TRANSACTION PROCESSING SYSTEM AND TRANSACTION PROCESSING METHOD

Abstract

A transaction processing system 100 includes a checkout 210 in a retail store 200. The checkout 210 is configured to obtain product data from a product database 240, e.g. from a store server over a network, in response to scanning the goods at the checkout 210. The checkout 210 is further configured to obtain price comparison information from a price comparison database 250 which compares prices of the scanned goods with prices of comparable goods offered by other retailers. The checkout 210 may be configured to display messages on a display 213 during the transaction, calculate payments which may include instantaneous discounts based on the price comparison information, and to receive payments from a customer for the basket of goods.

Description

BACKGROUND

1. Technical Field

The present invention relates in general to the field of apparatus and methods for processing transactions in a retail store.

2. Description of Related Art

Typically, a customer collects a basket or trolley of goods in a retail store and then pays for those goods at a point of sale or checkout. It is known to print paper vouchers for the customer based on the value of the goods they have purchased, and/or based on one or more items included in their basket. These paper vouchers must be retained by the customer to be redeemed at a subsequent visit to the store. However, paper vouchers are relatively bulky and can be difficult to carry around. Customers frequently lose the paper vouchers, or forget to bring the paper vouchers back to the store, thus losing the benefit of their vouchers. Further, processing and redeeming the paper vouchers is relatively slow, which increases the total time taken for some transactions. Such delays can be inconvenient for customers and can add to the transaction processing costs for the store. These transaction processing delays can be particularly inconvenient during busy periods in the store.

The example embodiments aim to address at least some of these difficulties of the related art, or other difficulties as will be appreciated from the description below.

At least some of the following example embodiments provide an improved transaction processing system. Many other advantages and improvements will be discussed in more detail below, or will be appreciate by the skilled person from carrying out example embodiments based on the teachings herein.

FIG. 1 is a schematic view of an example transaction processing system 100. Conveniently, the transaction processing system 100 is adapted for use in at least one retail store 200 where goods are chosen by the customer and paid for at a point of sale terminal or checkout 210. The customer typically places their chosen goods into a trolley, basket or other carrier while moving around the store. A basket of goods thus refers to a collection of one or more items which are to be purchased in the current transaction. Each store 200 suitably includes several such checkouts 210, as will be familiar to those skilled in the art. The checkouts 210 can be operated by employees of the store, and/or may be self-checkout terminals intended to be operated by the customer themselves, usually under supervision by the store employees. Each checkout 210 may include a scanner 211, such as a bar-code reader, to identify the goods being purchased. The checkout 210 may include a payment mechanism 212 to receive payments, such as a card reader and/or a cash drawer. The checkout 210 may include one or more display screens 213 which provide visual feedback to the store employees and/or the customers during each transaction. The checkout 210 may include a printer 214 to print a till receipt and other information to be carried away by the customer.

In this example, each store 200 includes one or more local store servers 220 which are linked to the checkouts 210 by a local communication network 230. The local area network 230 may take any suitable form, including secure wired and/or wireless communication links, as will be familiar to those skilled in the art. The store server 220 may hold a local product database 240 with information about each of the products offered by the store. The product database 240 suitably holds identifiers for product items (e.g. stock keeping units SKUs), pricing information, current offers or discounts (e.g. multi-buy offers), and so on.

One or more master servers 310 may be linked to each store 200 over one or more wide areas networks 330, which may take any suitable form including wired and/or wireless communication links, as will be familiar to those skilled in the art. In one example, the wide area network 330 may include a virtual private network VPN over the Internet, or dedicated leased lines. The master servers 310 may be located, for example, at one or more central or regional data processing sites 300 operated by the retailer. The master servers 310 may hold a main product database 340 as a master record of the products offered by the retailer in their stores. The master servers 300 may post updates to each store 200, e.g. each night or several times each day, thereby providing current information from the main product database 340 to update each local product database 240.

