【文章內(nèi)容簡介】 manage physical object, is an important means of logistics management informatization and tracing informatization . The ponent of RFID system including: (1) Tag (transponder): implanted in object to be identified. (2) Reader: can read or write/read, according to the structure and technology. As figure 1, RFID work principle. Figure 11,RFID work principle Communicate with puter Readere Electromagic wave (operation instruction and new data) Tag Emit ID code and data 12 2. Current Research Focuses of RFID With the growing maturity of RFID technology and the drop in price of RFID tags,RFID attracts increasing interests from both industry and attaching RFID tags on objects,one could keep track on and manage those technology gradually replaces current widely adopted barcode systems． 2. Tag and Bar code Bar code is widely adopted for goods and object could find bar code on every packaged item in supermarkets. Zebra Company is one of the leading bar code providers and provides ondemand specialty digital printing and automatic identification solutions in more than 100 countries around the twenty years ago, the pany mainly produced the standard labels. Now Zebra also moves to RFID the application point of view, bar code and RFID share a similar market, especially in retail aspect. Will RFID replace bar code? From conceptual point of view, RFID tag and bar code are also of them target to facilitate goods management by providing an easy to fetch identification are two major differences between them， barcode is readonly and must be in lineofsight from the reader .Comparing with bar is able to transmit data by radio frequency and alter data stored on the RFID tag long range and noncontact operation allows automation to reduce man power most important advancement of RFID over barcode is that it allows identification of individual item from a group of same type also provides realtime traceability environment for individual item through all process in the supply chain． Owing to these features, RFID reduces the cost for warehouse, distribution and directly brings more profit to panies and improves customer service remarkably． 13 . Development of RFID Standard Enterprises gradually realize the great business opportunities created by RFID products and developments of RFID technologies are located at USA,Japan,Korea and examples, WalMart,the international department of the United States,the United States Food and Drug Administration have promoted the development of successful example is replaced some barcodes by RFID products which saved US$ billion barcode cost,US$ billion storage cost and US$ billion missing and theft , RFID does not have a single global standard yet． USA is developing its RFID standard for both hardware and application RFID standard of European mainly follows the USA standard. Japan has strong research and product lines on intelligent munication and home proposed the UID standard which is adopted in Japan homeland Ministry of Economy ,Trade and Industry(METI) is pushing for the development and applications of RFID in two major missions of METI are to reduce the cost of RFID tags and to promote the Japanese standard to focuses their RFID r
