Abstract:
An embedded system is a special-purpose computer system designed to perform a dedicated function. Embedded system is fast growing technology in various fields like industrial automation, home appliances, automobiles, aeronautics etc. Now more than ever, embedded systems designers are recognizing the value of wireless. From home light switches and entertainment systems to industrial controls to remote monitoring and communications, wireless is permeating an increasing variety of applications that might once have been thought of as either standalone or otherwise happily tethered to a wire of some sort.
RFID is the special type wireless card which has inbuilt the embedded chip along with loop antenna. The inbuilt embedded chip represents the 12 digit card number. RFID reader is the circuit which generates 125KHZ magnetic signal. This magnetic signal is transmitted by the loop antenna connected along with this circuit which is used to read the RFID card number.
This paper focuses on an electronic toll collection (ETC) system using radio frequency identification (RFID) technology. Research on ETC has been around since 1992, during which RFID tags began to be widely used in vehicles to automate toll processes [1]. The proposed RFID system uses tags that are mounted on the windshields of vehicles, through which information embedded on the tags are read by RFID readers, The proposed system eliminates the need for motorists and toll authorities to manually perform ticket payments and toll fee collections, respectively. Data information are also easily exchanged between the motorists and and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human errors.
