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 curious, whether the RFID technology was developed in recent years? Actually, RFID technology can be tracked 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 technology to the road charge and other civilian fields. 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 countries.
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 computer, 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 what 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 the recognition work does not need the manual intervention. The RFID technology may distinguish high-speed motion objects and can distinguish many labels at one time.The operation is quick and convenient.
I hope you have found these useful, thanks for your listening.

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 RFID .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 sometags 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.An RFID reader sends radio waves between one centimeter 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 antenna 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 and 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 processes 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 passive, 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 tags, however, come with a cost. They are several times more expensive than passive tags.
The above contentis what I want to say. Thank you!

Radio Frequency Identification (RFID)
——Applications
RFID applications
1、Portal Applications
We can get information as follows:
（1）、Bill of Lading Material Tracking
（2）、Limited number items at forklift speeds
（3）、Electronic receipt & dispatch
（4）、Wrong destination alert
（5）、Pallet/container item tracking
2、Conveyor / Assembly Line
With RFID installed in the Conveyor / Assembly Line, Reading / Writing Operations can realize automation.It has more Higher Accuracy than Bar Code.
3、Hand Held Application Categories
We put Hand Held Application into three categories:Batch 、Wireless and Fixed Station .
Now we give some Application Examples:
With a specificRFID device held in hand,we can read all the information we are interested.They can do Inventory Management and Material Handling.
4、Intelligent Labels
A smart label is usually consists of four parts,A paper label
with RFID inside、an antenna printed inside、a substrate and a chip
attached to it.With the label attached to a object,the object will have Identification function .
5、products Tracking
If a product is implanted RFID,we can track it through its entire lifetime.First,radio tag is placed on carton;then,the carton is sent to grocery store by dairy ships and it is purchased by consumer;Next,Consumer recycles milk carton.At last,carton arrives at recycling center.
6、Demo--Smart cabinet
At this part,we demo its work process through the smart cabinet.
Each cap of containers is affixed with passive read/write tag and reader antennas are placed under each shelf.If tagged item is removed from or placed in“Smart Cabinet”,“Smart Cabinet” periodically interrogates to assess inventory.Then,server/database is updated to reflect item's disposition and designated individuals are notified regarding items that need attention .
7、Some more smart applications
“Smart” appliances:Your closets can give you advice on style depending on clothes available and the ovens will know recipes to cook pre-packaged food.
“Smart” products:The clothing, appliances, CDs are tagged for store returns.
“Smart” paper:Airline tickets will indicate your location in the airport.
“Smart” currency:Money in your pockets can do Anti-counterfeiting and tracking.

RFID current situation
- 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 different RFID solutions.
- 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.
- 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.
- 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.
- RFID technologies require 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 different 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 me to make one last appeal.
The first talks about the development history and definition. With the development of chip and electronic technology, RFID applies worldwide. RFID is short of Radio Frequency Identification Device. It can recognize target automatically 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、intelligent 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 innovative 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 traditional telecom industry development.
Present ,because the China's RFID technology is not mature, some relatedstandard 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 extensively applying, RFID technology will have a broad prospect,and its potential value will be gradually plays out. In the future society, RFID will everywhere.
At last, thanks for your attention!
