IOT – Enabled ATM

This paper presents an IoT-enabled ATM system designed for accessibility and seamless digital transactions. Built around an ESP32 microcontroller, the system integrates WhatsApp Pay for payments and uses an IR sensor to detect users, triggering voice-assisted instructions for visually or motor-impaired individuals. Users select a predefined amount (₹50, ₹100, ₹200, or ₹500) via a locally hosted webpage, complete the payment via WhatsApp Pay, and receive cash dispensed by a BO motor controlled by an L298N motor driver. Real- time feedback is provided on a 16x2 LCD, and transaction data is logged to Firebase Realtime Database. The system is low-cost, standalone, and user-friendly, making it ideal for individuals with disabilities, small businesses, and rural areas.
