- 2. INTRODUCTION • This project is designed for electronic voting machine by using the fingerprint identification method. • Here voters thumb impressions are used for identifying the voters. • During voting when the voter keeps his/her thumb in the scanner, the system will check whether it matches with pre stored impressions in the database. • If it matches then system will allow the voter to poll his vote and otherwise prevent the voter from polling.
- 3. Why only Fingerprint ? • Every person in this universe has unique fingerprint. • Fingerprints are unique i.e. everyone is born with one, which states that fingerprints can be used for unique identification. • Fingerprint scanner is a device for computer Security featuring superior performance, accuracy, durability based on unique NITGEN Fingerprint BiometricTechnology. • Fingerprints tech is widely used in banking, authentication etc… • Reliable and trusted Hence we opted for fingerprint technology in our project.

- 7. Microcontroller (AT89S52) • A Micro controller development of reduces PCB size & cost of design . • If a system is developed with a microprocessor, the designer has to go for external memory such as RAM, ROM, EPROM and peripherals. • Which is Because it has 8 Kb on chip flash memory use sufficient for our application. • Moreover ATMEL is the leader in flash technology in today’s market place and hence using AT 89S52 is the optimal solution.
- 8. MAX 232 • It is 16-Pin IC known asVoltageConverter or Line Converter. • It converts the RS-232 levels of the Fingerprint Scanner to theTTL voltage levels of µC 8051. • MAX Maxim Company 232 Series number • RS Recommended Standard was set by the Electronic Industries Association (EIA) in 1960. • Using DB-9 (Data Bit) Pin connector, we’ll connect the MAX-232 to the Fingerprint Scanner. • We can connect two devices at a time to the MAX-232.
- 10. Features of AT89S52 : • The AT89S52 is a low-power, high-performanceCMOS 8-bit microcontroller. • 4.0V to 5.5V Operating Range • Fully Static Operation: 0 Hz to 33 MHz • 256 x 8-bit Internal RAM • 32 Programmable I/O Lines • Three 16-bitTimer/Counters • Eight Interrupt Sources • Low-power Idle and Power-down Modes • Fast ProgrammingTime
- 11. Pin Description :
- 12. Fingerprint Scanner (NITGEN FIM 3030) • The fingerprint scanner used here is NITGEN company based which is the leading manufacturer of FIM(Finger identification Module) • The methodology involves of storing the fingerprint images as database and during voting the input image is matched using the database
- 13. LIQUID CRYSTAL DISPLAY(LCD) • The LCD display is used to display the messages during the action. • Here a 16x2 display is used, each character is made of 5x7 dot matrix. • Displays have built in backlight(blue or green diodes)

- 16. ADVANTAGES • Low power consumption • It is economical • Less manpower required • Time conscious, as less time required for voting and counting • Avoids invalid voting. • Saves transportation cost due to its compact size. • Convenient on the part of voter.
- 17. • EVM are no different than websites or software; they can be penetrated and altered by a hacker. • Overall cost is high, physical tampering could be possible. • Computer software and systems can have problems that may delay or even halt voting. DISADVANTAGES OF EVM
- 18. LIMITATIONS • The limitations of this projects are: • The collection of fingerprints of all the voters is little difficult. • Only fingerprints of the voters is identified instead of identifying the persons
- 19. Conclusion • The project “ELECTRONIC VOTING MACHINE USING FINGERPRINT Tech” has been successfully designed and tested. • This can bring a revolutionary change in the election procedures. • It provide additional security. • System completely reduces the chance of invalid votes. • The system can be manufactured simply as well as cheap.
