Mule Joy benefits all parties including customers, sellers and producers. Traditional product display method is replaced by a virtual cart system where customers can add items into cart using their mobile devices. This prevents direct contact between customers and products for sales to avoid shoplifting and viruses like COVID19 from spreading via object contacts. Mule Joy also reports issues of store operation to the sellers in both real-time and aggregated form. In the producer perspective, Mule Joy identifies the target audience for their products via face recognition technology.
