RFID technology has been applied in the civilian field, which is mainly due to two driving forces: the first is that the cost of chip manufacturing has been greatly reduced, from the initial tens of dollars to a few cents, making RFID electronic tags accepted by managers; Second, users' widespread acceptance of RFID technology, the decision of Europe's largest supermarket Metro and the largest supermarket in the United States, Wal-Mart, to try RFID in early 2000 also accelerated the popularity of RFID technology. Similar to the situation in foreign countries, many users in China are desperately suppressing the desire for RFID. Instead, they are waiting for the development of RFID. “Is the technology more mature?†“Is there any cost reduction?†“Is there any other users already? Successfully applied?†This is the focus of their attention. "The biggest reason is that these customers simply use RFID as a simple alternative to bar code technology. This view limits their view of the rewards that RFID brings to them," said SteveWinter, president and chief operating officer of Intermec. Intermec is a global supplier of automatic identification and RFID equipment, and Steve has 30 years of experience in this field. He believes that "in fact, RFID should be seen as a new network technology." First of all, the bar code relies on passive manual reading. The staff needs handheld reading devices to scan one by one. The RFID reading device uses radio waves to automatically read a large number of tags in an instant. Secondly, the bar codes are fragile tags. Due to physical and chemical reasons, it is easy to fade and be torn. RFID is an electronic product that can be used in harsh environments. Third, barcode storage is small, and RFID tags are embedded with storage devices. Also, the problem with barcodes is that they are write-once and cannot be modified, and RFID can be written arbitrarily or modified. “This is a revolutionary breakthrough for ERP and SCM systems. In the past, material numbers could not track a single component. Today, the precise management of materials extends the reach of each component in every step. Whether it's quality control, automated management, or product lifecycle management, it's about the convenience that was unimaginable in the past," Steve said. He gave a very typical example. In warehouse management, the previous bar code technology, there are 24 boxes on the tray, the box has a bar code logo, use a barcode scanner to read 24 boxes, and then check the list. That is, whether the comparison of the loading list and the delivery list is consistent, if it is, it can be released, if not, it will prolong the storage time of the goods in the warehouse. A forklift equipped with an RFID reader can read the RFID tags on the 24 boxes in an instant, and can be transmitted back to the computer system for quick check through the network, if it is completely consistent with the list in the computer database. , you can release it. RFID can be said to have changed the original operating mode of the enterprise. Not only is RFID affected, but EPCGlobal is a non-profit organization that plans to build a vast “Internet of Things†around the world, which is the coding network for all the items that are in circulation. The Internet of Things, consisting of numerous servers, together with the current computer Internet and wireless communication network, constitutes a new generation of network systems. People, computers, and goods are accurately located on the network, and the concept of computing changes greatly.
