ATTCS is an Automatic Toll Tax Collection System. In this paper, the evaluation of the performance of the Automatic Toll Tax Collection System Using RFID is being carried out using JAVA Technology implemented on Net Beans IDE 8.0 and My SQL Database. The automatic toll tax collection system also carries its Wampserver Connection and mailing SMTP protocol. The automatic toll tax collection system is used for collecting the toll tax automatically that helps in reducing the heavy congestions and avoiding traffics caused in the metropolitan cities toll plaza. For this, we provide a particular RFID tag for each vehicle whether a person buys a new vehicle or have a there existing vehicle. The particular RFID tag has its own unique identification number assigned which stores various information in there database server like username, password, address, email, mobile number, vehicle number and prepaid account. Whenever the vehicle has to pass the toll plaza then it must have their particular RFID tag that has been assigned for that particular vehicle in which RFID Reader reads and verifies the vehicle information and then deducts the tax amount from their prepaid account balance. If any of the processes fails that vehicle is trapped and now that particular vehicle is being verified manually and then passed through the manual toll gate. This system helps in saving time, money and fuel conservation as well as helps in trapping the unauthorized illegal vehicles.
