Time registration is executed in the following manner: when the employees enter or exit the company, they place the proximity card near 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 was 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 into the controller's internal memory. Because its capacity is limited, the user must make sure that the data is transmitted in due time, otherwise a portion of the collected and registered data may be deleted.
The most important part of the system is the software which enables entering cards and modifying employee data, setting time phrases, reviewing the registered data, correcting data, arranging printouts according to various criteria, entering and changing time phrases ... 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 more demanding environments in terms of technology and personnel a web interface may be used, which enables the employees to review their data and the administrators to work with the program from remote locations.
