This document describes an RFID-based toll tax collection system. It consists of an RFID reader, RFID tags attached to vehicles, a microcontroller, LCD display, keypad, and motor drive to control the toll gate. When a vehicle with an RFID tag approaches the toll plaza, the RFID reader scans the unique ID on the tag. The microcontroller then processes the payment and opens the gate. This system allows drivers to pay electronically without stopping, reducing congestion. It provides benefits over manual collection such as increased convenience, less operating costs, and improved transaction transparency.
