In conjunction with a company called Plano, Microsoft is hoping to put its eggs in more than one basket. Beginning in the latter part of 2008, East Coast ShopRite Supermarkets will have grocery carts with consoles to help find products, then scan and pay for them without a need for humans. Users with loyalty cards can log into a site and submit a grocery list that will appear when they reach the store, complete with automatic coupons. While this sounds feasible, we suspect we will still forget one or two items between the site and the store.
