【正文】 opment 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 research and development on automation and home appliances’ intelligent. The China government also realizes the industrial value of RFID and is formulating its own RFID is considered as the “world factory” because of its large scale and wide range of industry. Therefore, China has the potential to develop its own standard. In parison to aforementioned countries, although China is late in starting its RFID industry, it grows up rapidly and is gradually being very petitive in worldwide. Several panies,. Invengo,in China are making progress on the development of their own brands of RFID products． RFID Technology Development Hardware ponents are mon to all RFID applications while different software leads to different RFID application, Major issues in RFID hardware include product miniaturization,cost reduction, large production,etc． Some panies,such as German Siemens, speeded up the development of RFID chips to enrich their products and to meet users’ integration density of current UHF RFID chips has been greatly increased. The new Generation 2() RFID tags quickly replace old generation tags and have a dominant share on the RFID application market. Fujitsu developed the first RFID tag with 64 KB memory which has been successfully adopted in aviation industry owing to its high access speed and large price of RFID readers are monotonically decreasing while the capacities of RFID readers are enhancing, in recent year, Microsoft issued the BizTalk Server which integrates the RFID with Microsoft product application. As RFID systems being an important part of everyday life, sensitive and private information may be stored in RFID tag. This security threat bees more serious and puts a severe limitation to the promotion and deployment of RFID , owing to the limitation of space and cost of a RFID tag, RFID tag usually does not equip with high power security tags are frangible to attack .Without appropriate security , anyone could read， alter and delete data on the RFID tags with a RFID reader/, RFID tags are easy to clone. This is a big threat to access control ,a number of security measures are available for ISO standard 15693 for data authentication is adopted in bank card authorizations and building access control ,all security measures have some shorting and it has bee a hot research topic in RFID． RFID Applications RFID applications focus on logistic,toll system,ticket, healthcare,security and identification systems. Logistic One of the most famous RFID applications is supply chain management. RFID tags are attached to goods. Items or parts in the supply chain and all items are tracked by RFID readers from manufacture to point of sales. Megatrux ,a top l00 logistics pany in the world, has applied Motorola RFID plan to its supply chain management. Their customer services have been improved while the costs have been reduced greatly． RFID also has a great value in product delivery. We could track the handing process and current location of the product from pick up to delivery with RFID tag attached on it. It helps to relieve incorrect delivery owing to human mistakes. It does not require one to one line of sight reading which is required for barcode. This reduce the ti
