ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a checkout system, and more particularly to an apparatus and method for operating a checkout system having a number of port expander devices associated therewith.
BACKGROUND OF THE INVENTION
In the retail industry, the largest expenditures are typically the cost of the goods sold followed closely by the cost of labor expended. With particular regard to the retail grocery or supermarket industry, the impetus to reduce labor costs has focused on reducing or eliminating the amount of time required to handle and/or process the items or goods to be purchased by a customer. To this end, there have been a number of self-service checkout systems developed which attempt to substantially eliminate the need for a checkout clerk.
A self-service checkout system is operated by a customer without the aid of a checkout clerk. Hence, during operation of a self-service checkout system, the customer scans individual items for purchase across a scanner and then places the scanned items into a grocery bag, if desired. The customer then pays for his or her purchases either at the self-service checkout system if so equipped, or at a central payment area which is staffed by a store employee. Thus, a self-service checkout system permits a customer to select, itemize, and in some cases pay for his or her purchases without the assistance of the retailer's personnel.
It should be appreciated that a given retailer may have a number of reservations in regard to implementation of self-service checkout systems into the retailer's operation. For example, certain self-service checkout systems which have heretofore been designed are more expensive relative to assisted checkout systems (i.e. retail checkout systems which are operated by an employee of the retailer such as a checkout clerk). The higher cost associated with a self-service checkout system is typically due to the fact that the system itself must perform functions that would normally be performed by the checkout clerk operating the checkout system thereby increasing the number of components associated with the self-service checkout system. For instance, in the case of a self-service checkout system, the system must provide security from improprieties such as theft. Moreover, in certain self-service checkout systems, the checkout system itself must collect payment from the customer for his or her items for purchase. It is the cost of the hardware and software necessary to provide such functions to the self-service checkout system which in certain cases cause the cost of the system to typically exceed the cost of an assisted checkout system.
Moreover, a number of retailers fear that the retailer's customers may not embrace the idea of using self-service checkout systems to checkout their items for purchase thereby potentially causing the systems to go unused in the retailer's store. In such a situation, the retailer would have expended a relatively substantial sum of money for a checkout system which is not being utilized thereby increasing costs associated with the retailer's operation.
Yet further, it is generally recognized that a well-trained checkout clerk is capable of completing a checkout transaction in a more timely manner relative to an untrained customer. Accordingly, during periods of peak demand within the retailer's store, it is desirable for the retailer to operate a relatively large number of assisted checkout systems in order to expedite the checkout process thereby preventing customers from undesirably being forced to wait in long checkout queues. However, during periods of lesser demand within the retailer's store, it is desirable for the retailer to operate a relatively large number of self-service checkout systems in order to reduce the number of employees (i.e. checkout clerks) that the retailer must have present in the store. Hence, a compromise must be made between the number of assisted checkout systems and the number of self-service checkout systems which are installed in the retailer's store.
What is needed therefore is a checkout system which overcomes one or more of the above-mentioned drawbacks. What is particularly needed is a low-cost, easy-to-operate checkout system that may be operated as either an assisted checkout system or a self-service checkout system. What is further needed is a checkout system that may be operated as either an assisted checkout system or a self-service checkout system that can be quickly and easily converted between the two types of systems.
SUMMARY OF THE INVENTION
In accordance with a first embodiment of the present invention, there is provided a retail terminal. The retail terminal includes a controller having a controller data port. The retail terminal also includes a port expander device having a first expander data port, a second expander data port, and a third expander data port. The retail terminal further includes a first retail peripheral device having a first peripheral data port. Moreover, the retail terminal a second retail peripheral device having a second peripheral data port. The controller data port is electrically coupled to the first expander data port via a first signal line. The first peripheral data port is electrically coupled to the second expander data port via a second signal line. The second peripheral data port is electrically coupled to the third expander data port via a third signal line.
In accordance with a second embodiment of the present invention, there is provided a retail terminal. The retail terminal includes a controller having a controller data port which is configured as a first interface type. The retail terminal also includes a port expander device having (i) a first expander data port which is configured as the first interface type, and (ii) a second expander data port which is configured as a second interface type. The retail terminal further includes a retail peripheral device having a peripheral data port which is configured as the second interface type. The controller data port is electrically coupled to the first expander data port via a first signal line. The peripheral data port is electrically coupled to the second expander data port via a second signal line.
In accordance with a third embodiment of the present invention, there is provided a retail terminal. The retail terminal includes a first terminal cabinet and a second terminal cabinet. The retail terminal includes a controller secured to the first terminal cabinet, the controller having a controller data port associated therewith. The retail terminal also includes a port expander device secured to the second terminal cabinet. The port expander device has a first expander data port, a second expander data port, and a third expander data port associated therewith. The retail terminal also includes a first retail peripheral device secured to the second terminal cabinet. The first retail peripheral device has a first peripheral data port associated therewith. The retail terminal further includes a second retail peripheral device secured to the second terminal cabinet. The second retail peripheral device has a second peripheral data port associated therewith. The controller data port is electrically coupled to the first expander data port via a first data cable. The first peripheral data port is electrically coupled to the second expander data port via a second data cable. The second peripheral data port is electrically coupled to the third expander data port via a third data cable.
It is therefore an object of the present invention to provide a new and useful checkout system.
It is moreover an object of the present invention to provide an improved checkout system.
It is a further object of the present invention to provide a new and useful method of operating a checkout system.
It is also an object of the present invention to provide an improved method of operating a checkout system.
It is yet another object of the present invention to provide a low-cost, easy-to-operate checkou
