RFID Based ATM Security System Using IOT

The technology is increasing in leaps and bounds in the present era. With many technical developments and advances taking place, there has been an advancing trend in the techniques of handling money, money transaction and exchange methods. The Automatic Teller Machine (ATM) is the most widely used method to withdraw money and get bank statements. In the era where there are a wide range of banking companies being established, the usage of ATM cards has increased drastically. ATMs of different banks in every locality and almost thousands of people use them to withdraw money every day. As every coin has two sides, no doubt that ATMs has made the withdrawal of money much easier and reliable, yet there are major challenges to this money withdrawal process. Nowadays people have multiple bank accounts and every bank has the ATM card associated with it. In addition to this, for every ATM card there is a unique pin associated with it. Hence, it becomes a cumbersome task to handle so many ATM cards which involve so many passwords and pins. Apart from this disadvantage there is yet another greater risk that is theft of the Atm cards or losing or misplacing them. Though there is Pin associated with an ATM card which serves as security, it is quite possible to crack the PIN of it. Hence, we have come up with the solution, a card which integrates all the bank accounts into a single card which makes withdrawal of money much more easy, feasible and secure. The additional security features such as fingerprint verification and two factor authentication provide protection against identity theft during the money transactions from ATMs. This system with advanced security features would have many features which would solve various disadvantages associated with ATM systems present today. We have used fingerprint sensor, GSM module, RFID to provide two factor authentication for the ATM system.
