What is Biometrics?• The study of automated identification, by use of
physical or behavioral traits.

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
other5% population

Power Supply:
Most digital logic circuits and processors need a 5 volt power supply.
we use a LM7805 voltage regulator IC.

Fingerprint scanner:
A fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern.

MAX 232
To connect any RS-232 to a microcontroller converters such as MAX232 is used.
Bit 1 for -3v to -25vBit 0 for +3v to +25v
Buzzer: Informs when any unauthorized
person.

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.

Key pad:
We are using two types of keypadsThe matrix keypad and other is the normal key for selecting the mode of
operation.
LCD:Output device
Clearly displayed on the LCD.

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.

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.

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

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.
