Abstract: A method and system are disclosed for redeeming one or more coupons having an identifying barcode thereon for crediting against one or more products also having an identifying barcode thereon. The product and coupon are separately scanned at the barcodes thereof for identification. A scanned coupon is transported to a secure staging area to allow sequential scanning of additional coupons. The scanned coupon is compared with the scanned product to determine propriety of a credit thereagainst. The scanned coupon may be returned on demand, or credited against a scanned matching product when unreturned. The credited coupon is then secured for preventing unauthorized reuse. In a preferred embodiment, a plurality of the products and coupons may be scanned, with the scanned coupons being transported to the staging area for allowing return on demand of a selected one thereof.
