As food delivery services and online shopping disrupt the grocery industry, Kroger is looking to eliminate checkout lanes for busy customers. The Cincinnati-headquartered grocery chain will roll out its “Scan, Bag, Go” service to 400 stores in 2018. Shoppers can avoid long checkout lines by scanning barcodes of items they want to buy using a handheld scanner or through Kroger’s “Scan, Bag, Go” app on any smartphone. When customers are finished shopping, they can stop at a self-checkout to pay for their order. Eventually shoppers will be able to pay through the app instead.
