Abstract: A method for tracking lottery sales information utilizes an unsold ticket count and a sold ticket count for a plurality of sequential-ordered lottery tickets. The unsold ticket count and the sold ticket count is continuously updated when a current work shift is closed. In order to close the current work shift, identification data from a first-remaining lottery ticket is received. The identification data is transferred through a scanning device. When the identification data is received, the unsold ticket count and the sold ticket count is updated accordingly. Next, the sold ticket count and the unsold ticket count are used to determine a sales sharing percentage and a space sharing percentage. Based on the space sharing percentage and the sales sharing percentage future orders for a plurality of ticket types are adjusted such that the overall profit of a store is maximized.
