This invention relates to a lottery ticket transaction system. More particularly, the present invention relates to a system and a method for selling lottery tickets using point-of-sale (“POS”) terminals that generate sales receipts containing both merchandise sales information and lottery ticket information.
Many states in the United States, as well as some foreign countries, have government-conducted lottery systems. Government-conducted lotteries offer the public a desirable product (usually the chance to win a large cash prize), and have the benefit of increasing governmental revenues without burdening the public with additional or increased taxes. In many instances, the revenue generated from a governmental lottery is dedicated to a particular purpose or goal, such as improving the education system or reducing property taxes.
In a typical government-conducted lottery system, a central lottery computer is used to communicate with dedicated lottery terminals. A player selects numbers on a lottery playslip, and the lottery terminal operator inserts the lottery playslip into a reader at the lottery terminal, which optically reads the lottery playslip using a known mark-sense process. The dedicated lottery terminal then communicates the player's selected numbers to a central lottery computer which in turn stores them. After the lottery numbers have been stored, the dedicated lottery terminal, under the control of the central lottery computer, prints and issues the lottery ticket.
One popular lottery game, known as “lotto,” typically requires the player to choose six numbers from one to forty-two. The selected group of numbers are then compared to the winning lottery numbers, which have been randomly selected from the larger pool of numbers, from one to forty-two, at some specified time and date after purchase of the lotto ticket, usually once or twice each week. To win a prize, the lotto ticket numbers must be equal to all or some of the winning lottery numbers.
While players may select their own lottery numbers, most lotto games provide the option of having the central lottery computer system select random “quick-pick” lottery numbers instead This saves the purchaser the time and inconvenience of picking his or her own numbers. These automatic lottery number generation systems are usually known as “quick-pick” systems.
A variety of games may be played in a typical lottery. In conventional lottery games, a player purchases a lottery ticket. Inscribed on that lottery ticket are one or more lottery numbers and a serial number. The serial number functions as a simple method of fraud prevention, because it uniquely identifies each lottery ticket sold. The lottery number also allows both the player and the lottery system to identify a winner; specifically, the lottery numbers are compared by the player to a “winning number list”, to determine if the player has won a prize.
There are also instant lottery games in which the outcome is determined prior to the sale of the lottery ticket. By uncovering concealed indicia inscribed on the lottery ticket, the player can determine if the lottery ticket is a winner—immediately after purchase.
Some foreign countries (e.g. Germany) allow a lottery player to purchase fractional lottery tickets. However, these lottery systems only allow the player to purchase fixed fractions of certain high-priced lottery tickets (e.g., a half, or quarter share of a lottery ticket). In these instances, if the lottery ticket is a winner, the purchaser will only receive one-half or one-quarter of the full prize amount.
The majority of lottery tickets are sold by grocery, liquor and convenience stores. These retail stores typically place the dedicated lottery terminal away from one or more POS terminals used for merchandise transactions. This physical separation is to ensure that the merchandise transaction line is not slowed-down or blocked by customers wishing to make lottery ticket purchases. In addition, since the lottery terminals have a separate and distinct accounting system, there is no need to co-locate the POS terminals and dedicated lottery terminals.
However, some customers may consider it annoying to make two separate transactions, i.e., merchandise and lottery tickets, on two different terminals within the same store. Separate terminals may also force the customers to wait in two separate lines, or may slow down the overall merchandise check-out procedure while a single store clerk performs two separate transactions on two terminals. Besides annoying the merchandise-only customers, these inconveniences also reduce the impulse purchasing of lottery tickets, which in turn leads to loss of revenue for the government and the store.
There are other disadvantages with using two separate and distinct terminals for merchandise transactions and lottery ticket transactions The government usually bears the costs of purchasing, leasing, installing and maintaining the dedicated lottery terminals. There are also the considerable costs of resupplying the lottery ticket paper and ink for each dedicated lottery terminal. Moreover, many retail stores with multiple checkout lines and registers, such as supermarkets, do not have the resources to support dedicated lottery terminals at every check-out register. In addition, a dedicated lottery terminal uses counter space that could otherwise be devoted to revenue-producing merchandise displays. It is also costly to train store personnel in the operation of two distinct types of transaction terminals. These factors reduce the availability of lottery tickets to consumers, and thus reduce governmental revenue, by limiting the number of locations that sell lottery tickets.
After many years of steadily increasing profits, many state-run lotteries have seen a downturn in profits. Improving the ease of purchasing lottery tickets and increasing their availability has become a primary concern as many states are modernizing their lottery systems. The current lottery system does not allow for the sale of fractional value lottery tickets at retail point of sale terminals. There is a significant loss of revenue from this lost opportunity to buy fractional value lottery tickets. Accordingly, there is a need for a system that solves the above described problems.
