A coupon management server 1 receives an authentication code from the portable terminal 2, and determines whether or not the authentication code is coincident with the preliminarily stored authentication code of the store. When those authentication codes are coincident with each other, the portable terminal 2 displays a confirmation screen 43, and when a use completion OK button is selected, the portable terminal 2 transmits a coupon code, the authentication code and a terminal ID. The coupon management server 1 stores the received coupon code, authentication code and terminal ID and a reception date. The portable terminal 2 displays a use confirmation completion screen 44.;COPYRIGHT: (C)2015,JPO&INPIT
