Automatic fuel dispensing with payment gateway

Abstract

Fuel dispensing systems with payment gateways provide a comprehensive solution for managing fuel transactions at filling stations. The system integrates a fuel dispenser with a payment gateway, allowing customers to purchase fuel using various payment methods such as credit/debit cards, mobile wallets, and cash. The payment gateway integrates with the fuel dispenser to securely process payments, while the dispenser measures and dispenses the fuel. The system also features real-time monitoring of fuel transactions, inventory management, and reporting capabilities, enabling station owners to effectively manage their business operations. An ESP32 microcontroller is interfaced with a designed web-based software that was used in controlling the process of fueling with the aid of an LCD, a keypad, and customized RFID cards to help identify users and interface with the system. Additionally, the system ensures that all transactions are recorded and accounted for reducing the risk of fraud and errors.
