Abstract

To provide a purchase management system using self registers that can call attention and prevent a predetermined number or more of commodities from being registered when commodities whose quantity is limited are purchased.SOLUTION: A server device receives commodity identification information from a portable terminal to make a purchased commodity list. Then, the server device determines whether the number of commodities, whose quantity is limited, included in the purchased commodity list is greater than a limited number on the basis of commodity information. If the number of the commodities whose quantity is limited is determined to be greater than the limited number, the server device generates a warning screen to transmit it to the portable terminal. The portable terminal displays the warning screen received from the server device.SELECTED DRAWING: Figure 16
