What is RFID

Radio Frequency Identification (RFID) is anon-contact automatic identification technology. RFID technology givesautomatic target recognition and access to relevant data via RF signal toidentify work without human intervention. RFID tagging system can work in harshenvironments, and can identify fast moving objects. The RFID chip can identifymultiple tags. The operation is convenient.

Accenture's chief scientist laboratoryFerguson believes RFID technology is a breakthrough:First, you canidentify individual's very specific objects, rather than as a class of objects thata bar code can only identify; second, With radio frequency, you can readinformation through the external material, which a barcode must rely on thelaser to read, and third, you can simultaneously read multiple objects, whichthe bar code can only read one by one . What is more, the RFID hardware has a verylarge amount of information stored.

HOW-RFID-WORK

What are the basic components of RFID?

The most basic RFID system consists ofthree parts:

  • Radio frequency identification tag (Tag): RFIDtags consist of the coupling components and chips, and is attached to object toidentify the target. Each tag has a unique electronic code.

  • RFID Reader: it is a radio frequency deviceto read (sometimes also write) tag information, and can be designed forhandheld or fixed.

  • RFID Antenna (Antenna): RFID tag antennafunctions to transmit RF signal between the tag and reader.

What is the basic principle of RFIDtechnology?

The basic principle of RFID technology isnot complicated: after the label enters into the magnetic field, RF signals whichis emitted by the receiver, would send out products information (Passive Tag, apassive tag or passive tags) in the chip by obtaining energy from inducedcurrent. Or forwardly send a certain frequency signal (Active Tag, active tagsor active tags). When RFID chip readers reads the information and decode,related information would be sent to a central information system.

Whatmakes retailers so worship applications of RFID technology?

According to an assessment of a retailanalyst at Sanford C. Bernstein's, with use of RFID technology, Wal-Mart couldsave $ 8.35 billion annually, because there is no need for manual work to checkthe bar code, which greatly help save labor costs. Although some analystsbelieve this figure - $ 8 billion is too optimistic, there is no doubt RFID systemcan help solve the two biggest challenges of retail: the supply shortage andwastage of goods (the loss of products due to theft and supply chain disturbed)Now the theft badly make Wal-Mart yearly lose almost $ 2 billion, if onecompany whose business turnover reach could reach this figure, it can rankitself 694 among the largest companies in the United States. Researchinstitutions estimate who uses RFID technology can help company save theft andinventory levels by 25%
