Perspectives on Chipless RFID Technology

This chapter presents ongoing developments, as well as perspectives on chipless radio frequency identification (RFID) having to do with the idea of adding different functionalities to the chipless RFID tags. It describes four developments towards which chipless technology is oriented. The first development concerns the issue of the securing of information that will, in chipless RFID, be able to be processed in the “physical layer”. The second development describes the possibility of carrying out multiple readings. The chapter further introduces the chipless RFID sensor issue. It talks about the problem of rewriting information on a chipless tag. A potentially printable approach is introduced, and perspectives on this new solution are finally discussed.
