Radio Frequency Identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and specific targets . Radio frequency is generally microwave, 1-100GHz, suitable for short-distance identification communication. RFID readers are also divided into mobile and fixed ones. At present, RFID technology is widely used, such as libraries, access control systems, and food safety traceability.
The radio frequency tag is the physical carrier of the product electronic code (EPC), attached to the traceable item, can be circulated globally and can be identified and read and written. 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 as early as it was used to identify the identities of friendly and enemy aircraft in the Second World War. It became commercially available in the 1960s. RFID technology is an automatic identification technology. The U.S. Department of Defense stipulates that after January 1, 2005, all military supplies must use RFID tags; the U.S. Food and Drug Administration (FDA) recommends that pharmaceutical manufacturers use RFID to track routines from 2006 onwards. Falsified medicines. A series of actions such as the application of RFID technology by Walmart and Metro retail industry has promoted the upsurge of RFID application in the world. In 2000, the price of each RFID tag was $1. Many researchers believe that RFID tags are very expensive and can be applied on a large scale only if the cost is reduced. In 2005, the price of each RFID tag was about 12 cents, and now the price of UHF RFID is about 10 cents. RFID must be applied on a large scale, on the one hand, it is necessary to reduce the price of RFID tags, on the other hand, it depends on whether the application of RFID can bring value-added services. Statistics from the Eurostat office show that in 2010, 3% of EU companies applied RFID technology, which is used in ID documents and access control, supply chain and inventory tracking, car charging, anti-theft, production control, and asset management.
Conceptually, RFID is similar to barcode scanning. For barcode technology, it attaches the encoded barcode to the target and uses a dedicated scanning reader to use optical signals to transmit information from the bar magnet to scanning and reading. RFID uses a dedicated RFID reader and a dedicated RFID tag that can be attached to the target, and uses frequency signals to transmit information from the RFID tag to the RFID reader.
