7. Why fingerprint biometric:
High Universality
High Distinctiveness
High Permanence
High Performance
High Acceptability
8. Fingerprint pattern:
Loops:
Ridge lines enter from one side and curve around to
exit from the same side.
60-65%of population.
Whorls:
Rounded and circular ridge pattern.
30-35% of population.
Arches:
Ridge lines enter from one side print and exit out the
other
5% population

11. Power Supply:
Most digital logic circuits and processors need a 5
volt power supply.
we use a LM7805 voltage regulator IC.
12. Fingerprint scanner:
A fingerprint sensor is an electronic device used to
capture a digital image of the fingerprint pattern.
13. MAX 232
To connect any RS-232 to a microcontroller
converters such as MAX232 is used.
Bit 1 for -3v to -25v
Bit 0 for +3v to +25v
Buzzer:
Informs when any unauthorized
person.
14. Microcontroller
A Micro controller consists of a powerful CPU tightly coupled
with memory RAM, ROM or EPROM),
various I / O features such as Serial ports, Parallel Ports,
Timer/Counters, Interrupt Controller, Data Acquisition
interfaces-Analog to Digital Converter (ADC), Digital to
Analog Converter (ADC), everything integrated onto a single
Silicon Chip.
15. Key pad:
We are using two types of keypads
The matrix keypad and
other is the normal key for selecting the mode of
operation.
LCD:
Output device
Clearly displayed on the LCD.
16. Locker system:
DC motor as the Locker for the authorized persons in
the Locker system mode.
EEPROM:
This is the additional memory which we are using for
the storage of the data for a particular person.
17. Working process:
If a person enters in an ATM/Bank,he has to scan his
fingerprint. If it matches ,he goes for transactions.
Otherwise if any unauthorized
person enters then alarm sound will be
Heard from buzzer.
19. Future Scope
Performance can be increased in terms of speed and
memory.
A speaking voice alarm can be used to indicate
unauthorized person accessing the ATM.
The system can be made to communicate with
modems or mobile phones
20. Conclusion:
The microcontroller based system for securing the
transactions of the user and providing the security for
the locker system and even more for the PASSPORT
verification using a finger print scanner has been
followed.
