CHICAGO — SmartShop, a kiosk system that offers shoppers customized discounts on frequently purchased products, has been implemented by three Shop ’n Save stores in the Pittsburgh area, as well as three Foodtown stores in New York and New Jersey, San Francisco-based Pay By Touch announced this week. The announcement was made at the Food Marketing Institute Show/Marketechnics here. The stores are the first to use a card-based version of SmartShop, which was designed as a biometrics-based system. These merchants will migrate to the biometric version of SmartShop, and adopt Pay By Touch’s biometric payment solution, allowing shoppers to identify themselves, pay for purchases and redeem rewards via a fingerscan. Until then, when shoppers enter the store, they scan their loyalty card at the kiosk to get personalized offers based on their purchase history. “We are extremely pleased with the SmartShop service, which is branded ‘Shop ’n Save Personalized Perks’ in three of our Pittsburgh-area stores,” said Greg Hartley, owner of three Shop ’n Save locations, in a statement. “The service is a huge hit with our shoppers, with kiosks in each store receiving more than 300 visits a day.”
