<P>PROBLEM TO BE SOLVED: To prevent a purchaser on a diet from taking in constituents in the amount obviously exceeding a limit, and enable products to be sold to the maximum extent within the limit of the purchaser's intake. <P>SOLUTION: A sale is automatically made in such a manner that when a user purchases a product, the sale does not exceed the pre-registered limit amount of intake judging from the information on the product constituents. Before each sale is made, a manager's permission is sought to prevent the user from taking in the constituents obviously exceeding the limit amount. Selling by measure is possible by registering a standard selling unit and a standard selling unit price of a product so as to strictly manage the purchaser's intake of constituents. <P>COPYRIGHT: (C)2007,JPO&INPIT |
