Researchers from the Sunchon National University, South Korea and Rice University, Houston have developed a radio frequency identification (RFID) tag that could replace the bar codes on groceries in stores. The tag, which can be directly printed on grocery items, uses ink containing carbon nanotubes that could instantly transmit information about the contents of a grocery cart.
