Free Idea # 261 - Locator chips with unique phone number

Invent tiny locator chips, each with its own unique phone number,
that would ring and vibrate when called. A locator chip could be
clipped on a key ring, inserted in a wallet, or glued to important
or valuable items that tend to go astray. Lost items could be
called from any phone. Users would just add 'keys' or 'glasses'
or 'iPod' to their cell phone contacts list.
