What is RFID?

RFID radio frequency identification is a non-contact automatic identification technology. It uses RF signals to automatically identify the target object and obtain relevant data. It can work in various harsh environments without human intervention. RFID technology can recognize high-speed moving objects and recognize multiple tags at the same time for quick and convenient operations.
Ferguson, chief scientist at Accenture laboratory, believes that RFID is a breakthrough technology: "First, it can recognize a single very specific object, rather than recognizing only one type of object like a bar code. Second, it uses radio frequency to read data through external materials, while the barcode must be read by laser. Third, it can read multiple objects at the same time, while the barcode can only be read one by one. In addition, the storage information is also very large. "
