RFID is used for reading the physical tags on single products, cases, pallets, or re-usable containers which emit radio signals to be picked up by reader devices. The complete RFID picture combines the technology of the tags and readers with access to global standardized databases. This paper is to make the payment automation in toll gate using RFID technology. Here, the process is worked out by using Arm7 based LPC2129 microcontroller along with GSM modem. Whenever, the vehicle enters the toll gate, the vehicle is detected automatically through the RFID card present with owner.
