                  The objective of this project is to improve the security performance in the highly secured areas by using finger print. This project is designed to use the finger print application in the backing system

               This project is very used to improve the security performance in the bank.

In this project finger print is used instead of ATM card and bank pass book. Now day’s some person makes the duplicate ATM card. But in this project human finger print is used for accessing the banking applications. So this project improves the security performance because naturally one human finger print is different from other human.    

                   This project is designed with Microcontroller, Finger print sensor, Arm processor circuit, RS232 and PC.

             Finger print sensor is the special type of sensor which is used to identify the human finger print. Finger print sensor is interfaced with microcontroller through the arm processor circuit. The arm processor circuit is used to activate the finger print sensor at time of finger is placed on the sensor. Then the related data is stored in the microcontroller.

            In this project microcontroller is interfaced with PC through RS 232. The RS232 is used to convert TTL logic to RS 232 logic. The microcontroller transfers the related information to PC. When human places the finger on the finger print sensor, the sensor sends the corresponding data to microcontroller. Here the microcontroller may be Atmel or PIC both are flash type microcontroller in which we have already programmed.

        Microcontroller received the data from the finger print sensor. Then compared with stored data if it is correct the microcontroller sends the corresponding information to PC.  Through PC we accessed the banking application such as saving, withdraw, balance enquiry etc. If data is not matched microcontroller will display the “Authentication Fail “on the LCD display and also activate the driver circuit for alarm.  So the alarm makes the sound for indicating the Authentication Fail.

1.      Low power consumption.

2.      It improves security performance in the highly secured areas compare than others.

    1.  We can use the finger print security system in secured application

2.  We can use in voting machine.

  3.  We can use in house for door open and close etc.
