Plastic RFID Tags

This story described R&D work going on a Sunchon National University in South Korea to make a more receptive (but still passive) RFID tag.  The Korean researchers have had success in printing these tags using nanoparticle-polymer inks, but the obstacle of doing so at a cost below one cent per tag-the commercial threshold-remains.  Apparently, they are at the three cent per tag level.  This report, however, does not mention how a small, replaceable battery, could be designed into these plastic tags to make them “active.”  Currently, active RFID tags, used for Real Time Location Systems, cost in the neighborhood of $25 each.   MORE
