Brief introduction of RFID

Today I'll talk about RFID technology, when we first get in touch with
it
, we
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
all
-
purpose Card

instead of
buying meal ticket
. It’s very convenient
. In fact,

all
-
purpose Card

is a typical
usage of RFID technology.

At this moment, you must be very curio
us,
whether the RFID
technology was developed in recent years? Actually, RFID technology can
be tra
cked back to
the World War II
. At that time

this technology was
mainly used in
Military field

and hadn’t got

any
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
charge and
other

civilian field
s.

To the beginning

of
21st century, RFID
has welcomed a brand
-
new period of development, it starts to obtain
various countries' attention in civilian field's value, especially in the
Western developed c
ountr
ies.

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
to

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
non
-
contact automatic identification technology. It can identify target
automatically and obtain related data through the radio
-
frequency signal.
And t
he recogni
tion work does not need the manual intervention. The
RFID technology may distinguish high
-
speed
motion objects

and
can

distinguish many labels

at one time.

T
he operation is quick

and

convenient.


I hope you have found
these

useful, thanks for your listenin
g.

RFID

System

Composition and Classification

Good
morning
, everyone

I’m very glad to be here to

introduce my study
and communicate with you all on RF
ID .
Firstly,
I will introduce
the RFID system
composition
.

A conventional RFID system is made up of five components: electronic tag,
reader, antenna, middleware and application software.

Now
,

let’s look

at some

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.

A
n
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
network a
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
processe
s

RFID data and passes RFID data on to other systems as required
.

Then,

I will introduce
the classification of RFID.

According to the application of frequency, RFID can be divided into
low
-
frequency, high
-
frequency, ultra high
-
frequency and microwave.

According to the energy supply mode, RFID
can be divided into pass
ive,
active

and semi
-
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
gs
, however, come with a cost
. T
hey are several times mo
re
expensive than passive tags.

The above content

is what I want to say. Thank
you!

RFID current situation

1.

The RFID market is congested, with a massive amount of diverse players
such as

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
erent RFID
solutions.

2.

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
specific process
and technological requirements.

3.

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
-
benefit

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.

4.

The discussion in the media regarding RFID implementations often is
driven
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.

5.

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.

Summary

Ok, it is my pleasure to be here for summary. First, thanks for the four
presenters’. They give us very fine performances. Next, it is time for m
e to make
one last appeal.

The first talks about the development history and definition. With the
development of chip and ele
ctronic technology, RFID applie
s

worldwide. RFID is
short of Radio Frequency Identification Device. It can recognize target
automat
ically and acquire relevant data. The advantage of RFID is fast and
convenient.

Later on, the next speaker presents RFID system composition and
classification. A traditional RFID system contains five parts: electronic tag

antenna

reader

middleware and application software. RFID is sorted by two
standards.

The following presenter discusses the application of RFID. She presents six
main application: portal application

conveyor/assembly Line

hand held
application categories

i
ntelligent labels

products tracking

demo
-
smart
cabinet

additionally some smarter applications.

The last relates the current situation. The situation chiefly includes four
aspects. RFID market is retardant. It hasn’t been the next “killer application”.
The
general cost is obscure. The media about RFID depends on expectation.

Finally, I want to talk about the future of RFID.

With the RFID technology in logistics, manufacturing, public information
service industries such as the extensive application of innovat
ive cost savings
arising from improvements and efficiency, in order to promote the construction
of social information provides
an important opportunity. Against this backdrop,
RFID technology and the telecommunications industry is increasingly given rise
to attention. This new wireless technology based on business models and
business forms appear, is bound to change the traditiona
l telecom industry
development.

Present ,because the China's RFID technology is not mature, some related

standard is still uncertain, reliable and simple technology application will be
more feasible. But, in the near future, with the cost of RFID equipment

dorpping,
the lower standard unifying, gradually digital information technology in
industries extensive
ly

applying, RFID technology will have a broad prospect,

and its potential value will be gradually plays out. In the future society, RFID will
everywher
e.

At last, thanks for your attention!
