First of all, one of the challenges facing sales staff at stores is securing time to serve customers. Due to the nature of the product, customer service requires specialized skills and time. There is a need to reduce the burden of operations such as inventory. Expectations for the introduction of RFID are also increasing from the standpoint of brand protection. The prevalence of counterfeit products, especially online, poor brand value and reputation, leading to economic losses. Management of the supply chain is important. Improving inventory accuracy and visualizing inventory are also major issues. We must promote optimization of inventory levels from the standpoint of controlling excess inventory while maintaining a system that allows consumers to purchase what they want anytime, anywhere, regardless of sales channels such as stores or online.
