Energizing ATM Security by Sending OTP to Aadhar Card-Linked Mobile Number and Using Fingerprint

Abstract

ATMs are utilized by everyone to withdraw and transfer money in today's environment. The implementation of fingerprint mechanisms in the ATM system served as the basis for this study. We chose this location in order to make transactions easier and safer for all clients. Each person's fingerprints have unique minute characteristics. You don't have to have your ATM card with you at all times, and you don't have to worry about losing it. It is shown that fingerprint technology outperforms and is safer than other technologies when compared to other technologies used for ATM security. It makes transactions simple and safe while preserving an environment that is easy to use for both users and ATMs. When it comes to electronic money transactions, this technology is the most promising. Sending OTP to Aadhaar-linked Phone Number. Aadhaar Linking: The user must have their mobile number linked to their Aadhaar card for this process to work. This number is stored in the bank’s system as part of their KYC (Know Your Customer) records.  OTP Generation: After fingerprint authentication, the ATM will trigger the bank’s system to generate a one-time password (OTP). SMS Delivery: The generated OTP is then sent via SMS to the mobile phone number linked with the user’s Aadhaar account.