The present invention solves the foregoing problems by providing a system and a method for performing integrated lottery ticket and merchandise transactions. The system and method utilizes POS terminals that generate a single sales receipt containing all lottery ticket and merchandise information.
In accordance with one embodiment of the present invention, each POS terminal is connected to a POS controller, which in turn is adapted to communicate with a lottery data processing system. The POS terminal is designed to perform lottery transactions in addition to merchandise transactions. Accordingly, during the course of purchasing merchandise, the buyer can also request the purchase of a lottery ticket. The POS terminal operator thereupon actuates a pre-programmed key or other coded input on the POS terminal, which causes the terminal to transmit a lottery ticket request to the POS controller. The controller transmits this request to the lottery data processing system, which carries out the lottery transaction. The lottery data processing system then transmits lottery ticket information back to the POS terminal. The POS terminal completes the transaction by printing out a single sales receipt containing both lottery ticket information and information concerning the merchandise being purchased.
The present invention advantageously eliminates the need for a separate lottery ticket system and terminal which in turn eliminates the added costs of the check-out counter space associated therewith. This provides the lottery ticket purchaser with a convenient and efficient means of buying lottery tickets while making non-lottery ticket purchases at the POS terminal. The present invention also advantageously provides the consumer greater access to lottery tickets by increasing the number of locations capable of selling lottery tickets.
In accordance with another embodiment of the present invention, lottery players may purchase fractional lottery tickets at the POS terminal. Any fraction or percentage of a full lottery ticket can be requested by the customer (i.e. one to ninety-nine percent). The customer is not limited to any preset or fixed fractions. This is advantageous for customers who are making other merchandise transactions and who do not wish to receive change (coins totalling less than a dollar). Instead of receiving a handful of change, the customer can request his change be used for purchasing a fractional lottery ticket. In this embodiment, the lottery player would only receive a fraction of a winning prize based on the fraction of the lottery ticket purchased.
In accordance with another embodiment of the present invention, lottery players may telephone the lottery data processing system via an interactive voice response unit (IVRU) to verify the validity of the lottery ticket information. The player inputs to the IVRU via the telephone keypad the encrypted authentication code printed on the sales receipt, and this code is decrypted by the lottery data processing system and used to verify the lottery ticket.
The present invention is directed to a system for performing lottery ticket transactions at retail POS terminals without the customer having to wait for two transaction receipts, or go to another check-out terminal to make other non-lottery ticket purchases. In about the same amount of time it takes to ring up bread or milk at a POS terminal, the customer can also purchase a “quick-pick” lottery ticket. This one-stop shopping facilitates the sale of lottery tickets, and speeds the customer on his way. In addition, the present invention enables the customer to purchase fractional lottery tickets which even further facilitates the sale of lottery tickets. In particular, in cases where a customer makes other merchandise purchases, instead of receiving change, he can request a fractional lottery ticket (equal to the change amount). Accordingly, the present invention provides a consumer with a convenient and efficient system to purchase lottery tickets.
The term “quick-pick” refers to a lottery ticket in which the lottery numbers are randomly generated for the customer by the lottery system.
A fractional lottery ticket is a lottery ticket in which the customer will receive only a portion of the winning prize in accordance with the fractional portion paid for the ticket as compared to the full price of a lottery ticket. For example, if a customer pays 58 cents for a fractional lottery ticket where the full price of a lottery ticket is a dollar, the customer would receive fifty-eight percent of the prize amount if the ticket is a winner. As used herein, the term “lottery tickets”, or equivalents thereof includes fractional lottery tickets.
As illustrated in
The POS terminals 30 and the POS controller 20 depicted in
The POS controller 20 also includes a communication port 25 connected to a data network interface 71 and a POS network interface 72. The communication port 25 enables the CPU 21 to communicate with devices external to the POS controller 20. In particular, the communication port 25 permits communication with the POS terminals 30 and also with the lottery data processing system 60. While a modem (not shown) and a dedicated telephone line for establishing communication with the lottery data processing system 60 is preferred, other data network interfaces, including an ISDN terminal to interface with an ISDN network, a radio communications interface, and an Internet interface, may be used as well.
The CPU 21 can also store information to, and read information from, a data storage device 26. The data storage device 26 includes a local lottery ticket database 26a and other databases including a local sales database 26b that a store may conventionally maintain. The local lottery ticket database 26a is described below. In addition, the data storage device 26 includes instructions which can be read by and executed by the CPU 21, thereby enabling the CPU 21 to process transactions. While
While only three records R1 for three lottery ticket transactions are depicted in
The POS terminal 30 includes an input device 37 to receive input from an operator. Any one of a variety of input devices would be suitable for this purpose, including, for example, depression-actuated buttons, keys, membranes, a mouse, touchscreens, bar code scanners, and the like. The input device 37 may interface directly with the CPU 31, as shown in
The POS terminal 30 also includes a display device 38 for conveying information to the operator, customer or both. Any one of a variety of display devices would be suitable for this purpose, including, for example a CRT, LCD, LED or thin film transistor panel.
