RFID is essentially a means of item identification. It is believed that it will eventually replace the traditional bar code that is widely used today and become the most effective way of item identification. Walmart and RFID technology
Among the 50 most influential Internet figures named by "Network World" in 2003, Wal-mart's CIO (Chief Information Officer) Linda Dillman is second only to Cisco (Cisco) President and CEO, Microsoft (Microsoft) Chairman and Chief Software Architect, IBM Chairman and CEO, Hewlett-Packard (HP) Chairman and CEO and ranked fifth.
This ranking is based on multiple judgments, including the person’s title and responsibilities within the company, the person’s insight (determined by the accuracy of the person’s predictions in the media and public speeches last year), and the person as a role model How it affects the network industry and personality characteristics. So how did the chief information officer of the retail industry become one of the most influential online tasks?
This is because a decision made by Linda Dillman in June 2003 may have a profound impact on the company's internal and even part of the network field and the entire network industry, as well as the entire business world, or even national government departments. While Dillman is serving the direction of Wal-Mart's technological development, it is not only for this huge and friendless retailer, but also for thousands of suppliers-the ripple effect it produces will affect the entire online industry.
At a retail trade show in June 2003, Dillman told the exhibitors that Wal-Mart would require its top suppliers to implant radio frequency identification (RFID) chips on their items in 2004, and by 2006 All other suppliers must do the same. Analysts believe that this alone may create a $2 billion RFID market.
The birth of RFID
So what is RFID? When was it produced?
The RFID that everyone pays attention to is actually nothing new. The history of RFID can be traced back to the Second World War (around 1940). The main function of RFID at that time was to distinguish between enemy and British aircraft. . At that time, the principle applied was to install a similar active tag (Active Tag) used today on a British aircraft, and transmit a signal to the tag on the aircraft through radar. At this time, the tag will send an appropriate response signal. , You can tell that the aircraft is your own. This system is called IFF (Identity: Friend or Foe). The current flight control in the world is still based on this.
The Chinese name of RFID is radio frequency identification, which is the abbreviation of "Radio Frequency Identification" in English, and is a kind of non-contact automatic identification technology. The simplest RFID system consists of three parts: a tag, a reader, and an antenna—in actual applications, it also needs the support of other hardware and software. Its working principle is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag), or actively Send a signal of a certain frequency (Active Tag, active tag or active tag); after the reader reads and decodes the information, it is sent to the central information system for relevant data processing.
IDC predicts that the cost of RFID software, hardware and services in the US retail supply chain will increase from US$8.5 million in 2002 to nearly US$1.3 billion in 2008. Forrester Research said that RFID will be one of the four major IT trends in 2004, and the "Internet of Things" built by it will bring revolutionary changes to the world. It is precisely because of the huge market potential of RFID that IT giants such as IBM, SAP, and Microsoft have already invested heavily in the development of this technology and solutions, trying to get a share of it.
