Tesco is preparing for a national rollout of a scheme that uses Clubcard data to target customers with ultra specific deals at the checkout. By generating money-off coupons on till receipts, the initiative enables Tesco to tailor promotions precisely to individual customers when it swipes their loyalty cards at the till. From a manufacturer's point of view, the system rewards consumers for brand loyalty but also serves as an efficient tool for urging them to try new products that match their customer profile, said a spokesman for Dunnhumby, the consultancy helping Tesco develop Clubcard. Significantly, the system is also cheaper than direct mail. It has already undergone extensive trials in stores throughout Wales. {{NEWS }}
