Although RFID Tags (radio frequency identification) are used in other arenas of our lives--for example, libraries, traveling, etc.--they just might significantly change the face of grocery shopping. Researchers from Sunchon National University, South Korea, and Rice University, Houston, hold the optimistic belief that if they replace the existing bar code system with RFID grocery tags, checkout lines will be reduced significantly.

Essentially, RFID grocery tags, which will be printed directly onto food items, will instantly divulge the contents of a cart when put through a detector. Eliminating the need for individual scanning, RFID grocery tags utilize carbon nanotubes for easy checkouts.
