AI-powered smart carts are emerging as a potential “killer app” for supermarkets and grocery stores to revolutionise the shopping experience and regain market share lost to other retail formats. With grocery store market share dropping from 69.7% in 2017 to 66.6% in 2022, these smart carts present an opportunity to enhance customer engagement and convenience while reducing friction in the shopping process. The average consumer shops for groceries about eight times per month, facing rising costs and around 40 minutes of shopping time. Traditional efforts like buy-online-pickup-in-store (BOPIS) and self-checkout have faced challenges and declining usage. However, smart carts equipped with video displays and innovative features like location-based promotions offer an appealing alternative that benefits both retailers and consumers, potentially transforming the supermarket shopping experience.
