This research study describes the ATM with a feature of Iris Recognition for making the ATM more secure. For performing financial transactions, generally, ATM cards are used for authentication but there is a risk of cards getting misplaced or stolen or if the ATM PIN (4- digit Personal Identification Number) is accessed by some unauthorized person, it will enhance the chances of fraud. Hence, biometrics like fingerprint, face recognition, and iris recognition, are used for enhanced security along with ATM PIN. Out of these biometrics, iris recognition is the most effective way as it is more suitable with ages and because of the uniqueness and correctness of different people's iris. This method is more reliable and has a high recognition rate. The False Accept Rate & False Reject Rate are used to assess the effectiveness of ATM system
