or Credit Card or at some points there may be Bank Note payment (Cash) by automatic machines, Following are some functional requirements: There will be automatic gate that will not allow owners to take their vehicles if they didn't make the payment. Provide detailed system analysis and possible interaction design that will help to execute the same for petroleum companies. Your design should also contain suitable diagrams.

System Analysis:

• To get this facility, we can use one application which should handle all types of payment modes and this should be connected to electronic circuit which could handle the opening of a gate and closing of a gate for vehicle at petroleum pump center.

• In this we can use an electronic which can only get opened which we use a payment receipt (its bar-code) at door sensor, once a door get opened a vehicle can leave pump center.

• If an user doesn't make a payment, he/she will not get receipt and without receipt a door will not get opened, also if one will try to open a door, without receipt bar-code, an alarm sensor will get played and security guards will come.

• A detailed system analysis can be effectively shown using flowchart.

Design:

This interface is used while filling a petrol at petrol pump.

This interface is used to select payment mode.

This interface is used to enter card details for cashless payment.

This interface is used to show payment acknowledgement.

This interface is used to be scanned to open exit door.