The POS terminal 30 also includes a data storage device 36, in which transaction processor instructions are stored. These instructions can be read by and executed by the CPU 31, enabling the POS terminal 30 to process a variety of transaction types. By way of example, these transaction types may include “quick-pick” lottery tickets, lottery tickets other than “quick-pick” tickets and merchandise transactions.
The POS terminal 30 further includes a printer 39 for recording the transaction performed by the POS terminal 30. The printer 39 may interface directly with the CPU 31, as shown in
It will also be understood that other combinations of POS controllers 20 and POS terminals 30 could be employed, depending upon the requirements of a particular establishment. In particular, the POS terminal 30 may incorporate some of the features of the POS controller 20 so that the integrated POS terminal/controller can function as a stand-alone unit. This type of terminal would be advantageous for establishments that only require a single POS terminal.

As shown in
The CPU 61 can also store information to, and read information from the data storage device 68. The data storage device 68 includes a lottery ticket database 68a, a POS controller database 68b, and a winning lottery ticket number database 68c which are described below. In addition, the data storage device 68 includes instructions which can be read by and executed by the CPU 61, thereby enabling the CPU 61 to process lottery transactions. While
The lottery data processing system 60 also includes a random number generator 66 and a cryptographic processor 67. When requested by the CPU 61, the random number generator 66 generates the random “quick-pick” numbers used for “quick-pick” lottery ticket transactions The cryptographic processor 67 is used to encrypt an authentication code generated by the CPU 61, described in greater detail below. This encrypted authentication code is passed to the CPU 61 which associates it with a particular lottery transaction. The cryptographic processor 67 is also used to decrypt encrypted authentication codes which are passed to it by the CPU 61.
While the illustrated embodiment depicts the random number generator 66 and the cryptographic processor 67 as separate elements within the lottery data processing system 60, it should be understood that other methods of performing their functions may be used. For example, these functions may be implemented in a computer program stored in the data storage device 68 and executed by the CPU 61.
While record R2 for one POS controller with ID number 23456 is depicted in
It should be understood that some fields within the databases discussed above would contain the same corresponding information (e.g. POS controller ID number field F6 in the lottery ticket database 68A corresponds to field F13 in the POS controller database 68B).
The number of “quick-pick” lottery tickets may also include fractional lottery tickets. This is convenient for customers who do not want to receive a handful of coins as change from a transaction. For example, a customer due sixty-eight cents in change, from a merchandise purchase could elect to buy a lottery ticket for sixty-eight cents which is worth 68% of a $1 ticket and which pays-out sixty-eight percent of the $1 payout. Alternatively, the customer could buy a 34% value of a $2 ticket with 68 cents. Along with the fractional value lottery tickets, the customer may of course purchase full value lottery tickets.
In an alternative embodiment, the customer may also be prompted for additional lottery ticket information, such as the type of lottery game to be played and the particular lottery numbers selected by the customer. For example, a particular lottery system may offer lottery games based on three, four and six number combinations. The customer may also personally select the lottery numbers to be played.
In step S4, the POS terminal operator enters the number of lottery tickets requested by the customer into the POS terminal 30 via the input device 37. The customer pays for the lottery tickets and any other purchases made at this time in step S5. In step S6, the POS terminal prints a single receipt containing the lottery ticket information and any other merchandise sales information.

While one lottery data processing system 60 is depicted in
Once the real-time communication link is established, the POS controller 20 in step S8 transmits the number of “quick-pick” lottery tickets requested to the lottery data processing system 60. The POS controller 20 also transmits its POS controller identification number (e.g. F1 in
Each of the steps S7-S12 described above is executed by the CPU 21 which is executing computer program instructions stored in the data storage device 26. The communication with the POS terminal 30 takes place via the communication port 25 and the POS network interface 72. The communication with the lottery data processing system 60 takes place via the communication port 25 and the data network interface 71.
In an alternative embodiment, the POS controller 20 may also handle non-“quick-pick” lottery ticket transactions. Customer-selected lottery numbers would be received from the customer via mark-sense slips or coded chits at the POS terminal 30 and sent to the lottery data processing system 60 for processing, as described below.
In step S16, the lottery data processing system 60 generates one or more groups of random “quick-pick” lottery numbers using the random number generator 66 (shown in
The lottery data processing system 60 also generates an authentication code based on the variables of the particular lottery transaction in step S17. This authentication code is a numeric string including all the data of one record in the lottery ticket database 68a. An example of such a code corresponding to the first entry shown in
23456/011597004/3343004/011020112131
In this example, 23456 represents the POS controller ID number; 011597 represents the date; 004 represents the number of tickets purchased; 3343 represents the sales receipt number; 004 represents the sales amount; and 011020112131 represents the lottery ticket numbers.
