  • Method and system for handling discount coupons by using centrally stored manufacturer coupons in place of paper coupons
    Patent number: 5185695
    Abstract: The method and apparatus for creating and processing discount coupons includes central processor (16) for receiving from manufacturers information of product type, validation period and coupon value and for producing a central coupon list of available coupon discounts. The central list is transmitted to local processors (19) of retailers (18) whom hold manufacturer products for sale. The local processor (19) produces a local coupon list based on the central list containing only those manufacturers and product type which the retailer holds for sale. A coupon indicia (12) is printed by a printer (38) and is placed adjacent the product type listed in the coupon list to identify the product as having a discount. When the product is moved through the checkout station (20), the manufacturer and product type is obtained off the product by a scanner (40) and compared to the local coupon list by a coupon comparator (46).
