There’s a CNN story about talking shopping carts coming to a store year you. For some reason, this gave me an idea for RFID tags, if in fact the signal from them contains public information as simple as brand, expiration date, price, etc.
Someone could create a handheld device for consumers that would read the RFID tags from items you put in your cart and automatically tell you if the price is better somewhere else or perhaps even print a legit coupon. Let’s say you buy this device and a monthly service with it which allows you to use the device’s built-in wireless (?) to reach the service site and pull the coupons, which it may have scanned from the web or newspaper for you already.
It could even tell you if the expiration date on the cheese you’re buying is frighteningly close to the current date. Push a button and it will scan the nearby shelf for one that’s in better shape.
Probably all thought of before, but it’s something to think about.
