Question: What Are Some Other RFID Applications?

Ok, we all know about WalMart's inventory tracking systems, but what are other applications of RFID? Well I can think of a few. The first would be with moving companies. Think about it -- cross-country or international moves make for higher concerns for loss and theft. Also, when you get to the destination, unpacking boxes and placing them in the right rooms is a time waster. So, RFID could come to the rescue and make both processes a lot safer and more effective. What other applications can you think of?
