Chipless RFID Tag

What is a Chipless RFID Tag?

Chipless tags are RFID tags without an integrated microchip. Chipless tags work by incorporating materials in the tag that reflect back a portion of the radio waves beamed at them from the reader. Chipless tags can be very cost effective and are increasingly being used in many applications. They can also be used in the supply chain to track products. However, these tags can be difficult to use in everyday life as they are incapable of transmitting unique serial number.
