Title: System and method for ordering foodstuff, machine readable recording medium having foodstuff ordering program recorded thereon and foodstuff ordering program
Inventor: HAGIWARA SHINICHI
IPC: G06Q30/02
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a foodstuff ordering system having excellent practical values. SOLUTION: The ordering management device 2 of a gas company transmits menu data for displaying it on the terminal equipment 1i of a customer. The customer in turn transmits the ordering data of a foodstuff on a menu selected from displayed menu data. On receiving the ordering data, the device 2 generates a purchase order for delivering the ordered foodstuffs to the customer and transmits it to the order reception management device 3 of a foodstuff agency. The cost of the ordered foodstuff is collected from the customer with a gas rate. When the foodstuff agency completes foodstuff delivery to the customer according to the received purchase order, a completion notice is transmitted to the device 2. Then, a foodstuff cost which is simultaneously collected with the gas rate is paid to the foodstuff agency from the gas company.  Hence the rate of the ordered foodstuff can simultaneously be collected with the gas rate which is constantly collected. The foodstuff agency can thus save the labor and the expense of the collection of the foodstuff cost to make the system most practical.
