RFID basic principle

What is the RFID

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 laboratory's 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 signals（active tag and to label or labels ）；to read information and understanding of the decoder after the central information systems to carry out the relevant data processing.

What makes retailers so highly RFID

Sanford Bernstein cristiano, according to analysts estimate the retailing company, by adopting the RFID, wal-mart can save $ billion each year, mostly because of the purchase of artificial view does not need to save the cost of labor code. Although some analysts think $8 billion in the digital too optimistic, but undoubtedly, RFID help solve the problem: the two biggest retail commodities and loss (broken by theft and supply chain was unsettled and loss of products),now a wal-mart, stealing a loss is almost 20 billion dollars, if a legitimate business turnover can achieve this number, can in American 1,000 enterprise's list of top first 694. Research organizations estimate, This rfid technology can help to reduce the level of 25% reduction and stock.

The typical application of RFID technology is what

Logistics and supply management

Manufacturing and assembly

Airline baggage handling

Mail/express parcel

A document tracking/library management

Animal identity tags

Movement

Access control/electronic tickets

Automatic charge. Road

RFID automatic recognition term explanation

·micro wave: wavelength of centimeters or frequency in 1-100GHZ electromagnetic wave.

·radiation frequency: usually microwave.
