Identification is pervasive nowadays in daily life due to many complicated activities such as
bank and library card reading, asset tracking, toll collecting, restricted access to sensitive data
and procedures and target Identification. This kind of task can be realized by passwords, bio-
metric data such as fingerprints, barcode, optical character recognition, smart cards and radar.
RadiofrequencyIdentification(RFID)isatechniquetoidentifyobjectsbyusingradiosystems.
It is a contactless, usually short distance, wireless data transmission and reception technique
for Identification of objects. An RFID system consists of two components: the tag (also called
transponder) and the reader (also called interrogator).
With all the recent hype over radio frequency Identification (RFID) and
the requirements to implement it, you might think that RFID can turn
water into wine, transform lead into gold, and cure the world’s diseases. You
might also be worried that RFID will enable Big Brother to track your move-
ments to within a foot of your location from a satellite five hundred miles up
in space. The truth is, RFID can do none of these things.
In this chapter, you find out the basics of what RFID is, what forces are dri-
ving RFID as a replacement for the bar code in the marketplace, and what
benefits RFID can offer
Radio frequency Identification (RFID) technology is witnessing a recent explosion of
development in both industry and academia. A number of applications include supply
chain management, electronic payments, RFID passports, environmental monitoring
and control, office access control, intelligent labels, target detection and tracking, port
management, food production control, animal Identification, and so on. RFID is also
an indispensable foundation to realize the pervasive computing paradigm—“Internet of
things.” It is strongly believed that many more scenarios will be identified when the
principles of RFID are thoroughly understood, cheap components available, and when
RFID security is guaranteed.
adio Frequency Identification (RFID) is a rapidly developing automatic wireless data-collection
technology with a long history.The first multi-bit functional passive RFID systems,with a range of
several meters, appeared in the early 1970s, and continued to evolve through the 1980s. Recently,
RFID has experienced a tremendous growth,due to developments in integrated circuits and radios,
and due to increased interest from the retail industrial and government.
RFID (radio-frequency Identification) is the use of a wireless non-contact system
that uses radio-frequencyelectromagnetic fields to transfer datafrom a tag attached
to an object, for the purposes of automatic Identification and tracking [38]. The
basic technologies for RFID have been around for a long time. Its root can be traced
back to an espionage device designed in 1945 by Leon Theremin of the Soviet
Union,whichretransmittedincidentradiowaves modulatedwith audioinformation.
After decades of development, RFID systems have gain more and more attention
from both the research community and the industry.
LIKE SO MANY OTHERS , THIS BOOK WAS WRITTEN BECAUSE WE COULDN ’ T FIND ONE LIKE IT . We
needed something to hand to all of those people who have come to us asking for “a good
book to read on RFID.” When we looked for candidates we found some great books, but
most were aimed at electrical engineers or top-level managers, with very little for those of
us who are in between. This book is for developers, system and software architects, and
project managers, as well as students and professionals in all of the industries impacted by
Radio Frequency Identification (RFID) who want to understand how this technology
works. As the title suggests, this book is about RFID in general and not just the most
recent developments; however, because so much is going on in the area of RFID for the
supply chain and especially the Electronic Product Code (EPC), we have devoted consider-
able space to these topics. Regardless of the type of RFID work you may be doing, we
think you will find something useful here.
Radio frequency Identification (RFID) is a type of automatic Identification systems
which has gained popularity in recent years for being fast and reliable in keeping
track of the individual objects. In RFID systems, contactless object Identification
is achieved using radio signals without the need for physical contact as the case
with other existing Identification technologies such as barcodes. Therefore, a huge
number of items can be identified in a short amount of time with high reliability
and low cost which makes the RFID technology very attractive for a wide range of
applications such as supply chain management, e-health, monitoring humans, pets,
animals, and many other objects, toll control, and electrical tagging. Furthermore,
RFID technology eliminates the human error and reduces the total cost of the
products.
Radio frequency Identification (RFID) is gaining in popularity, especially
as we find ourselves in this communications age and headed towards a
ubiquitous computing world. Automatic Identification systems become
an important aspect not just in today’s technology but also as part of our
daily life. We need RFID in our cars, transportation systems, access
points, and even simple transactions; we also acknowledge the need for
RFID in our logistics systems, healthcare, and tracking and locating
applications.
Radio frequency Identification (RFID) and Wireless sensor networks (WSN) are
the two key wireless technologies that have diversified applications in the present
and the upcoming systems in this area. RFID is a wireless automated recognition
technology which is primarily used to recognize objects or to follow their posi-
tion without providing any sign about the physical form of the substance. On the
other hand, WSN not only offers information about the state of the substance
and environment but also enables multi-hop wireless communications.
