Abstract
A method and system for the electronic distribution of product redemption coupons to remote personal computers located at users' homes are disclosed. A centrally located repository, such as an online service provider or web site on the Internet, stores packages of coupon data for downloading on demand to the user's computer. A coupon generated by the system and method of the present invention comprises an encoded area that consists essentially of a unique Coupon Id. The unique Coupon Id is also recorded in a database comprising a plurality of data tables. At least one of the data tables associates each Coupon Id with one or more of a Promotion Id and a Consumer Id. Preferably, the Print Id is also associated in a data table with a Session Id and information regarding the date/time of printing. The Ids other than the Coupon Id may not be printed on the coupon.
