Cheaper RFID tag could replace bar codes in long-term care

Researchers have successfully printed flexible RFID tags directly onto paper. Investigators from South Korea's Sunchon National University and Rice University in Houston predicted the new process might soon allow tags to be made for less than a penny. This new technology could soon appear on residents' wristbands. And it might be a cost-effective alternative to the RFID tags that many facilities now use to manage inventory. The new tags use ink laced with carbon nanotubes to print electronics on paper or plastic that can instantly transmit information. While RFID tags are used widely in many settings, they are far more expensive to make.
