Critical Thinking

The E-field levels recorded for the whole system

The development of global associations and dual transfer
flights increases the passenger and baggage volumes
creating big challenges to airports and airlines. Existing
baggage handling system relies on an aging Barcode
system with high error percentage.
In this system, transport operation is conducted at very
low speed and precision. For reading and control of
barcodes, barcode readers need to carefully read barcodes
in direct sun light. Current bag tags include a bar code.
These bag tags are printed using thermal or barcode
printers that print on an adhesive paper stock. This printed
strip is then attached to the luggage at check in. This
allows for automated sorting of the bags to reduce the
number of misrouted, misplaced or delayed bags. The
limitations of this technology were apparent when a fully
automated cart-based system significantly delayed the
airport’s opening. While the inability to reliably read all
barcode tags in the installation was a part of the problem,
it was one of several technical reasons for the delayed
opening. Nevertheless, automated sorting of baggage
using laser scanner arrays, known as automatic tag
readers, to read bar-coded bag tags is standard at major
airports. Bar codes cannot be automatically scanned
without direct sight and undamaged print. Forced by
reading problems with poorly-printed, obscured,
crumpled, scored or otherwise damaged bar codes, radiofrequency
identification (RFID) chips embedded in the
tags can be very useful.
Thus airline requires a highly efficient method to handle
the increasing passenger and baggage volumes and thus
the trending RFID technology has drawn the attention of
the airline. Barcode reading problems cause 9.7% of all
mishandled baggage and failures to receive a baggage
status message contribute to a further 11% of mishandled
baggage.Sample et al. focused on the use of RFID
technology in the US department of Transportation’s
(DOT) international airport security initiative in Nigeria.
One of the uses of RFID baggage tags, in conjunction
with RF handheld readers and boarding pass readers, is to
verify passenger boarding versus luggage loading for
positive passenger baggage matching on flights departing
for the U.S. and other international locations.Wong et al.
discussed workers’ safety concern due to radiation
emissions from a recently installed 900 MHz RFID
baggage handling system at Hong Kong International
Airport. They concluded that the operation of the RFID
system is considered a safe system, as the E-field levels
recorded for the whole system is well below the ICNIRP
(International Commission on Non-Ionizing Radiation
Protection) restricted level.
III. SCOPE PROJECT
This project involves with study the RFID based airport
luggage security system. RFID is a fast and reliable
means of identifying just about any material object.
Primarily, the two main components involved in RFID
system are the RFID tags and RFID reader. RFID tags
that used in this project is passive type with frequency of
13.56Mhz.The maximum read distance about 1.5meters
but with a constraints of budget, RFID 125 kHz tag and
reader are used and it is affordable for this project. This
project will focus on RFID interface and RFID hardware.
RFID interface will be programmed by using visual basic
programming to trace the passenger and luggage is
authorized or unauthorized. This system will use MSSQL
as a database to insert all the details of passenger and their
luggage. RFID will interact with the database and come
out with the output either the passenger and luggage is
authorized or unauthorized.
