Coupons Inc. is printing coupons with GS1 DataBar barcodes, which provide more information than UPC/EAN barcodes. Due to the ability of the GS1 DataBar to track customer compliance with the offer and vary the value of the coupon to a greater extent, it is expected to become the industry standard on all manufacturer's coupons over the next two years. L'Oreal and White Wave Foods have already adopted the GS1 barcode.
