Rfid Based Petrol Pump Automation System

In conventional petrol pump systems, fuel dispensing and billing are carried out manually, which often leads to issues such as fuel theft, human errors, inaccurate billing, and increased waiting time for customers. With the growing demand for automation and secure cashless systems, there is a strong need for an efficient fuel management solution. This paper presents the design and implementation of an RFID-based automated petrol pump system using Arduino UNO, which ensures secure user authentication and accurate fuel dispensing with automatic balance deduction. Each user is provided with an RFID card containing unique identification and prepaid balance INFORMATION. When the card is scanned, the system verifies user credentials, checks available balance, and activates the DC pump accordingly. The pump automatically stops once the predefined fuel amount is dispensed or the balance limit is reached. The proposed system reduces manual intervention, prevents fuel fraud, and improves operational efficiency. Experimental results demonstrate reliable card detection, accurate fuel control, and real-time balance deduction, making the system suitable for modern smart petrol stations.