While the use of an encrypted authentication code is the preferred embodiment, it should also be understood that the store sales receipt number along with the date for each transaction may be used instead. In this situation, the sales receipt number and the date would be used as a pointer to the lottery ticket database 68a. This pointer would be used to extract and verify lottery ticket information as required.
In step S18, using the cryptographic processor 67 (shown in
The lottery data processing system 60 then transmits the lottery ticket numbers and the encrypted authentication code to the POS controller 20 initiating the lottery ticket transaction in step S19.
This authentication code provides an added level of security and protection for the purchase of the lottery ticket. Should the database within the lottery data processing system 60 be corrupted, all the information printed on the store receipt lottery ticket can still be verified by any other device capable of decrypting the authentication code.
Each of the steps S13-S19 described above is executed by the CPU 61, which carries out these steps by executing computer program instructions stored in the data storage device 68. The communication with the POS controller 20 takes place via the communication port 65 and the data network interface 71.
In an alternative embodiment, additional information may be transmitted from the POS controller 20 to the lottery data processing system 60. This could include, as described above, customer-selected lottery numbers instead of the random “quick-pick” lottery numbers generated by the lottery data processing system 60. In this situation, the lottery data processing system 60 would store the customer-selected lottery numbers in the lottery ticket database 68a. An encrypted authentication code would be generated accordingly based on the customer-selected lottery numbers. The lottery data processing system 60 would then send the encrypted authentication code and authorization to complete the lottery transaction to the POS controller 20.
In step S23, the lottery data processing system 60 searches the cryptographic code field F12 in the lottery ticket database 68a to find an entry that matches the information provided from the IVRU 75. If no match is found, the lottery data processing system 60 communicates to the IVRU 75 that the encrypted authentication code provided by the customer is not valid. The IVRU 75 then prompts the customer to re-enter the encrypted authentication code. After a predetermined number of failed attempts to correctly enter a valid code, the call is terminated, as shown in step S24.
If a matching entry is found, the lottery data processing system 60 decrypts the encrypted authentication code. The decrypted information is then communicated to the customer assistance IVRU 75 in step S25. Based on this information, the customer assistance IVRU 75 transmits a voice message to the customer providing all the decrypted information (i.e. lottery ticket number, time and date of purchase, etc.). The customer assistance IVRU 75 creates the voice message by combining pre-recorded voice messages stored therein.
A winning lottery ticket may be redeemed at one of the POS terminals 30 or at any conventional lottery terminal. To redeem the winning lottery ticket at one of the POS terminals 30, the POS terminal operator initiates a lottery ticket verification process by actuating a pre-programmed input designator via input device 37 associated with the POS terminal 30. The POS operator then enters the encrypted authentication code printed on the lottery ticket into the POS terminal 30 via the input device 37. This information is transmitted to the lottery data processing system 60 via the POS controller 20. The lottery data processing system 60 decrypts this information and accesses the lottery ticket database 68a and the winning lottery ticket number database 68b. The lottery data processing system 60 then determines whether the lottery ticket is a winning lottery ticket based on the information contained in the respective databases.
This determination (along with other information as needed) is then communicated back to the POS terminal 30 via the POS controller 20. Other types of information that may be included in this communication are, for example, the winning prize amount, the fractional prize amount, and whether or not there was a jackpot winning ticket.
In an alternative embodiment, the random “quick-pick” lottery numbers used for a lottery ticket transaction may be generated by the POS controller 20. These lottery numbers would then be transmitted to the lottery data processing system 60 as described above.
There are thus provided new and improved systems and methods for selling lottery tickets at point-of-sale locations in stores. The invention uses the same equipment provided for processing conventional store sales of merchandise and/or services to process lottery ticket sales.
The dual utility of the sales equipment makes the invention cost-effective for merchants. The systems and methods provided permit speedy and efficient purchasing of lottery tickets while making routine purchases of other goods, thus encouraging impulse purchasing of lottery tickets without delaying the regular flow of the point-of-sale checkout line. Further, the invention enables the quick and efficient sale of fractional lottery tickets with what would otherwise be customer change, again encouraging impulse purchases, thereby increasing the market for lottery tickets.
The present invention further provides systems and methods whereby an easy to print, easy to read, sales receipt is printed containing both the sales of goods/services and lottery ticket information. The ticket includes authenticating information, including at least one authenticating code and a customer service telephone number, which the customer can use to verify his lottery numbers with the lottery authority.
While the present invention has been described above in terms of specific embodiments, it is to be understood that the invention is not intended to be confined or limited to the embodiments disclosed herein On the contrary, the present invention is intended to cover all methods, structures and modifications thereof included within the spirit and scope of the appended claims.
