Abstract
The increasing need for secure and convenient payment methods has fueled the exploration of biometric authentication systems. This paper presents a Biometric Based Payment System designed to streamline transactions while prioritizing security. The system employs a fingerprint sensor (R307) to ensure robust user identification, complemented by a 4x4 keypad for versatile input and an I2C OLED display for clear feedback. At its core, the system leverages an ESP32 microcontroller and robust SHA-256 encryption to protect sensitive information during storage and transmission. Transaction data resides in a centralized MySQL database on an Apache server, and users manage payment history through a web interface. The system emphasizes security and ease of use, with the potential for future exploration of multi-factor authentication, offline capabilities, and blockchain integration to further enhance its robustness
