Chipless RFID

A chipless RFID tag (also known as RF fibers) is one that does not make use of any integrated circuit technology (silicon chips) 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 next ten years will see a rapid gain in market share of mainstream printed and chipless RFID tags. The biggest opportunity it provides is that we can tag each items because of the availability at low costs.

Advantages:

•         It can be used at higher temperature variations and are less sensitive to the RF Interference.
•         It can be printed directly on the packaging products for the cost around 45 paise.
•         It shows enhanced physical performance
•          It is capable of handling information up to 256 bits and can be maneuvered upto the distance of ten meters
•          As compared to the silicon chips the RFID's show enhanced physical performance too
•          It can capture data fast (approx 2 microseconds per bit) at 6 inches
•     It can read through materials such as paper, cardboard, plastics etc
