### **2.1 RFID-based smart petrol station**

Implementation of a smart petrol station system in several countries can be read in many literatures all these projects used RFID tag as a fee card.

In 2016, Punit Gupta, et al. [1] described the design and implementation of a smart fuel station that will calculate the amount of fuel in the petrol station and send the information to a main server. They apply ultrasonic sensor to measure the level of petrol.

In 2016, Gowri Shankar, et al. [2], the proposed Biotelemetry system is used in this research to confirm the singular user with their Petrol tag. Biotelemetry is being employed as a thumbprint sensor in this case.

In 2016, Wavekar Asrar, et al. [3], had the project's major goal is to create a system that uses RFID technology to automatically deduct the amount of gasoline dispensed from a user's card. The use of RFID technology to control fuel dispensing in Indian cities is proposed in this study.

In 2017, Kumaresan and Babu Sundaresan [4] presented paper, it allocates with automation of a petrol station selling outlet; this system will provide the transactions and supply report to the holder for each hour. In this thesis, the user can access the present status of the petrol station as well as the stock maintenance through the net request.

In 2018, Chandana et al. [5], had the goal of this project is to build a security mechanism for filling gasoline at petrol stations without involving humans. The RFID smart card eliminates the risk of carrying cash at all times and also has a prepaid recharging option.

In 2018, Dongarsane et al. [6], had the secure and atomized delivery of gasoline is making possible by the simple and proper use of microcontroller and GSM technologies. It comes with an easy-to-use mobile phone system and a colorful user interface (GUI).

In 2019, Rashmitha [7] suggested a project where the customer has a smart card in this project. The card is nothing unless it has a magnetic member inserted in it. When a consumer presents this tag to the reader, the reader reads the unique number and sends the sign to the microcontroller.

In 2019, Nitha Velayudhan et al. [8], presented study proposes an automated petrol station management system that addresses the shortcomings of the current system. They used GSM and AT Mega 328 to develop an automatic gasoline filling system. This solution has the potential to make the fueling process more convenient, reliable, and secure.

Compared with the projects presented in the above sources, it is clear that our designed project has combined a number of mechanisms used in the construction of a smart fuel filling station. In our project, the researchers used the Arav De card to deal with secure electronic payment. The petroleum card has also been distinguished with a unique number that distinguishes between the type of users and thus controlling the distribution of fuel in Iraqi cities.
