Abstract
A lottery ticket is generated from a customer receipt by listing on the receipt the UPC codes of the items purchased by the customer. The UPC codes can be used as lottery numbers. To enhance security, it is optional to subject the UPC numerical codes on each receipt to a predetermined numerical algorithm to generate a lottery number. The lottery numbers generated are stored to memory of the inventory computer, and, once a week, or some other period, the computer randomly selects one or more of the stored numbers as winning numbers. The winning numbers are posted to allow the players to match the lottery numbers of their receipts to the winning number list. Forgery is discouraged by reexecution of the numerical algorithm on the UPC numbers on the receipt as a check of the lottery number on the receipt.
