The new convenience store in the city of Yokohama is a joint demonstration project between Japanese prominent electronics producer Panasonic and convenience store mega-chain, "FamilyMart". This experimental project utilizes IoT technology and various data to achieve enhanced operational efficiency for customer. With the latest facial recognition and image analysis technology developed by Panasonic, customers can register their photo and credit card information and then check out using unmanned register. When desired items are put in the center of check out corner, the price is automatically calculated and the money is withdrawn from user's pre-registered credit card. The store is thoroughly equipped with camera and sensor to digitize information in the store. Camera and infrared radiation sensor are installed in the general shopping area to detect customer movement and the number of products on the shelf. Dwell time heat maps are also generated from camera and sensor combined with Smartphone survey and conventional POS data to lead to actionable data. Labor-saving technology has been deployed including automated mobile staff notification system for out of stock product. The information from camera is displayed on screens held by staff member and alerts if certain good is run out. Employee use wearable device which keep them updated with stock information on each shelf. For many products, conventional paper-printed signage and price tag were replaced with digital one for greater work efficiency. Translating devices have also been also introduced. The device instantly provides both audio and written translation of target language over the counter to cater to inbound tourist. Nowadays, filling staff shortage in store is one of the most important tasks for many chains. Behind the scene of developing latest technology, labor shortage is one of the tasks to be solved in society. Through the operation of next-generation store, Panasonic aims to solve societal problem which the retail store industry is confronting today in Japan.
