Abstract

Access to sanitary napkins remains a challenge in public and institutional areas due to limited availability and payment constraints. This paper presents an automated, cashless vending machine that exclusively accepts G-Pay transactions, ensuring seamless and hygienic access to menstrual hygiene products. The system is powered by an ESP8266 microcontroller, integrating a QR-based UPI payment system that verifies transactions in real time. Upon successful payment, the vending machine activates a motorized dispensing mechanism, delivering the product efficiently. An LCD display provides users with real-time stock availability, enhancing accessibility and ease of use. The key innovation of this system is its automated payment tracking and refund mechanism by using Google Sheets. By eliminating cash handling, the system enhances hygiene and operational efficiency, making it ideal for schools, workplaces, and healthcare facilities. The scalable design of this vending machine allows for future expansion to other essential products, contributing to a more accessible and digitally integrated vending ecosystem.
