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

SYSTEM
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
time
•Manage vehicle and people
entry points

SYSTEM
3.Security Access and Control:
•Restricted access by user, location and time of
day.
•Exception report for access to sensitive areas

SYSTEM
Tool & Resource :
SOFTWARES:
• PROTEUS VERSION 7.0
•KEIL version 4.0
•TOPWIN 6.0
•EXPRESS PCB
HARDWARES:
•Breadboard
•Power supply
•8051 microcontroller
•L293D IC
•MAX232 IC
•RS232 ports
•RFID transmitter and receiver
•motor
•printed circuit board
•Wires and Solder

SYSTEM
Concept used :
8051 Microcontroller:
•A 8051 microcontroller have
4 ports and each ports
Having 8 pins.
•It is 40 pins IC
•4k ROM(on chip program
Space in bytes)
•128 bytes RAM
•2 Timers
•32 I/O pins
•1 serial ports
•6 Interrupts sources

11
SYSTEM
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.

12
SYSTEM
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.

13
SYSTEM
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.

14
SYSTEM
LCD:
•It able to display numbers
characters, and graphics.
•It has 14 pin

16
SYSTEM
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.

17
SYSTEM
•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.

SYSTEM
Application:
•Security Purpose
•Unauthorized Access Control
•Automated database updation

20
SYSTEM
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.

21
SYSTEM
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.

SYSTEM
Future aspects:
 Fpga based access control system
Vision control access systems
