<P>PROBLEM TO BE SOLVED: To provide an improved technique to provide to consumers incentive rewards to purchase a product. <P>SOLUTION: In this system, purchase incentives are provided to consumers in the form of electronically-displayed reward coupons. No paper and ink is required. The consumer can make a real time selection of a coupon related to a product in a commercial being shown on television, for example. A code transmitted with that commercial is stored in the system if the consumer makes a selection, and that code is used to retrieve coupon display data from a set of pre-stored coupons. The retrieved coupon data is displayed on a portable device such as a personal digital assistant (PDA). The displayed coupon is processed by the merchant, such as by scanning a bar code displayed by the PDA with the coupon. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
