Medical equipment manufacturers, mainly orthopedics, use only a part of the product group delivered according to the surgery, such as long-term rental, short-term rental, purchase, etc., unlike the sales format of general companies. The unused product group is returned to each manufacturer, and after replenishing the shortage, it is shipped again, repeating the cycle. Inspections and sales recording at manufacturers, distributors, dealers, and hospitals place a heavy burden on human workers, and　the use of RFID has begun to be considered as a way for labor-saving. From the perspective of medical quality, safety, and business feasibility such as economic efficiency and profitability, we will deliver high-level medical care to patients by delivering products that are needed at the right time. It is also expected to prevent medical errors by providing it, and by scrutinizing unnecessary items and reducing purchases, we can contribute to the soundness of hospital management.
