RFID Glossary : Chipless RFID tag
What is chipless RFID? A chipless RFID tag (also known as RF fibers) is one that does not make use of any integrated circuit technology to store information. The tag uses fibers or materials that reflect a portion of the reader's signal back; the unique return signal can be used as an identifier.
The fibers are shaped in different ways; thin threads, fine wires or even labels or laminates. At volume, they range in cost from ten cents to twenty-five cents per unit.
Chipless RFID tags can be used in many different 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.
Chipless tags 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.
