At the stores, users first use a dedicated app to scan a QR code upon entering the store. They read the barcode of the item they wish to purchase with their own smartphone and pay with a credit card or other payment method. There is no need to stop at a cash register. The stores will be operated by a single employee, who will be responsible for tasks such as stocking products and ordering. The store will have an area of approximately 50 square meters, much smaller than a conventional store's 200 square meters. In addition to rice balls and bread, chilled boxed lunches, daily necessities, and freshly brewed coffee will be available. The number of products will be reduced to a maximum of 1,200, less than half the usual number. The convenience store market in Japan is saturated with nearly 56,000 stores. Small unmanned stores will increase the room for new openings and improve customer convenience by eliminating wait times at the cash register.
