Chipless Technologies

For applications that require ultra low-cost sensors or extreme temperatures, it is not possible to use a silicon chip in the RFID tag. For such applications, TagSense offers unique Chipless RFID tags where the RFID data is encoded in the electromagnetic response of material structures. A very simple example of this type of RFID are the electronic security labels that are commonly used in retail stores for anti-theft (known as Electronic Article Surveillance or EAS). Chipless RFID should not be confused with Printed RFID Tags that are comprised of printed transistors.
TagSense also offers wideband RFID readers that are used to scan the chipless RFID tags and read the information. These chipless RFID readers are also generally useful for a wide range of electromagnetic measurements and HF antenna characterization.
