Doug, I do not know how many products have them now, but I suspect more than we know. For example, I recently learned that the recycle bins our county provides us has a RFID chip imbedded in them. Apparently the data collected from the chips let's the county know how often we put the bins out. RFID chips are being used more now because of the speed and ability to collect data on products being shipped and received, etc.
