RFID potential uses and abuses

I decided to look in the patent database to find out what sort of patents might be out there for RFID technology development.

I only found one result which, funny enough, is for monitoring attendance. I was actually expecting to find something related to products and inventory tracking seeing as this is what is getting the attention in the popular media.

I find it interesting that the mass media is focussing on the inventory aspects while the only related patent I found was focussed on the human surveillance aspect, particularly where the patent is concerned with monitoring the length of time at the given device.
