For those of us who constantaly misplace our keys…Imagine having a credit card sized reciever which is placed in one’s wallet or purse and a small alarm type of device/key ring. As most people keep and or use their keys within close proximity to their pocket or purse. (such as when driving a car or unlocking a door. ) The alarm is triggered when the key ring and card are seperated by more then a few feet (5 to 10 ft.), preventing a person from ever misplacing their keys again! The device would be something like those used in such toys as furby’s, which detected the presence of another furby and allowed the furby’s to interact with one another .