During a transaction, each product item which passes the scanner 211 at the checkout 210 triggers a lookup of respective price data from the local product database 240. In the example embodiment, the checkout 210 sends the product identifier of the scanned product over the local network 230 to the store server 220. The corresponding price data and product information from the local product database 240 is returned to the checkout 210 and may be displayed on the display 213 by way of confirmation. Conveniently, the checkout 210 includes a data processing and data storage capability to monitor the current transaction and, inter alia, maintain a running total of the plurality of items within the current transaction. In one example, the checkout 210 thus calculates a final total basket price, ready to receive payment via the payment mechanism 212 to complete the transaction. Suitably, the checkout 210 posts details of the completed transactions to the local store server 220 for reporting and accounting within the store, and the many transactions within each store are uploaded and reported from the store 200 back to the data processing centre 300.

There is an increasing desire to offer price transparency to the customer. Further, there is an increasing desire to allow customers to compare the prices of several different retailers. Typically, price comparison websites offer an interface via the Internet which allows the price of certain goods to be compared between several retailers. However, to make a price comparison, the customer must visit the website via an Internet-connected device such as a laptop or tablet computer, and carefully select the items of interest. Notably, it is relatively difficult and inconvenient to use a price comparison website while the customer is actually within the retail store. Hence, price comparison websites tend to be restricted in use only to a select group of customers who have the interest, ability and time to use those websites. Also, price comparison is typically performed while at home or otherwise away from the retail stores.

In the example embodiment, the transaction processing system 100 further comprises a price comparison database 350 which compares the prices of one or more products offered by the retailer with the price of one or more comparable products offered by other retailers. In this example, the main servers 310 of the data processing centre store one or more master copies of the price comparison database 350. The master price comparison database (or databases) 350 may, for example, be created by robotically crawling online web-shopping data from the online stores of the other retailers, or by manually observing and entering relevant price data.

In the example embodiment, the price comparison database 350 is distributed to the stores 200 over the wide area network 330 to form a local price comparison database 250 held locally within each store 200. Thus, each store 200, holds and has online real-time access to the product information and price data of the retailer (e.g. retailer A) and of the comparable other retailers (retailers B, C and D, for example), as held in the local product database 240 and the local price comparison database 250.

A difficulty arises in that the time taken to complete each transaction is a source of inconvenience for customers, especially at busy times when customers may have to queue at the checkouts 210. Also, transaction delay is a significant potential cost overhead for the store, considering that transaction throughput is important in determining the number of checkouts that need to be provided and operated, and the specification (capacity) of each checkout. Therefore, there is a need to improve transaction processing while maintaining acceptable transaction times.

In one example, the checkout 210 is configured to obtain price comparison data from the local price comparison database 250 for one or more of the scanned items. The checkout may obtain the price comparison data in real time, alongside obtaining the product data for that item.

In one example, the checkout 210 obtains the price comparison data separately for each line item within the transaction. A line item may comprise a plurality of individual scanned items (e.g. 6 individual bottles of a particular product may equate to one line item). As a result, the total transaction time is maintained to be relatively short in duration.

In one example, the checkout 201 is configured to calculate a price comparison result based on the obtained product data and price comparison information. The checkout 210 may display a message to the customer on the display 213 during the transaction based on the price comparison result. For example, the display 213 may present an appropriate message, such as “your product item XX is ££ cheaper with us today” or “we are cheaper than rivals B, C or D for your product XX”. In another example, these messages may be presented to the customer on their printed till receipt produced by the checkout 210.

In one example, the checkout 210 is configured to obtain the price comparison data for each of a plurality of items within a transaction, and to calculate a plurality of candidate basket totals. Each candidate basket total may be calculated, for example, by using the price data of a certain retailer. Suitably, each candidate basket total represents the price of that basket of items according to the price comparison data. The checkout 210 is suitably configured to compare the plurality of candidate basket totals and display an appropriate comparison result on the display screen 213 (e.g. “your basket total is ££ cheaper with us today”).

