Design and implementation of a system access control by RFID

We present the design and implementation of a system access control using radio frequency identification (RFID) controlled by Arduino platform. The proposed system consists of a radio frequency reader (RC522), a set passive tags (identification cards), microcontroller Arduino MEGA, and graphical user interface (GUI) implemented in Matlab
^®
. Through a GUI, it is possible to take control of access to the building and check the assistance; using identification cards, the user is able to access information of authorized personal. With this system is possible supervise, manage and report all personnel access.
