Abstract: A manufacturers' coupon redemption system that is electronically controlled, and compatible in any supermarket using Universal Product Codes. The system includes a newly-styled, uniform coupon, with special bar code indicia redeemable on up to three families of products. At the supermarket, a special device for reading the coupons is provided that reads the coupons presented by the consumer. The system verifies that the consumer did, in fact, purchase the items specified, that the coupon has not expired, and other validation conditions. The unit communicates the results of the validation to the cash register for credit to the consumer's bill. The accepted coupon is then mutiliated to prevent reuse.
