From Wikipedia – Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
A new RFID tag has been invented. Researchers at Sunchon National University in Suncheon, South Korea, and Rice University in Houston have built a RFID tag that can be printed directly onto 90% of groceries including potato chips, and cereal boxes.
You could run your cart by a detector and it tells your instantly what’s in the cart, says James M. Tour – Rice University
RFID tags are already being used in passports, books, and even on Toll roads like the IZoom in Indiana. Those RFID tags are expensive, at around $.50 a tag. The new RFID tags, reported by IEEE will be around $.03 to print.
According to ScienceNews.org, The new tags were made possible by the creation of semiconducting ink, which contains carbon nanotubes that will hold an electrical charge. I have to say, this is a huge leap for RFID tags, maybe we will start to see them everywhere.
