AUTOMATIC TOLLGATE CONTROL SYSTEM USING MICROCONTROLLER AND RFID

Abstract

In this project, The RFID tag is used as a unique identity for account of a particular user. First, the user is prompted to scan his tag. The serial code of the tag is identified by the reader module and is sent to ATmega162 for comparison with the stored data. If the identity is matched with the one already stored in the system, the toll amount is deducted from his account and user gets to drive through the plaza. On the contrary, if the tag is not identified ‘INVALID’ is displayed on the LCD screen. If the balance in the user’s account is low ‘PLEASE RECHARGE’ is displayed on LCD screen and the user needs to recharge the RFID card. The purpose of GSM is to alert the user by sending a text message to his personal mobile. If there is low balance in the RFID tag it will alert the user to recharge. If the balance is deducted it will send the balance to the users mobile.
