Sep 05, 2018
Radio Frequency Identification (RFID), also known as Radio Frequency Identification (RFID), is a communication technology that identifies specific targets and reads and writes related data through radio signals without the need to identify mechanical or optical contact between the system and a specific target. . For radio frequency, it is usually microwave, 1-100GHz, suitable for short-distance identification communication. RFID readers are also mobile and fixed. At present, RFID technology is widely used, such as: library, access control system, food safety trace ability.
The RF tag is the physical carrier of the Electronic Product Code (EPC) that attaches to traceable items and is globally circulated and identifiable and readable. RFID (Radio Frequency Identification) technology has attracted people's attention in recent years as a key technology for building the "Internet of Things". RFID technology originated in the United Kingdom and was used in the Second World War to identify the identity of enemy aircraft. It was commercialized in the 1960s. RFID technology is an automatic identification technology. The US Department of Defense stipulates that all military supplies must use RFID tags after January 1, 2005. The US Food and Drug Administration (FDA) recommends that drug manufacturers use RFID to track frequently from 2006. Counterfeit medicines. Walmart, Metro's retail application of RFID technology and other actions have promoted the application of RFID in the world. In 2000, the price of each RFID tag was $1. Many researchers believe that RFID tags are very expensive and can only be applied on a large scale if they are reduced in cost. In 2005, the price of each RFID tag was about 12 cents, and the price of UHF RFID is now about 10 cents. For large-scale application of RFID, on the one hand, it is necessary to reduce the price of RFID tags, and on the other hand, whether it can bring value-added services after applying RFID. According to statistics from the European Union Statistics Office, in 2010, 3% of companies in the European Union applied RFID technology, and their applications were distributed in identity documents and access control, supply chain and inventory tracking, car charging, anti-theft, production control, and asset management.
