In this paper, an efficient, inexpensive, scalable, and ZigBee-based smart authentication and access control system is proposed. The system consists of a central node and remote nodes. The central node holds a database of authorized users and it is mesh-networked to a set of remote nodes which are spread throughout the premises of an enterprise. For each remote node, a Radio Frequency IDentification (RFID) reader is mounted which is used to communicate with the RFID tags. User identification is performed by reading the RFID tag number and authentication is done by means of a password entered by the user through a keypad that resides on the remote node.
