This document describes an RFID-based secured access system created by students. The system uses an AT89C51 microcontroller, RFID reader, LCD display, and keypad. It is designed to only grant access to authorized individuals by verifying both the RFID tag number and entered password. The system could be applied to applications requiring high security like homes, government offices, and defense areas to automate door locks. It provides a cheap alternative to traditional security systems.

3.  To design and implement an RFID based secured
access system, so that it can be implemented in many
applications like secured access in houses,government
and defense offices where high security is required
automated door lock system etc.
 To grant access to only authorized representative by
verifying RFID tag number and the entered password.

Objectives

4.  The project is mainly focused on developing a
microcontroller based system to grant access only
to authentic representatives and deny to
unauthorized.
 The project is built around AT89C51 architecture
based microcontroller along with a RFID Reader,
LCD and a keypad.

microcontroller IC
Protel 99 To Create PCB Layout
2.Software

13. • This control system can be used in many applications
like home automated system, automated door lock
system,safe bank locker systems etc.
• It provides a cheap and reliable security alternative for
traditional systems available.

Advantages

14.  This control system can be used accordingly as in many applications by
making small changes in the hardware as well as software.
 It can used in home automation,where a GSM module along with a
SIM can be interfaced and a message can be sent to the owner making
him aware about intrusion in the house.
 Some software and hardware changes in such a way that the stepper
motor will be interfaced and it will only move until and unless correct
password is given then this type of system can act as a Automated
Door Lock System.
 This System can be made more secure by adding another layer of
security in the form of iris scan,biometrics etc. to develop a full-proof
system.

Applications

15.  This system can be useful in reducing risks involved in
security related problem areas either in
houses,government offices,Defence related areas.
 Thus,we have designed and implemented an
“RFID BASED SECURED ACCESS SYSTEM”
efficiently and have achieved our motto.
