Replacing the Checkout Line

Yet the Shopping Buddy does far more than ring up purchases. You can use its touch screen to order items from the supermarket deli; when your pastrami’s ready, the computer tells you to go pick it up. The Shopping Buddy automatically displays which aisle you’re in, what’s on sale there, and what you bought the last time you strolled through. If you can’t find an item, punch in its name on the touch screen and the Shopping Buddy will point you to the correct aisle. It’ll even display a “you are here” map that tracks you through the store like a homing device from a James Bond film. []
