RFID is the abbreviation for Radio Frequency Identification, called electronics label . What is the RFID technology? RFID recognition is a non-contact automatic identification technology, rf signal through its automatic target recognition and access to relevant data, identify work without manual intervention, it can work in various environments. RFID technology can identify high-speed moving objects and can identify multiple tags, the operation is fast and convenient. Accenture laboratorys chief scientist sir alex ferguson feels RFID is a breakthrough technology: first, can identify a very specific objects, rather like the code that can identify class objects; second, the use of rf, can read data through external materials, and bar code must rely on laser to read information; third, can also read on to multiple objects, and bar code can only read one by one. In addition, store of information is also very big. What is the basic component of RFID? The most basic RFID system consists of three parts: Tag:Tag consists of components and chips, each Tag has only electronic coding, adhere to the object for identifiering target; Reader:read (sometimes also can write) label information equipment,it can be designed for portable or fixed; Antenna: Transmit radio frequency signals between in the label and reader. The basic principle of RFID technology is what? The basic principle of RFID technology is not complex: Label into the field, Receive radio frequency signals from reader collision, with all the energy stored in a chip of the product information （ passive tag, there is no source label or labels ）, Or actively to send a frequency s
