Owing to the lack of determinacy and immediacy in staff management, communications and regulations in a company can not be handled effectually. According to the problem stated, the typical solution is to check the location of every each employee randomly. By doing this, the company can make sure that its staffs are all in proper working places. The importance for staff management is not only for the safety and efficiency of working, but also for the protection of core research achievements for companies. In view of this, the study is focused on improving the convenience of staff management for all divisions in companies. RFID (Radio Frequency Identification) technology is combined with the Cloud technology to find out the exact locations of staffs immediately and smartly. The system is also integrated with a working attendance system, and multi-phase economic benefits are then realized. The integrated system can also be used as precaution schemes or disaster relief systems. The system may track every each individual in the work places right after emergency situation happened.
