In recent years, with the development of sensor card technology and biometric technology,the access control system has been developed rapidly, and the product form and application mode have diversified development trend. From induction card access control system to mobile access control system, now they all have their own special features in the fields of safety, convenience, manageability, etc. The application of access control system is also more and more extensive.

Although access control products and technologies have been updated in iterations, users have been carrying only about 30% of the functions of the access control system itself. In the change of the innovation function of the access control system, more lies in the evolution of the way of access control and human connection.

There are several phases, such as followings

Mechanical locks, the most traditional and most widely used single door lock. The user only needs to pass the corresponding key to complete the opening and closing of the door. There is no need to do a large number of personnel in and out of the statistical management only play the security role in the family, the general community.

Access control of reading card can recognize access rights by reading card. Access control system for reading card application goes well beyond a single doorway and key management which gradually developed into a set of complete access control management system. It also plays an important role in the working environment safety and personnel attendance management.

The rise of intelligent access control makes the access control system have more application modes. Mobile phones are a new way to identify, and provide a feasible solution for remote door opening. Intelligent access control is the extension and breakthrough of traditional access control, and it is the main direction of the change of the access control system in the next stage.

From mechanical lock to intelligent access control system, each kind of access control system has its advantages and disadvantages, along with the application requirement of user groups, these kinds of access control system all have their respective market areas.
