresponding to barcodes scanned by customer 140, numbers keyed in by customer 140, or an item name chosen by customer 140 at checkout device 130. In another embodiment, system 110 matches the one or more images captured by the imaging devices to one or more images stored in a database, where images stored in the database are corresponding to barcodes scanned by customer 140, numbers keyed in by customer 140, or an item name chosen by customer 140 at checkout device 130. In one embodiment, system 110 determines whether there are mismatches between the one or more attributes captured and the one or more attributes stored in the database. In another embodiment, system 110 determines whether there are mismatches between the one or more images captured and the one or more images stored in the database. In response to determining that there is a mismatch of an item, system 110 pauses a transaction of the item; further, system 110 calculates losses due to the mismatch, by calculating a difference between a price corresponding to the barcode, the number, or the item name and an actual price of the item. System 110 retrieves from the database the price corresponding to the barcode, the number, or the item name. The actual price of the item is a price corresponding to the one or more attributes captured by the one or more sensors or the one or more images captured by the one or more imaging devices. System 110 retrieves from the database the actual price.


If the price corresponding to the barcode, the number, or the item name is less than the actual price of the item, there will be a loss to store 160. In response to determining that there is a loss to store 160, system 110 determines whether a correction action is needed by personnel 150 of store 160. For determining whether the correction action is needed, system 110 determines whether the loss is greater than a predetermined number of standard deviations of a normal distribution of prices of an item, where the normal distribution is based on historical data of the prices of the item and the historical data is stored in the database. If the loss is greater than a predetermined number of standard deviations (e.g., one standard deviation), the correction action is needed; otherwise, no action is needed.


If the correction action is needed, system 110 notifies personnel 150 to correct the item mismatch before processing a transaction of the item. System 110 sends the notifications to personnel 150; for example, system 110 sends the notifications to a mobile device of personnel 150 through network 120. System 110 may also send the notifications to personnel 150 through checkout device 130. If the correction action is not needed, system 110 will process a transaction of the item at a price based on the scanned barcodes, the keyed-in numbers, or the customer chosen item name, and then system 110 notifies customer 140 that the transaction is a favorable deal to customer 140 (with a loss to store 160). For example, system 110 may send the notifications to customer 140 through checkout device 130 and/or indicate on a receipt the savings to customer 140.


If the price corresponding to the scanned barcode, the keyed-in number, or the customer chosen item name is greater than the actual price of the item, there will be a loss to customer 140. In response to determining that there is a loss to customer 140, system 110 notifies personnel 150 to correct the item mismatch and then process a transaction of the item at an actual price.


After processing transactions of items with mismatches, system 110 analyzes the mismatches. System 110 stores information of the mismatches in the database for future transactions of the same items. The database may be part of system 110; the database may also be a separate entity in system 100. The information stored in the database is used by system 110 to identify the mismatches and calculate the losses.


In another embodiment, system 110 may be implemented in a cloud computing environment. The cloud computing environment is described in more detail in later paragraphs with reference to FIG. 4 and FIG. 5. In yet another embodiment, system 110 may be situated on a computer device or server in store 160, which may be connected to another computer device or server in network 120 or in cloud. In yet another embodiment, system 110 may be embedded into checkout device 130.



FIG. 2(A) and FIG. 2(B) present a flowchart showing operational steps of monitoring item mismatches during checkouts and preventing losses due to mismatches, in accordance with one embodiment of the present invention. In the example shown in FIG. 1, the operational steps are implemented by system 110 for analyzing data of checkouts, where system 110 is situated on a computing device or server.


Referring to FIG. 2(A), at step 201, the computing device or server identifies a store. The computing device or server analyzes the contextual environment where a customer is located, for example, a grocery store or a supermarket. At step 202, the computing device or server identifies a geographical location of the store. For example, the computing device or server is aware of the geographical location of the grocery store or the supermarket. At step 203, the computing device or server identifies a checkout lane of the customer in the store. Through the checkout lane (e.g., self-checkout lane), the customer checks out items purchased in the store. For example, the computing device or server is aware of the checkout lane when the customer approaches the checkout lane or scans a shopper card.


Further referring to FIG. 2(A), at step 204, the computing device or server causes one or more sensors to capture one or more attributes of an item being checked out. For example, a checkout device at checkout lane is equipped with the one or more sensors. For example, the one or more attributes may include but not limited to dimensions, weight, temperature, and texture. In another embodiment, the computing device or server causes one or more imaging devices to capture one or more images of an item being checked out.


At step 205, the computing device or server causes the one or more sensors to monitor actions of the customer while the customer checks out the item. Machine learning capabilities of the computing device or server identifies the shopper's actions; for example, the computing device or server identifies whether the customer is scanning the item or weighting the item.


