RFID USED IN EMIRATES
Feb 19, 2008—Emirates Airline has
begun a six-month technology trial to test the use of RFID to improve the
tracking of checked luggage. Instead of using the standard, bar-coded ID tags
that airlines normally employ to identify baggage, Emirates is placing tags
with embedded UHF EPC Gen 2 inlays onto each checked bag on five daily flights
between London's Heathrow Airport and Dubai International Airport. Bags checked
onto a daily Emirates flight to and from Hong Kong International Airport will
also be tagged.
The airline hopes using RFID
combined with automated bag sortation equipment will increase the amount of
luggage it can accurately identify and sort, thereby decreasing the number of
bags that fail to reach their destination on time. Emirates is also using a
secure database to enable personnel at each airport to follow the tagged bags'
movements from the point of intake to the time they are loaded onto a plane.
The airline is investing more than a half million dollars in the six-month
project and expects to place RFID-enabled tags on approximately half a million
bags.
To track the bags from the point
of departure to the point of arrival, RFID interrogators read the unique ID
from the inlays in each luggage tag—which are otherwise identical to conventional
tags and include a bar code—as the bags are moved through a number of
chokepoints within each airport. Conventionally, bar-code scanners are employed
to identify the tags, but because bar-code technology requires a clear line of
sight between the scanner and a printed bar code, the read is often missed due
to the orientation of the label to the scanner. The typical successful read
rate of baggage bar codes is roughly 85 percent, says Pankaj Shukla, director
of RFID business development for Motorola, whose RFID interrogators are being
used in Heathrow Airport as part of the pilot program.
Past trials of RFID technology in
baggage handling applications, Shukla says, show the percentage of successful
read rates to range from the low 90s up to 99. Bags that aren't automatically
identified through their bar code or RFID number are diverted and manually
handled, thus increasing the likelihood that a bag will be delayed and not
loaded onto the same flight as its owner. According to the International Air Transport
Association (IATA), a trade group composed of airlines around the globe, the
annual cost of mishandled baggage to the industry is more than $3 billion.
An IATA report published in 2007,
however, maintains that RFID will not completely eliminate late luggage and its
associated costs. According to the report, problems in reading the bar-code
tags on luggage are responsible for only 9.7 percent of all mishandled luggage
across the industry. "There are many reasons for the mishandling of
baggage," the report indicates, "and not all of these may be
addressed with RFID."
