On the glass badge label, a 2-dimensional code is printed, indicating information such as individual ID, name of the wearer, start and completion dates of the wearing time period etc.
A management system for entering into, and leaving from, the controlled area can be built using this code as a key to identify each person. A reading device for the 2-dimensional code on the badge label is installed at the entrance of the controlled area and an access limit onto person without glass badge is enforced by an automatic door.
Data such as name of persons entered, their time they stayed in the area,can be registered in a time sequence.