Further referring to FIG. 2(A), at step 206, the computing device or server matches the one or more attributes captured by the one or more sensors to one or more attributes stored in a database, where the one or more attributes stored in the database is corresponding to one of a barcode scanned by the customer, a number keyed in by the customer, and an item name chosen by the customer. In another embodiment, the computing device or server matches the one or more images captured by the one or more imaging devices to one or more images stored in a database, where the one or more images stored in the database is corresponding to one of a barcode scanned by the customer, a number keyed in by the customer, and an item name chosen by the customer. The attributes or images for the expected barcode, number, or item name have been established within in the database. At step 206, the computing device or server identifies a situation in which the one or more attributes captured does not match the one or more attributes stored in the database or a situation in which the one or more images captured does not match the one or more images stored in the database; under this situation, a mismatch occurs. For example, in this situation of the mismatch, a wrong number is inputted or a wrong barcode is scanned for the item.


Further referring to FIG. 2(A), at step 207, the computing device or server determines whether any mismatch is identified. In response to determining that no mismatch is identified (NO branch of decision step 207), at step 208, the computing device or server processes a normal transaction of the item. In response to determining that the mismatch is identified (YES branch of decision step 207), at step 209, the computing device or server pauses a checkout process of the item. The computing device or server may prompt a warning message to the customer about the mismatch; for example, computing device or server may prompt a warning message about an entry error of the number.


Further referring to FIG. 2(A), at step 210, the computing device or server calculates a difference between a price corresponding to one of the barcode, the number, and the item name and an actual price of the item. The actual price of the item is a price corresponding to the one or more attributes captured by the one or more sensors. In another embodiment, the actual price of the item is a price corresponding to the image captured by the one or more imaging devices. System 110 retrieves from the database the price corresponding to one of the barcode, the number, and the item name and the actual price. If the price corresponding to one of the barcode, the number, and the item name is less than the actual price of the item, there will be a loss to the store; if the price corresponding to one of the barcode, the number, and the item name is greater than the actual price of the item, there will be a loss to the customer. At step 211, the computing device or server determines whether the loss due to the mismatch occurs to the store or to the customer. In response to determining that the loss due to the mismatch occurs to the store, the computing device or server will execute step 212 (shown in FIG. 2(B)). In response to determining that the loss due to the mismatch occurs to the customer, the computing device or server will execute step 214 (shown in FIG. 2(B)).


Now referring to FIG. 2(B), at step 212, the computing device or server determines whether the difference is greater than a predetermined number of standard deviations of a normal distribution of prices of the item, where the normal distribution is based on historical data of the prices of the item. For example, if the difference is within one standard deviation, the computing device or server will not consider the difference as a significant loss to the store; if the difference is greater than one standard deviation, the computing device or server will consider the difference as a significant loss to the store.


Referring to FIG. 2(B), in response to determining that the difference is greater than the predetermined number of standard deviations (YES branch of decision block 213), at step 214, the computing device or server notifies the store to correct the mismatch. Upon receiving the notification, personnel of the store corrects the mismatch. In response to the mismatch being corrected, at step 215, the computing device or server processes a transaction of the item at the actual price of the item. Therefore, the computing device or server prevents the store from the significant loss.


Referring to FIG. 2(B), in response to determining that the difference is not greater than the predetermined number of standard deviations (NO branch of decision block 213), at step 217, the computing device or server processes a transaction of the item at the price corresponding to one of the barcode, the number, and the item name. At step 218, the computing device or server notifies the customer and the store of the difference due to the mismatch. Under the situation where the difference is not greater than the predetermined number of standard deviations, the computing device or server decide to ignore the mismatch and focus on customer satisfaction by continuing the transaction process with the wrong price. For example, in this case, the receipt given to the customer may contain information indicating savings to the customer and thus the consumer knows that the consumer obtains an unexpectedly good deal.


Referring to FIG. 2(B), under the situation where the loss due to the mismatch occurs to the customer, the computing device or server executes steps 214 and 215. Steps 215 and 216 has been described in a previous paragraph in this document. The computing device or server processes a transaction of the item at the actual price of the item; therefore, the computing device or server prevents the customer from the loss.


Referring to FIG. 2(B), following either step 215 or step 218, at step 216, the computing device or server stores information of the mismatch in the database for future transactions of the item.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.


Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.


Characteristics are as follows:


On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.


Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).


Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).


Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.


Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.


Service Models are as follows:


Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.


Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.


Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).


Deployment Models are as follows:


Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.


Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.


Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.


Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).


A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.


Referring now to FIG. 4, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices are used by cloud consumers, such as mobile device 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).


Referring now to FIG. 5, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 4) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 5 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:


Hardware and software layer 60 includes hardware and software components. Examples of hardware components include: mainframes 61; RISC (Reduced Instruction Set Computer) architecture based servers 62; servers 63; blade servers 64; storage devices 65; and networks and networking components 66. In some embodiments, software components include network application server software 67 and database software 68.


Virtualization layer 70 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 71; virtual storage 72; virtual networks 73, including virtual private networks; virtual applications and operating systems 74; and virtual clients 75.


In one example, management layer 80 may provide the functions described below.
