RFID BASED BANKING SYSTEM


RFID BASED BANKING SYSTEM
Objective:
                  The objective of this project is to improve the security performance in the bank by using RFID card.
Scope:
               This project is very used to improve the security performance in the bank. In this project RFID card is used as bank pass book or ATM card. Now day’s some person makes the duplicate ATM card. But in this project RFID card is used for accessing the banking applications. So this project improves the security performance because we cannot make the duplicate RFID card.   
Brief methodology:
             This project is designed with
Ø  RFID tag
Ø  RFID reader
Ø  Microcontroller
Ø  RS 232 converter
Ø  Driver circuit
Ø  Alarm
Ø  PC
Ø  Key pad
RFID is the special type wireless card which has inbuilt the embedded chip along with loop antenna. The inbuilt embedded chip represents the 12 digit card number. 
            RFID reader is the circuit which generates 125KHZ magnetic signal. This magnetic signal is transmitted by the loop antenna connected along with this circuit which is used to read the RFID card number.
  In this project RFID card is used as bank pass book or ATM card. So each customer has the individual RFID card which represents the bank ID number. RFID reader is interfaced with microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we already programmed with card number. The microcontroller is interfaced with PC through RS 232 converter. The RS232 is used to convert TTL logic to RS 232 logic.
                     When the customer shows the RFID card in the reader, the reader will read the number and send to microcontroller. Then the customer has to press the personal identification number through key pad.  The microcontroller received the card number from the reader compares the stored number if the card is valid the microcontroller    transfers the card information to PC. Through PC we can access the banking application such as saving, withdraw, balance enquiry etc.
.   If the RFID card is not valid for that particular customer, the 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.
Advantage:
1.      Low power consumption
2.      We can access the banking application easily.
3.      Improve security performance in the bank because we cannot make the duplicate RFID card.
Application: 
                 This project is very useful to the every bank.
