Implementation of a User-Friendly Radio Frequency Identification and Password-Enabled Security Access System

Abstract

Due to the prevailing security concerns in recent times, and the costliness of sophisticated security access systems
that require cutting-edge technologies, this paper presents a low-cost design security access system. The design implements a user-friendly Radio Frequency Identification (RFID) and password-enabled security access system to tackle the escalating security threats in homes and industrial outlets. The system components include an RFID reader and card, a matrix keypad, a microcontroller, a buzzer, an LCD, a motor driver, and a low-cost power supply unit. These components are interfaced with the microcontroller, which serves as the central processing unit (CPU) of the security access system. The security system circuit was designed using Proteus – a virtual laboratory and programmed using CloudX C programming language. The system was configured such that it provides higher security measures with the two-level security authentication systems incorporated. The complete design is a low-cost and independent security access system powered by 12V mains. The system was tested against standard metrics, and the results show that it allows access to authorized individuals wholly, but only denied access to unauthorized parties.
