An access system for buildings based on smart cards

Access systems verify and validate accesses made by users to different resources according to some rules. Access systems can be implemented using IT infrastructure. A classical implementation refers to door access in large buildings. Such a system controls and validates the access in the rooms of a building (such as a company, an institution) according to some policies or access rights. This paper presents an access system for a building based on smart cards. Each door is commanded by an access point and all these are connected, through Internet, to a server which will take the decision. The access is requested through a smart card which memorizes the user´s unique identity code.
