Think that the grocery store is safe from advertising spots and marketing ploys (ha!)? Think again, Batman. Later this year Microsoft will bring a new revolution to the traditional grocery store shopping cart system. Partnering with the Shop Rite supermarket chain, Microsoft will debut a new system that will allow customers to enter a shopping list from the comfort of their home computers. Once at the store the user can simply swipe their Shop Rite card, bringing up the previously entered list on a small screen embedded in the cart. How nice. Lest you think Microsoft and Shop Rite are looking to provide a purely selfless service, the new cart screens will be able to display advertising content as well. An embedded RFID chip will allow the cart screen to display different ad content depending on where in the store the cart is located. Sounds, well, pretty annoying. We’ll stick to Whole Foods, athankyou.
