At present, the computer industry is a trend toward development: To meet the business needs, as close as possible to provide anytime, anywhere real-time picture of the information. However, to achieve this goal, limited by the timeliness of the original data. RFID is an automatic identification without human intervention and technology assets, which makes computer systems can not only identify the object, and can understand the state of these objects. Such as the use of RFID technology, smart cards, in the early application of some controversy, but its value clearly shows that, RFID network identity as an important part will be booming.
In many applications, black ps sheet RFID technology is only a logical extension of bar code technology, eliminating the need for active scanning of goods, in the basic supply chain to improve productivity. MIT's first Auto ID significantly reduces RFID "tag" the cost of printing bar codes on price tags with a very competitive general electronic product code (Electronic Product Code, EPC) and the Universal Product Code (Universal Electronic Product Code , UPC) bar code system, RFID products will gradually become the standard label. Recently, the U.S. retailer Wal-Mart's decision to require its suppliers to use RFID within a year the product label tray.
Currently, ps sheet for carrier tape RFID has had many unsuccessful EPC version, however, we still see rapid deployment of this technology. Procter & Gamble brand manager Kevin Ashton, former mentioned it when the excitement comes from the Center for Automatic Identification strong force of infection. He said, "This is bigger than the Internet for the company to use sensors to create a method of identifying goods around the world, is a big problem, which will completely change our past, from manufacturers to customers, or even by recycling products the product's inherent tracking mode. In fact, we have created things. "
Future Engineering Research Institute director Paul Saffo said RFID, said: "Once all of these machines can communicate with each other, they will make the business even to the whole world can not match the speed of human progress faster and more efficient."
All ships on the ocean
RFID is not just the "next generation bar code" technology. It provides a direct connection to the computer interface to the physical project. Over the past decade, the military built the world's large network of JTAV RFID network. The network uses active RFID tags and GPS global positioning system tracking of military supplies, significant improvement in military logistics. A report on the 1991 first Gulf War the U.S. military supply problems encountered in analysis of the implementation of this system to become the driving factors. In this war, the U.S. lost a lot of logistical supply shipments, resulting in extra transport and waste of resources. Even if the military supplies reached the right place, had to open 75% of the containers to see which stored items. In recent military conflicts, JTAV fully reflect the value of the U.S. military supplies transported greatly reduced, while the munitions and ammunition missing or incorrect allocation of the situation is significantly reduced.
According to the U.S. Department of Defense and created JTAV networks play a key role in the organization of Savi Technology's report, the geographical scope, JTAV is the world's largest RFID network. It can be 400 in 40 countries read the RFID information sites, including ports, military bases, railroad terminals and around the world. JTAV can track the 270,000 cargo containers, or even real-time location via satellite where the container ships. RFID tags per hour, reported their information, at the same time, JTAV also follow them.
JTAV successful generals in the Army Materiel Command PaulJ.Kern reflected in a statement: "No other system can provide such a necessary level of detail visible. RFID is the joint warfighter Marine Command (TheCoalitionForcesLandComponentCommand, CFLCC) to identify key cargo, the cargo to locate, and predict the arrival of the only tools.
