Abstract

The conventional method of conducting ATM transactions using physical cards and four-digit PINs presents vulnerabilities such as card theft, PIN observation, and skimming. In response, this paper introduces a novel approach that leverages QR codes for secure and convenient ATM transactions. This system is designed for integration with smartphones and wearable devices, eliminating the need for physical ATM cards. Users generate a unique eight-digit PIN in combination with QR codes for authentication. A dedicated background server manages transactions, generating distinct eight-digit PINs for each transaction while securely linking them to the user's bank account. This approach enhances security, safeguards against observation attacks, and streamlines the transaction process. The innovative system has the potential to provide a more robust and user-friendly alternative to traditional ATM card-based transactions, with a strong focus on security and convenience. However, rigorous testing and adherence to regulatory requirements are essential to ensure its practicality and legal compliance in the banking sector.
