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 IDENTIFICATION
MODULE
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.
FEATURES
• Built-in fingerprint authentication .
• Various authentication using 1:1/1:N matching and
Password.
• Convenient DK without a connection to PC.
• Accurate authentication ratio even to small-size/wet/dry
fingerprint.
• Fast acquisition of difficult finger types under virtually any
condition.
Economical due to low voltage consumption
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

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 Atmel’s 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
