RFID is the abbreviation of Radio Frequency Identification. The Chinese name is radio frequency identification technology. It is a technology that can automatically identify RFID tags and obtain data through radio frequency signals. The internal RFID tags can be directly read through the packaging. The identification work does not require human intervention. Greatly save manpower and material resources, and improve efficiency. In addition, because it can be identified without opening the package, and the label is not exposed directly, it can be used in various harsh environments. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient.
Four advantages of RFID:
First, it can identify individual objects, unlike barcodes that can only identify one type of object;
Second, the RFID tag can be built into the package, and the data can be read through the external package, and the barcode must be directly scanned to read the information;
Third, multiple objects can be identified at the same time, while the barcode can only be read individually.
Fourth, RFID can store a very large amount of information.
