We are offering a rfid smart card is any pocket-sized card with embedded integrated circuits that can process and store data and communicate with a terminal via radio waves. There are two broad categories of contactless smart cards. Memory cards contain non-volatile memory storage components and perhaps some specific security logic. Contactless smart cards do not contain and ordinary read-only rfid but they do contain a re-writable smart card microchip that can be transcribed via radio waves.

We are one of the largest Manufacturers and Suppliers of RFID Based Toll Plaza System in India. Our electronic/automated toll collection systems are very popular these days. They do not require manual collection and operation of toll barriers. The details about the vehicles and payment are stored in an RFID based system. In a toll plaza system interfaced with RFID, each user holds a unique ID for his vehicle. When the user scans his tag while passing through the plaza, a certain amount is deducted from his account. A user may also recharge his account in case of insufficient balance. The toll amount is charged based on the category of the vehicle driving through the plaza. The vehicle categories taken here are two-wheeler & four-wheeler.  The project has been developed by interfacing RFID with AT89C51. The relevant messages are also displayed on a 16x2 LCD.   Description :Low frequency RFID work at 125 KHz frequency with radio waves. There is a coil inside the RFID tag and when it is influenced by a magnetic field, it sends a 12 byte identity code to RFID reader for further processing. The RFID tag is used as a unique identity for account of a particular user. When a vehicle drives through the toll plaza, its driver is prompted to scan his RFID tag. If the identity (serial number of the tag, i.e., 12 byte data) is matched with the one already stored in the system, the toll amount is deducted from his account. After this, the vehicle gets immediate access to drive through.  When a new user registers his vehicle, he is prompted to specify the vehicle type. LCD displays a message asking the user to ‘press 1 if 2 wheeler; press 2 if 4 wheeler’. After pressing one of these keypad switches, the vehicle is registered on the system. This RFID based toll system also has some additional features. A new user can register him with the system. Also an old user can recharge his account balance. The amount for recharge can be entered in the system through a numeric keypad interfaced with AT89C51.  Two-wheeler and four-wheeler categories have different charges. In this case the toll amount considered is Rs.10 & Rs.20, respectively. After registration, the user is prompted to scan his tag or ID. The serial code of the tag is identified by the reader module and is sent to AT89C51 for comparison with stored data. If the ID is matched by the microcontroller, the toll amount (depending on vehicle type) is deducted from user’s balance and user gets to drive through the plaza. If the tag is not recognized by the system, a message (‘Wrong ID’) is displayed on LCD screen. A new user needs to press the ‘*’ switch to register himself after which his identity is verified with RFID tag. The new record is then stored by the microcontroller to grant future access. The system also shows ‘Error’ if the tags do not match during verification. If balance in user’s account becomes less than Rs.30, a warning message ‘Low balance’ is displayed on LCD. In this case the user still gets the access through the system. The system also prompts the driver to recharge the account. If balance reaches below Rs.10, ‘Insufficient balance’ is indicated on LCD screen. The user does not get access until he adds more balance to his account. The recharge amount is entered by using a keypad. Back space can be used while entering the amount by pressing ‘*’ button on keypad. It also has a safety feature that if different tags are scanned through the reader at the time of registration, LCD displays ‘you have shown different ID’. When an RFID tag comes in this range, the reader detects it and sends a unique code of the tag serially. This serial code, consisting of 12 bytes, is received by the microcontroller. This code is the ID for the user and is stored as an array in the microcontroller. If the ID is matched with this code stored in array of microcontroller, the user is granted access though the toll plaza.
