"POINT OF SALE SYSTEM"
FIELD OF INVENTION
This invention relates to point of sales systems particularly thought not solely to a parallel point of sale system using bar code prefix recognition.
BACKGROUND ART
It is well known in the art to use a printed bar code, such as shown in Figure 1 to identify a product. The bar code is broken up to identify the manufacturer 100, a unique product code 101 and a check digit 102. The bar codes can be in a number of formats for example Universal Product (code UPC); European Article Numbering System (EAN) and may also vary in the number of digits or in additional add on information.
When a merchant wishes to utilise a bar code an appropriate record must be added to their inventory database. Thus where an independent system using the bar code runs simultaneously (parallel) with a point of sale (POS) system, any extra bar codes for the parallel system must be entered into the database so the POS system knows to hand off those codes to the parallel system. The entry of those bar codes into the POS system can take a prohibitive amount of time and therefore it would be desirable to use a system which avoids entering all the bar codes in the POS system.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a Point of Sale system which goes someway to overcoming the disadvantages in the above mentioned prior art or which will at least provide the industry with a useful choice.
Accordingly in a first aspect the present invention may be broadly said to consist in a method of communication between a point of sale system and at least one other parallel processing system comprising the steps: inputting data to the Point of Sale system relating to a scanned bar code, retrieving a predetermined portion of said bar code and if said portion being within a predetermined group entering a null entry a the sales record for that bar code and if not then recording the relevant transaction data into said sales record if said portion of said bar code is within said predetermined group them providing said bar code to said parallel processing system,
receiving any additional transaction data to be added to said sales record from said parallel processing system, and producing a composite sales record based on said transaction data from said Point of Sale system and said additional transaction data from said parallel processing system.
Preferably said portion relates to the manufacturer prefix portion of a bar code.
Preferably said predetermined group identifies that barcode as a tickets for a retail gaming system.
Preferably said retail gaming system comprises a lottery and said bar code comprises a lottery number.
Preferably said Point of Sale system includes business logic to determine whether said portion of said bar code follows within predetermined group.
Preferably said additional transaction data supplied by said parallel processing system may comprise information on whether or not said lottery ticket was a winning ticket and or detail of any prizes won.
Preferably said additional transaction data from said parallel processing data system further comprises an additional lottery ticket.
To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.

DETAILED DESCRIPTION
The present invention takes advantage of the highly successful universal product code (upc) technology. Universal product codes are standardised codes used to designate items.
The term "merchandise" is used to refer to items which are uniquely identified by a specific universal product code. For example the right to a 10% discount on all purchases can be identified by a upc, as can a service.
In the preferred embodiment the system consists of a merchants POS system and a parallel processing system (PPS).
The merchants POS comprises a central processor 201 with a database 202 having merchandise and inventory data. Each type of merchandise has a bar code with the upc associated with it, Stored in the database 202. The POS system has sales terminals 203 and 204 coupled to central processor 201, and at least one bar code reader 206 located with and connected to each sales terminal 204. Each of the bar code readers for scanning the bar code inputs the same data through the sales terminal 204 to the central processor 201 which in turn transfers data associated with merchandise from the central processor 201 to the sales terminal 204. Preferably the POS system allows payment including but not limited to card readers 205 for reading data stored on the magnetic strip of a card. Also the sales terminal 204 may include one or more device 208 for displaying information. The display device 208 may display a brief description and the price of the merchandise identified by the upc.
As illustrated in Figure 2 the point of sale system includes a upc interpreter 210 which relates to business logic programmed in addition to the normal point of sale processing software. The interpreter could equally be provided in a separate unit between the reader and POS, or integrated with either the reader or PPS. The interpreter 210 looks up the manufacture prefix in a look up table and if it falls within a list of special manufactures codes then the business logic instructs the point of sale system to insert a null entry in the sales record for that bar code.
The processing continues normally for the special bar codes and normal bar codes alike. At the end of the transaction the bar codes relating to the special prefix are passed to the PPS 212. The PPS 212 may implement anyone of a range of actions on the selected bar codes. In the preferred embodiment of the present invention the special bar codes comprise lottery tickets and the PPS 212 interrogates a database 214 to determine whether or not each bar code correspondents to a winning lottery ticket. Once all the special bar codes have been checked by the PPS 212 then the PPS 212 returns additional transaction data to the point of sale system. This returned data to be appended to the end of the sales record includes the result of any lottery tickets ie. whether the customer has won a prize or not and may also include a further lottery ticket at the end of the sales record.
In the preferred embodiment the PPS 212 is connected to the Internet or other network connections to the central processor 201 which inturn communicates all data to each sales terminal 204. It will be appreciated by one skilled in the art that variations on this theme for
example smart sales terminal that include their own data store where by the PPS 212 communicates directly to the sales terminal 204.
