SMART AND SECURED SINGLE ATM CARD WITH MULTIPLE BANK ACCOUNTS

ABSTRACT:- This project’s main objective is to integrate multiple bank accounts into one single smart card. Many bank charges ATM usage fees from the customers for different transactions. At present day, every customer has an individual ATM card for each and every bank in which he/she maintains account. So, while handling the cards, many passwords are involved. In order to overcome these difficulties, we embedded more than one bank account of the user in a single ATM smart card, therefore letting the user to swipe the card so that the respective individual can select the bank from which he/she is interested to carry
out transaction. The final outcome of the system consists of Arduino Mega, RFID tag, RFID reader, GSM module, 16x2 LCD display, servo motor, keypad, buzzer and finger print sensor. The magnetic strip-based ATM card is replaced with
RFID based card which have a unique number. The Arduino MEGA
microcontroller is used to process the data from the sensor. A 4x4 keypad is connected to the microcontroller that acts
as an input to enter the 4- digit pin. The finger print of the user is verified using an optical fingerprint reader, if the fingerprint does not match, the buzzer starts ringing. Finally, irrespective of success or failure of the transaction a message or call is sent to the user through GSM module (SIM800L) which is 2G based network.
