Path Loss Optimization in RFID based Passport Identification at Airport Logistics System

Abstract

Radio Frequency Identification (RFID) is a contact less technology that has multiple application in the modern era. RFID is used in passport identification at airport to match and identify the multi user .A Multiple Input Multiple Output (MIMO) is used in RFID to identify the multi user simultaneously. The information is transmitted from multiple transmitter and receiver of RFID system simultaneously so there is a change of interference also if the RFID system is used in different environmental or in different height then there is chance of path loss during the signal transmission from the transmitter to receiver .Successive interference technology and optimal value of frequency with distance is maintained to minimize path loss.
