2、istic providers practicing this new technology to their products and services. Therefore, it brings both opportunities and challenges to RFID researchers. This article briefly introduced component, principle and characteristic of the RFID technology. In this paper we compared RFID and the traditiona
3、l bar code, and then provide a brief survey on RFID applications .Keywords: RFID Application Logistic IntroductionRadio frequency identification (RFID) is a new identification technology. RFID has a greater number of benefits than its predecessor, the bar code. It is not universally adopted in many
4、industries due to its high cost hitherto. However, RFID is unmatched advanced because it does not require sight scanning, it acts to reduce labor levels, enhances visibility, and improves inventory management.The popularization of RFID (Radio Frequency Identification) provides a solution of the loca

RFID location and tracing system, measures the space location of object based on unique identification tag and signal intensity of RF communication between reader and tag in object, mainly apply to indoor location, which GPS system is not suitable for . RFID, a non

RFID tag, a special microchip, implanted in commodity, can trace and manage physical object, is an important means of logistics management informatization and tracing informati

As figure 1, RFID work principle. Figure 1-1,RFID work principleCurrent Research Focuses of RFIDWith the growing
8、 maturity of RFID technology and the drop in price of RFID tags, RFID attracts increasing interests from both industry and academic. By attaching RFID tags on objects, one could keep track on and manage those objects. This technology gradually replaces current widely adopted barcode systems2. 1.RFID
9、 Tag and Bar codeBar code is widely adopted for goods and object identification. One could find bar code on every packaged item in supermarkets. Zebra Company is one of the leading bar code providers and provides on-demand specialty digital printing and automatic identification solutions in more tha
10、n 100 countries around the world. About twenty years ago, the company mainly produced the standard labels. Now Zebra also moves to RFID business. From the application point of view, bar code and RFID share a similar market, especially in retail aspect. Will RFID replace bar code?From conceptual poin
11、t of view, RFID tag and bar code are also similar. Both of them target to facilitate goods management by providing an easy to fetch identification code. There are two major differences between them，barcode is read-only and must be in line-of-sight from the reader .Comparing with bar code. RFID is ab
12、le to transmit data by radio frequency and alter data stored on the RFID tag chip. This long range and non-contact operation allows automation to reduce man power requirement. The most important advancement of RFID over barcode is that it allows identification of individual item from a group of same
13、 type products. RFID also provides real-time traceability environment for individual item through all process in the supply chainOwing to these features, RFID reduces the cost for warehouse, distribution and inventory. This directly brings more profit to companies and improves customer service remar
14、kably 2.2. Development of RFID StandardEnterprises gradually realize the great business opportunities created by RFID products and services. Major developments of RFID technologies are located at USA, Japan, Korea and China. For examples, Wal-Mart, the international department of the United States,
15、the United States Food and Drug Administration have promoted the development of RFID.A successful example is Wal-Mart. They replaced some barcodes by RFID products which saved US$6.7 billion barcode cost,US$0.6 billion storage cost and US$0.57 billion missing and theft cost. However, RFID does not have a single global standard yetUSA is developing its RFID standard for both hardware and application areas. The RFID standard of European mainly follows the US
