Hi I'm Mounika ,why the project name is unmanned petrol bunk system and every task is done by men like swiping card, pumping petrol in to vehicles, typing on the key board ,the main aim of the project is unmanned but the hole task is done by a man

advantages of unmanned petrol bunk system using smart card
Abstract
Today almost all petrol pumps have a micro controller to control the electrical pump, drive the display, measure the flow & accordingly turn OFF the electrical pump. But still a person is required to collect the money. Our project is designed to eliminate this human interaction so that there is no need of workers to fill the petrol.
In general, a smart card is an integrated circuit card with memory capable of making decisions. This project can be used for recording the attendance of an employee in an organization or a student in a class.
A smart card, chip card or integrated circuit card (ICC), is defined as any pocket-sized card with embedded integrated circuits which can process information. This implies that it can receive input which is processed by way of the ICC applications and delivered as an output. In this project, we are using a contact smart card where the information inside the card is communicated with the card reader by inserting card into the card reader. The card reader in this project used is an SR-90 SDK of 1KB memory size.
The smart card reader contains a PIC 16F73 microcontroller, a voltage regulator, serial cable connections, and an LED which glows whenever a card is inserted into the reader and also it glows whenever it issues any command or receives any command. The Smart Card Reader is interfaced with the microcontroller through serial interface.
In this system, all drivers have a smart card called just like a petrocard. This card can be recharged by some recharge points. The petrol pump is equipped with a smart card reader/write. At the Petrol Pump, the driver swaps the card and the smart card reader reads the amount in the card and will display it on the LCD. The driver then enters the quantity of petrol that has to be filled using a keypad. The corresponding amount is calculated & deducted from his petrocard. The electrical pump is then turned ON according to the entered amount, fills the tank and automatically turns OFF.
