Now how many people would quit complaining about the checkout aisles at your local WalMart if you could just walk out the door? That is becoming closer to reality with the invention of a new RFID tag made from ink laced with carbon nanotubes.
You could run your cart by a detector and it tells you instantly whats in the cart, says James M. Tour of Rice University, whose research group invented the ink. No more lines, you just walk out with your stuff.
