IoT RFID Lock Door Security System

Abstract

Wireless security system is widely used and favored by many industries, leading to mass growth of this technology. Prior to that, many advancement has been made throughout the decades. One of the popular wireless security systems is the Radio Frequency Identification System or RFID. RFID is favored over other systems due to myriads of its application in current systems like ATM cards, national ID card, toll system, parking lot system, and even mobile phones. This paper proposes an improved design of an RFID security system utilizing a Wi-Fi capable microcontroller (ESP-8266/ESP-12E). Combining the RFID system with an IoT system shall provide user with maximum control and monitor over the system. In this system, a RFID module (MCRF522) and an ESP-12E are used to identify a RFID card UID, in which a relay will turn on if the card is authorized, and the otherwise if not. The information will then be transmitted over the internet to a database, in which the information will be accessible via an app created specifically for the system for flexible configuration by the host user.
