The top three retailers by revenue are Walmart at $421.8 billion, Carrefour at $120.3 billion, and Tesco at $94.2 billion. In contrast, there are over 1 million local shops in the Benelux region alone. The document then discusses how mobile technologies can help local shops communicate on mobile platforms, create mobile websites, and acquire and upsell customers through geolocation services. It argues that local shops are more flexible than supermarkets and can benefit customers who are increasingly mobile by updating their information in real time through APIs.
