1. Field of the Invention
The present invention relates to a point-of-sale system for retail environments, and more particularly to a system and method for detecting and analyzing motion patterns of individuals at a self-service checkout point-of-sale.
2. Description of the Prior Art
In the retail industry, labor is the number one expense after cost of goods sold. Employees working as "checkout personnel" or "cashiers" are the single largest category of labor. This is particularly true for those retailers in the food segment. On average, the retailer must have three or more cashiers trained for every checkout lane in a food store.
One problem for retailers is the cost associated with the recruiting, hiring, training, scheduling, managing, etc. of cashiers. This cost is exacerbated in that turnover in the food segment can easily exceed 100% annually, especially in metropolitan areas. It is not uncommon for food retailers to have significantly fewer cashiers on hand in a retail establishment than is optimally required.
The constant recruiting, hiring, training, and scheduling of cashiers consumers significant management time and expense. Scheduling alone can make or break a retailer's performance on any given day and significantly impact customer service. By scheduling too many cashiers, the retailer has excess capacity and a higher cost of sales for the day. By scheduling too few cashiers, checkout queues grow long with angry customers who may not return due to poor customer service. Other customers may enter the store and go elsewhere due to the long lines. Checkout problems are typically the leading consumer dissatisfaction issue for retailers.
Self Checkout (SCO) Terminals offer benefits to both the retailer and the consumer. For the retailer, SCO terminals reduce the retailer's need for cashiers, thereby reducing the costs associated with them. Since SCO terminals are rarely closed, the job of predicting and scheduling cashier demand is made easier. For the consumer, SCO terminals offer the perception of faster checkout, privacy, control, etc., and a significantly enhanced shopping experience.
Thus, in theory, replacing traditional cashier assisted checkout with self checkout makes great business sense. However, the cashier performs several roles for the retailer in addition to itemizing and tendering groceries. One significant role is that of security--ensuring that the consumers pay for all the groceries that they take out of the store. A SCO terminal can enable the consumer to take the cashier's place in itemizing and tendering. But the concern remains how to ensure that the consumer pays for all the items taken out of the store.
Loss prevention specialists know that the probability of theft increases when someone believes an opportunity exists to deceive without an offsetting risk of detection/consequence. By removing the cashier, the consumer is no longer faced with a significant method of detection.
Typical SCO solutions have used technologies that are not consumer friendly, are perceived as non-trusting, fail to support the consumer throughout the transaction, and have placed added operational issues on the retailer.
There is therefore a significant need in the art for a system and method for providing security for self checkout environments in a way that is effective and efficient, but is also acceptable to the consumer.
