Pay-by-Palm: A Contactless Payment System

Current payment systems, including cash, credit cards, and UPI can be inconvenient for users, prompting the need for a more robust and user-friendly payment system. Biometric authentication methods like palm prints can enhance security and the user experience, but there is a lack of a reliable system that integrates palm print recognition with e-wallets to facilitate payments at participating merchants. Existing payment systems fail to provide a secure and convenient way to pay using palm prints, with challenges regarding the accuracy, reliability, and privacy of palm print recognition technology. By integrating palm print recognition technology with e-wallets, this work aims to meet the growing demand for a more advanced payment system that enhances the user experience while providing a secure way to make payments.
