RFInDer

RFID stands for radio frequency identification, and is a way that a receiver can identify an item wirelessly within a certain range.  What I'd like to do is sell a product which uses RFID to help the user find items.  When the buyer opens the package it would contain 1 scanner and 10 RFID tags.  These tags are very small and come in all shapes and sizes.  The user could attach each tag to a different item that they are worried about losing.  Each tag would be assigned a number by the base unit for identification later.  At a later point if the user loses an item which they've tagged then they would be able to use the base unit (similar in form to a remote) to locate the item.  They'd do this by walking around the area they last had it and wait for the base to beep.  RFID has some detection on how far away a tag is so the base could essentially tell them hot (many beeps) or cold (few beeps).
