As the importance of information grows, more companies are implementing entrance and exit management systems not only to prevent information leaks but also to keep track of the attendance time of employees. Entrance and exit management makes it possible to manage “when,” “who,” and “where,” as well as ensuring that only authorized persons can enter specific rooms or venues. Murata contributes to the realization of entrance and exit management solutions with general-purpose components as well as sensors for proximity detection, detection of unauthorized access, etc., as well as RFID-related technology of the sort used by “magic strap” systems.
