Geographical information supply system and method using RFID, and traffic information supply system using RFID
First Claim
1. A geographical information supply system comprising:
- a reader which is positioned proximate to a road outputs a first signal and receives a second signal, wherein the second signal is generated in response to the first signal;
a tag which senses the first signal, converts destination information on a destination from said first signal into the second signal, and outputs the second signal;
a first control unit which extracts and outputs the destination information from the second signal, receives geographical information on the destination, and supplies the geographical information to a driver; and
a server which generates the geographical information corresponding to the destination information and outputs the geographical information to the first control unit.

Abstract
A system and method for providing geographical information to a driver of a vehicle using radio frequency identification (RFID). Also provided is a traffic information supply system using RFID. The geographical information supply system includes a reader provided near a road which outputs a first signal and receives a second signal generated in response to the first signal; a tag that senses the first signal, converts information on a destination into the second signal in response to the first signal, and outputs the second signal. Also included is a first control unit which extracts and outputs the destination information from the second signal, receives geographical information to the destination, and supplies the geographical information to a driver. A server generates the geographical information corresponding to the destination information and outputs the generated geographical information to the first control unit.
