RF Fibers
RF fibers, also known as chipless RFID, is a kind of RFID tag that does not make use of any integrated circuit technology to store information. Fibers or materials are used that reflect a portion of the reader's signal back; the unique return signal can be used as an identifier.
Thin threads, fine wires or even labels or laminates - RF fibers are available in many forms. At volume, they range in cost from ten cents to twenty-five cents per unit.
RF fibers can be used in more environments than RFID tags with electronic circuitry. They tend to work over a wider temperature range; these tags also are less sensitive to RF interference.
RF fibers are sometimes used in anti-counterfeiting with documents. However, since the tags cannot transmit a unique serial number, they are less usable in the supply chain.
