  1. FINGER PRINT ATTENDANCE MANAGEMENT SYSTEM PROJECT MEMBERS: CH.S.ELLARAO (07765A1004) CHIRANJEEVI.N (06761A1012) CH.HARISH REDDY( 06761A1015) PROJECT GUIDE: RAJASEKHAR REDDY.B ME.,

  2. 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.

  3. 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.

  6. FINGER PRINT IDENTIFICATION MODULE

  7. 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.

  8. 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

  9. 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

  10. FEATURES OF MAX 232: • Operate With Single 5-V Power Supply • 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

  11. 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

  12. 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
