RFID Based Security Access Control System with GSM Technology

Abstract

The security challenges being encountered in many places today require electronic means of controlling access to secured premises in addition to the available security personnel. Various technologies were used in different forms to solve these challenges. The Radio Frequency Identification (RFID) Based Access Control Security system with GSM technology presented in this work helps to prevent unauthorized access to controlled environments (secured premises). This is achieved mainly through the use of a Radio Frequency Identification System with operating frequency of 125 KHz, Microcontroller programmed to send control signals, Liquid Crystal Display (LCD) and GSM. If any concerned person need to access the data, from RFID he has to get an verified access by the AUTHORISED person. By using RFID tag in which the data is been stored is brought in a range of RFID reader, once he detect the RFID tag then GSM sends the one time password (OTP) to the authorized person’s mobile. once if he give the OTP through KEYPAD to the LPC2148 ARM 7’s microcontroller. It will give access to the data stored in the RFID by displaying it on the LCD 20*4. buzzer turns ON for about 5seconds and GSM modem been activated to send UNAUTHORIZED, invalid user’s to the security personnel. The electronic circuit was implemented, the codes for microcontroller were written in embedded C, debugged and compiled using the KEIL Micro vision 4 integrated development environment. The resultant Hex files were programmed into the memories of the microcontrollers with the aid of a universal programmer. Hardware simulation was carried out using the Proteus Virtual System Modelling (VSM) version 8.0.An importation implication of this paper is that the system is cheaper to maintain and more efficient in comparison with a manually operated type or key lock system. The RFID based access control system can be useful in providing security for medical organization, homes, organizations, and automobile terminals to increase the level of security.
