In this project, we will introduce you to the Automatic Smart Toll Tax Collection System designed using RFID Module and Arduino. Nowadays there is a huge rush in toll plazas for paying the toll tax. Therefore, in order to reduce traffic and save time, an automatic toll collector can be used. The aim of the project is to automatically identify the RFID tag in a vehicle and to display the particular amount the user has to pay in order to pass the toll. If the user pays the amount, he can pass the gate else he will be blocked.
This project is a demo of a Smart Toll Tax Collection System. Consider there are n numbers of vehicles at Toll Plaza. When these vehicles cross the IR Sensor, the gate will be closed. At the same time, the LCD will display to put the Card to the reader for scanning. Then you can put your card on RFID and pay your bill. When the bill is successfully paid, then you can go towards the 2nd Gate. When a vehicle crosses the 2nd IR Sensor, the gate will be opened and you can go. In case the card doesn’t have a balance, you can recharge the card using this RFID and Keypad by entering the amount.
Thus this RFID Based Toll Tax Collection System can be used for Industrial applications.
