Enhancing ATM Security: A Smart Approach

Abstract

Typically, in ATM transactions, unauthorized individuals can easily withdraw cash merely by obtaining someone's PIN. To bolster the security of transactions and ensure they occur under the account holder's knowledge and consent, we've implemented RF readers for authentication. Our system is equipped with a centralized database containing the RFID of each individual, accompanied by their photograph for verification purposes. When a person presents their RF tag to the RF reader, it activates a camera, capturing the cardholder's image. Subsequently, the system conducts a comparison with the database to verify the ID and match it with the individual's facial features. If the facial recognition fails to align with the original card account holder, the system promptly dispatches an image along with an OTP via email to the account holder, signalling an attempted unauthorized use of their ATM. Access to cash withdrawal is granted only upon successful entry of the OTP, thereby thwarting potential fraud. Conversely, if the account holder initiates a transaction, the system recognizes their face from its database and authorizes direct access to withdraw cash from the ATM without necessitating further verification steps. This comprehensive security protocol significantly mitigates the risk of fraudulent ATM transactions, providing account holders with heightened assurance regarding the safeguarding of their funds and personal information.
