Carrefour Makes Shopping Easier For Smartwatch, Smartphone Owners

French retailer Carrefour sees a high-tech marketing opportunity among Samsung smartwatch and smartphone customers. The company has partnered with Publicis Shopper and Think&Go to allow Samsung gear S watch and compatible Samsung smartphone owners to access Carrefour shopping lists and loyalty cards using the new C-où mobile app launched last April. Customers create a shopping list on their smartphone and it appears simultaneously on the smartwatch. The new shopping experience, being tested at Carrefour's smart Villeneuve-la-Garenne store, has so far been a hit among Carrefour customers.
