INTRODUCTION:RFID Access Control use in

three different places

1. Residential Access

Control:•Un-manned access control at

all entry points

•Restrict access by user and by

entry point

•Audit trail of entry point and

time

•Audit trail of exit point and

time

•Manage vehicle and people

entry points

2.Commercial Access

Control:•Un-manned access control at

all entry points

•Control access by company,

employee and visitor

•Restrict access by user and by

entry point

•Audit trail of entry point and

time

•Audit trail of exit point and

Concept used :

8051 Microcontroller:•A 8051 microcontroller have

4 ports and each ports

Having 8 pins.

•It is 40 pins IC

RS232:•To allow compatibility among

data communication equipment.

•It is in DB 25 and DB 9.

•It is most widely used in serial

I/O Interfacing standard.

•The I/O are not TTL compatible,

In RS232 1 is represented by

-3 to-25v ,While a 0 bit is +3 to

+25v ,making -3 to +3 undefined

we must use a voltage converter

such ac MAX232.

MAX232 IC:•It is 14 pin IC.

• A line driver such as the MAX232 chip

is required to convert RS232 voltage

levels to TTL levels, and vice versa

•8051 has two pins that are used

specifically for transferring and receiving

data serially.

•These two pins are called TxD and RxD

and are part of the port 3 group (P3.0 and

P3.1).

•These pins are TTL compatible;

therefore, they require a line driver to

make themRS232 compatible.

L293D:•It is 16 pin IC.

•The L293D device is a

monolithic integrated high

voltage, high current four

channel driver designed to

accept standard DTL &

TTL logic levels & drive

inductive loads(such as

relays solenoids, DC and

stepping motors) and

switching power

transistors.

•It is use as a motor driver.

Working :• Low frequency RFID works on the principle of radio

waves and at the frequency of 125 KHz.

• There is a coil inside the RFID tag and when it is

influenced by magnetic field, it sends an identity code to

a device for further processing.

•The RFID tag is used as an identity for a particular user.

If the identity (serial number of the tag) of the user is

matched with the one already stored in this system, he

gets immediate access through it.

•In beginning, the user is prompted to scan his tag or ID.

The serial code of the tag is identified by the reader

module and is sent to AT89C51 for checking.

•If the ID is matched by the microcontroller, the user

gets the access. On the contrary, if the tag is not

identified, a message (‘Access Denied’) is displayed

on LCD screen.

Advantages:

•An RFID smart card-based system may reduce operation

costs in the long run.

•RFID equipment damage occurs much less frequently

than is the case with magnetic strips or bar codes present

on Charlie Tickets.

Disadvantage:

•In the short run, costs of diffusion and implementation

for an RFID access control system is more.

•Poor read rate can occur if the reader and receiver are not

properly aligned.
