This article focuses on the realization of an access control system based on RFID (Radio Frequency by Identification) technology. It is an authentication system for controlling access to a sensitive place. This system is composed of RFID cards which are badges that act as electronic keys, an RFID reader, an electronic lock, a microcontroller, a wifi module and a database installed on a computer. The identification number of an RFID card detected by the RFID reader is transferred, via the serial interface, to the microcontroller that communicates with the computer through the wifi module for verification in the database. If the information is valid, the microcontroller triggers the opening of the electronic lock.
