ABSTRACT
The Main objective of this project is to
authenticate and to maintain attendance by
collecting fingerprints using fingerprint
sensors. Nowadays accurate personal
identification is becoming more and more
important. Usual means (smart cards, passwords)
have shown their limits. Currently fingerprint
recognition is the most widely used technique for
personal identification. The use of ink and
paper to get an image from a finger was used for
a long time, but technological advances have
enabled to automate the acquisition stage by
means of solid-state sensors. These sensors
exploit different techniques to acquire the image
(pressure, electrical field, temperature) and
require a static (matrix sensor) or mobile finger
position (sweeping mode sensor). The project
is developed with 3 level securities, i.e. to
provide the authentication here an ID, password
and finger print are required. The project
contains 2 modes, the first one is master mode
and the second is user mode.

The fingerprint sensor sense the thumb impression
of the particular person and that image will be
registered with username and password in
fingerprint sensor module. This project is
developed on microcontroller (89S52). The
fingerprint sensor is serially interfaced to the
microcontroller via MAX232 IC. The fingerprint
sensor sense the thumb impression of the
corresponding person and that image will be
compared with registered image and if the both
images are unique, then the microcontroller
activates particular task like authenticating an
image, identification of the employee etc which
also maintains the attendance record of each and
every employee. The process of authentication
is done by entering username and password by
using a keypad.

FINGER PRINT SENSOR FIM10 is a
stand-alone Fingerprint Recognition Device with
many excellent features. It provides the high
recognition performance, the low power
dissipation and the RS-232 serial interface with
the simple protocol for easy integration into a
wide range of applications. It is a durable and
compactable device and made into a fingerprint
recognition module with NITGEN optics-based
fingerprint sensor.

Fingerprint Identification Module) is an
evolutionary standalone fingerprint recognition
module consisted of optic sensor and processing
board. Its voltage is so low(3.3V) enough to
implement a series of 23,000 authentication
consuming 4 piece of AA batteries and executes
average 1.2 seconds of high speed authentication.
As CPU and highly upgraded algorithm are embedded
into a module, it provides high recognition ratio
even to small-size, wet, dry, calloused
fingerprint. Due to technologies of simple and
robust hardware design and including keypad
function of the existed DK in one board, it can
be executed to develop viable applications and
perform user enrollment and authentication needed
for fingerprint recognition without a connection
to PC.

MAX 232

• 1. The MAX232 is a dual driver/receiver that
  includes a capacitive voltage generator to supply
  EIA-232 voltage levels from a single 5-V
  supply.
• 2. Each receiver converts EIA-232 inputs to 5-V
  TTL/CMOS levels.
• 3. These receivers have a typical threshold of
  1.3 V and a typical hysteresis of 0.5 V, and can
  accept 30- V inputs.
• 4. Each driver converts TTL/CMOS input levels
  into EIA-232 levels. The driver, receiver, and
  voltage- generator function

• Operate Up to 120 kbit/s
• Two Drivers and Two Receivers
• Low Supply Current . . . 8 mA Typical
• Designed to be Interchangeable With
• Maxim MAX232
• 30-V Input Levels

MICRO CONTROLLER 89S52

• The AT89C52 is a low-power, high-performance
  CMOS 8-bit microcomputer with 8K
• bytes of Flash programmable and erasable read
  only memory (PEROM). The device
• is manufactured using Atmels high-density
  nonvolatile memory technology and is
• compatible with the industry-standard 80C51 and
  80C52 instruction set and pinout.
• The on-chip Flash allows the program memory to be
  reprogrammed in-system or by a
• conventional nonvolatile memory programmer. By
  combining a versatile 8-bit CPU
• with Flash on a monolithic chip, the Atmel
  AT89C52 is a powerful microcomputer
• which provides a highly-flexible and
  cost-effective solution to many embedded control

LCD DISPLAY

• Liquid crystal displays (LCDs) have materials
  which combine the properties of both liquids and
  crystals. Rather than having a melting point,
  they have a temperature range within which the
  molecules are almost as mobile as they would be
  in a liquid, but are grouped together in an
  ordered form similar to a crystal.
• An LCD consists of two glass
  panels, with the liquid crystal material sand
  witched in between them. The inner surface of the
  glass plates are coated with transparent
  electrodes which define the character, symbols or
  patterns to be displayed polymeric layers are
  present in between the electrodes and the liquid
  crystal, which makes the liquid crystal molecules
  to maintain a defined orientation angle
