Blinking lights using RFID

In the ‘Why didn’t I think of that!’ category, a new purse tells its owners if important objects (keys, wallet, etc) are not inside it.

It works like this: a set of lights outside the bag are turned on by default. To each important item, a small RFID (radio frequency ID) chip is attached. If the item is placed in the purse, the lights system detects the attached RFID chip and turns off the corresponding lights. The prototype can handle up to three items, each having its own set of lights.

Is that cool or what? More info at the Discovery Channel.
