Life as a Physicist

My brother in-law and I had a great idea to help with people like me who are both frequent travelers and also leave things behind. In the future everything will be Radio Frequency Identified (RFID): clothing, books, electronic gadgets, computer power bricks, eye glasses, etc. These passive very small chips will identify themselves when queried by a central unit.

Here is how it would work: when done packing you’d put the RFID device in your suitcase and push the I’m about to leave button. It would scan every item close buy and make an item. If something key wasn’t close by — like your cell phone charger — it would complain. Then, when you are done packing at the hotel, you’d push the I’m returning button. It would complain if anything that was recorded when you left home wasn’t packed! This would definitely help me with those shirts I’ve left behind at hotel rooms because they fell down at the back of the closet!
