RFID tag It is the abbreviation of Radio Frequency Identification, which is a non-contact automatic identification technology. It automatically identifies target objects through radio frequency signals and can quickly track items and exchange data. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and identify multiple tags at the same time, making the operation quick and convenient. RFID technology was born during World War II. It is the successor of traditional barcode technology, also known as "electronic tag" or "radio frequency tag". The transmission range of RFID can reach several meters or even tens of meters.
As a wireless version of barcodes, RFID technology has the advantages that barcodes do not have, such as waterproofing, antimagnetic, high temperature resistance, long service life, large Reading Distance, the ability to encrypt data on labels, larger storage data capacity, and the ability to freely change stored information.
