Brief introduction of RFID
Today I'll talk about RFID technology, when we first get in touch with
may feel confused, but actually, it penetrates in every corner in our life. When
we go to the dinning
hall in school, we may use

is a typical
usage of RFID technology.
At this moment, you must be very curio
whether the RFID
technology was developed in recent years? Actually, RFID technology can
cked back to
the World War II
. At that time
this technology was
mainly used in
and hadn’t got
promotion in civilian field.
Along with the enhancement and popularization of chip and electronic
technology, Europe starts to apply the RFID t
echnology to the road
To the beginning
21st century, RFID
has welcomed a brand

various countries' attention in civilian field's value, especially in the
Western developed c
Here’s another example that uses RFID technology. Do you still remember
the EXPO hold in Shanghai?
The EXPO future store score a success by using a
commercial mode based in RFID technology
. Each of the guests will get a IC
Card and a palm compute
r, if they are interested in something, they can scan it
by using the palm computer, and the price will display on the screen. If they
want to buy it, they can order it. When they check out, they don’t need to wait
in line, just swipe the IC Card and they
will know which bill you should pay. As
you see, the RFID technology penetrates the whole process.
After the above introduction, you should have already known that the
RFID technology is of great help
our life and work. Now, let me
introduce briefly wha
t on earth the RFID is.
RFID's full title is Radio Frequency Identification; it is one kind of

I hope you have found
useful, thanks for your listenin
After listening Professor Li’s short but excellent introduction about
RFID, I believe that everyone has certain understand about the concept,
function and development of RFID. Is there any questions? Well, for there
no question. Now let’s welco
me Dr Qi.
Thank you! Excellent presentation…OK, profess Qi has just given us
a lot of dates and details about the RFID system ’s composition and
classification. Is there any question about Dr.Qi’s talk?
Ok, thank you Dr. Qi. Let’s move on to the next speak
Dr Ma has showed us the applications of RFID. Through her
presentation, we know RFID technology has been applied in many fields, and
is the most advanced automatic identification technology. RFID has
penetrated in every corner in our life and su
pplied us a huge of convenience.
Any questions ? Ok, let’s welcome the last speaker Professor Xu.
Thanks for Professor Xu’s perfect presentation. From
introduction of the current situation of RFID, we can see that there are many
problems to be solved
. But its future prospect of development is beyond
Now it is time for you to ask questions, is there any questions
Thanks Dr Xu, and thank all the members and audiences, our presentation is
over! Let us invite professor
give us a conclusion of this seminar.

I will introduce
the RFID system
A conventional RFID system is made up of five components: electronic tag,
reader, antenna, middleware and application software.
tags and readers.
An RFID tag is comprised of a microchip containing identifying information
and an antenna that transmits this data wirelessly to a reader.
These are different kinds of readers.
RFID reader sends radio waves
between one centi
meter and 30 meters or more. If a tag enters this
electromagnetic region, it detects the activating signal from the reader. The
RFID reader decodes the data stored in the integrated circuit of the tag, and
communicates them to a host system.
An RFID anten
na consists of a coil with one or more windings and a
matching network. It radiates the electromagnetic waves generated by the
reader, and receives the RF signals from the tag.
Middleware refers to specialty software that sits between the reader
nd the true application software to help process the significant
amount of data coming from the tags and readers.
To drive value from RFID, you must deploy RFID
enabled software that

I will introduce
the classification of RFID.
According to the application of frequency, RFID can be divided into
frequency, ultra high
frequency and microwave.
According to the energy supply mode, RFID
can be divided into pass
active RFID. Passive tags have no battery and "broadcast" their
data only when energized by a reader. Active tags are capable of broadcasting
their data using their own battery power.
The extra capability and read ranges
of active ta

hey are several times mo
expensive than passive tags.

RFID current situation
The RFID market is congested, with a massive amount of diverse players
Chip markets, transponder manufacturers, system integrators or
consultancies, all of
whom offer different, and generally proprietary,
products and services. Available systems consist of different frequency
ranges, transfer modes. For a potential customer, it is difficult to
acknowledge the distinct benefits and disadvantages of these diff
Currently RFID technologies cannot offer a so
called “killer application”
which is an off the shelf standard solution. A selection of different RFID
systems has to be done by the users depending on the organizational
and technological requirements.
Due to the fragmented market, the total cost of RFID implementation is not
transparent. Apart from the fact that transponder prices range from 50
eurocent to 80 eurocent, the exact price calculation as part of a cost
analysis has to take into consideration not only the investment in the
transponders and readers, but also other cost drivers, such as peripheral
systems, software and integration effort.
The discussion in the media regarding RFID implementations often is
by high promises in terms of expectations, that is cost reduction and
improved visibility of the supply chain. If these expectations are not fulfilled
at short notice , potential customers tend to lose their interest in RFID.
RFID technologies requi
re a huge effort in terms of standardization. RFID
standards are a major issue in securing the high investments in RFID
technology on different levels(e.g. interface protocol, data structure). Not
only different standards co
exist in parallel, but also dif
ferent actors with
sometimes divergent interests influence the standardization life cycle.
Ok, it is my pleasure to be here for summary. First, thanks for the four