In one example, the checkout 210 may be configured to select the lowest basket total amongst the plurality of basket totals as the final basket total of the current transaction. In this example, the checkout 210 may be configured to display an appropriate message (e.g. “we have matched our prices for this basket to those of retailer C”).

In a further example, the checkout 210 is configured to calculate a discount based on comparing the plurality of basket totals. The checkout 201 may apply the discount to one or more of the basket totals in order to calculate a final basket total fro the current transaction. For example, the discount may be calculated according to the difference in price between one retailer and another. The discount may be a fixed rate (e.g. 10 pence per item) or a percentage (e.g. 50% of the difference between our price and the price of the nearest other retailer).

In one example, the checkout 210 is configured to apply the discount instantly during the current transaction. As a result, the customer instantly receives the financial benefit of the discount, which may be derived from the price comparison data as described above. Applying an instantaneous discount within the current transaction gives immediate benefit for the customer, reduces the previous need to issue and redeem paper vouchers, and reduces transaction times for the retailer.

In one example, the calculation may include caps or restrictions which limit the calculation based, for example, on weight or quantity of the items. For example, the checkout may be configured to require a minimum or maximum number of items in the basket, or a minimum or maximum number of certain items. In one example, these caps and restrictions are supplied using appropriate qualification fields carried within the product data and/or in the price comparison information obtained by the checkout in response to scanning the goods. In one example, the qualification fields are dynamically adjustable, allowing the transaction system to respond to rapidly changing retail conditions.

In one example, the price comparison database 250 and the local product database 240 may be held as distinctly separate databases linked by one or more common indexing fields such as the product identifier (e.g. the SKU). In another example, a single database may be used to combine both the retailer's own product data and the price comparison data within a combined data structure.

In one example, the product database 240 and/or the price comparison database 250, or certain subsections thereof, may be distributed on any suitable physical components of the system 100. For example, portions of these databases may be held or cached locally within each checkout 210. Such distributed databases may take any suitable form and be subject to purging, reconstruction, updating, recovery, failover and load-balancing as will be familiar to those skilled in the art.

Although the example embodiments have been illustrated with the checkout 210 performing certain tasks, other embodiments may instead cause the described processing steps to be taken by other equipment, e.g. by the store server 220. In one example, the checkout 210 may act as a relatively dumb terminal interface to receive inputs such as from the scanner 211, transmit information to the store server 220, receive replies and make appropriate outputs such as via the displays 213.

In another example embodiment, the checkout 210 may be, or may comprise, a portable or hand-held terminal suitable to be moved or carried around the retail store. The portable checkout terminal may include a bar-code reader, e.g. a camera, and a user interface, e.g. a display screen. A payment mechanism may be implemented by the terminal, e.g. by the customer inputting payment account details or otherwise connecting the terminal to a payment system. Equipment brought to the store by the customer may be operated as the checkout or may contribute to operation of the checkout, such as a mobile phone or other computing device.

The example embodiments have been described with reference to messages which are displayed on the display 213 and/or printed on a till receipt by the checkout 210 using a suitable printer 214. Other specific forms of providing such messages to the customer are also envisaged including, but not limited to, communicating with the customer electronically, e.g. by text message or email, to display the message on the customer's own device, such as their mobile phone.

FIG. 2 is a flowchart of an example method. In the example embodiments, the method may be implemented as described in detail above.

Step 201 comprises scanning one or more product items at a checkout in the retail store, by the checkout 210.

Step 202 comprises obtaining product data at the checkout 210 relating to the one or more scanned items.

Step 203 comprises obtaining price comparison information at the checkout 210 relating to one or more of the scanned items.

Step 204 comprises calculating a final payment to be received at the checkout for the scanned items. The final payment for this basket of items may be based on both the product data and the price comparison data, as explained above.
