What might an RFID-based future look like? Maybe it's a smart shopping cart that tallies your groceries as you shop and charges them to your credit
card so you don't have to wait in line to pay. Perhaps it's a refrigerator that can inventory its contents and suggest menus based on the ingredients
you have on hand. It could even be an RFID tag on your keychain that can tell you, "Hey, I'm underneath the sofa cushion."
