ERP SYSTEM-An RFID BASED TOLL TAX
Project Platform : EMBEDDED C 89X51 MICROCONTROLLER
Languages Used : EMBEDDDED C
Project Cost : 12000
Description
RFID Toll Road Payment systems have really helped a lot in reducing the heavy congestion caused in the metropolitan cities of today. It is one of the easiest methods used to organize the heavy flow of traffic. When the car moves through the toll gate on any road, it is indicated on the RFID reader that it has crossed the clearing. The need for manual toll based systems is completely reduced in this methods and the tolling system works through RFID. The system thus installed is quite expedient reducing the time and cost of travelers since the tag can be deciphered from a distance.
The people traveling through this transport medium do not need anything else to get on a highway, instead the RFID tag carried by their vehicle does every thing. A commuter traveling through this medium gets to know how much amount has been paid and how much money is left in the tag. It does not require the person to carry cash with him to pay the toll tax all the time. The long queue waiting for their turn is reduced, which in-turn reduces the consumption of fuel. The RFID toll payment systems are really used in preventing trespassing on borders. The software solution developed can ensure a smooth running of vehicles without any need for further development. The software controlling these RFID tags and readers is easy to implement.
Here Basic idea is to develop the automatic challan system that can check for signal break by any vehicle. The RFID Reader reads the information like vehicles no. and automatically send a report to the owner of vehicles and simultaneously an information is given on the site itself through LCD.
INTRODUCTION TO RFID
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. The technology requires some extent of cooperation of an RFID reader and an RFID tag.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

Typical Applications for RFID
• Automatic Vehicle identification
• Inventory Management
• Work-in-Process
• Container/ Yard Management
• Document/ Jewellery tracking
• Patient Monitoring
The Advantages of RFID Over Bar Coding
1. No "line of sight" requirements: Bar code reads can sometimes be limited or problematic due to the need to have a direct "line of sight" between a scanner and a bar code. RFID tags can be read through materials without line of sight.
2. More automated reading: RFID tags can be read automatically when a tagged product comes past or near a reader, reducing the labor required to scan product and allowing more proactive, real-time tracking.
3. Improved read rates: RFID tags ultimately offer the promise of higher read rates than bar codes, especially in high-speed operations such as carton sortation.
4. Greater data capacity: RFID tags can be easily encoded with item details such as lot and batch, weight, etc.
5. "Write" capabilities: Because RFID tags can be rewritten with new data as supply chain activities are completed, tagged products carry updated information as they move throughout the supply chain.
