Radio Frequency Identification (RFID) RFID is a non-contact automatic identification technology that uses radio frequency for non-contact two-way communication to automatically identify target objects (electronic tags) and acquire relevant data. It has high precision, strong environmental adaptability, and resistance. Strong interference, fast operation, no manual intervention for identification work, long service life, close reading distance (several centimeters to tens of meters), large amount of stored information, and high confidentiality (each electronic tag has unique features) The ID number), the ability to read and write without the need for a light source, the ability to read data through external materials, the ability to work in harsh environments, the ability to embed or attach to different types of products, and the ability to handle multiple labels simultaneously.
Ferguson, the chief scientist of Accenture Labs, believes that RFID is a breakthrough technology: "First, it can identify a single specific object, rather than identifying a certain type of object like a barcode. Second, it can be transmitted through radio frequency." External materials to read data, and barcodes must rely on lasers to read information; third, multiple objects can be read at the same time, and barcodes can only be read one by one. In addition, the amount of information stored is also very large."
