Time and attendance registration is performed in the following manner: when employees enter or exit the company, they bring the proximity card to the time and attendance controller. When registering special events, they must first press the appropriate function button on the controller. The text shown on the controller's display enables the employee to immediately check whether the event has been correctly registered.
The registered data is transmitted onto a computer, which is connected with the controller through a communications converter. If the client also uses access control system, the time and attendance controller (or several such controllers) may be included into the existing communications line as an additional controller.
The data is transmitted to a computer every time there is a connection established between the computer and the controller - always or occasionally. When the connection is not established, the registered data is saved in the controller's internal memory. Because its capacity is limited, the user must make sure that the data is transmitted in good time; otherwise there is a risk that part of the collected and registered data may be deleted.
The most important part of the system is the software which enables the entry of cards and modification of employee data, setting of time phrases, reviewing of registered data, the correction of data, arranging of printouts according to various criteria and the entry and changing of time phrases e.t.c. The data should be arranged by an authorized person (an administrator). If there are more administrators or they work in various locations, the system may be upgraded with net versions of the program (clients). In the more challenging technological and human resources environments we can also upgrade the system with a web interface that enables employees to review their data and administrators to work with the program even from remote locations.
