Using RFID to track the Bus system
Transport systems in many cities track their buses using Global Positioning Systems (GPS). Now this is an expensive piece of technology. In the United States these systems can cost the at least $10,000 per bus.
However, no need to worry. A couple of students have devised a new tracking system based on RFID that will cost $2,000 to $4,000 per bus. They have devised simple solution. For a bus system, each bus is outfitted with a reader. First, they tagged each bus stop. When the bus arrives at a bus stop, the bus' reader reads the tag's unique code and transmits the information to a database through a wireless or cellular network.
After that, software converts that database into a Web site. Users can go to the web site that has bus-route maps telling users about a bus' last-known stop and the time when it was there.
