Keep-Me-Close® is a small device that keeps a lost of personal belongings
It warns its owner whenever something is being left behind.
Implementation is straightforward. In the very near future many items will
contain an RFID chip (and if your personal belongings don't, than they can
be easily added). This chip contains a unique identifier.
The Keep-Me-Close® contains an RFID reader. Items can
be registered by keeping it close to the Keep-Me-CLose®. The device
continuously scans its surroundigns to see if all items registered are
still there. If not, it sounds an alarm, and shows the item that was
left behind on its display.

This is really the opposite of the
: keep informed when something gets
out of your reach, instead of when it gets within reach.
