Interesting point from Sviokla: RFID requires a smart centre tracking dumb parts on the edge. Maybe this works for 80% of inventory, but it is the 20% that it doesn’t that causes all the problems. So smart “motes” might be the answer which add some smarts to the tricky 20% to feed them into the system that runs the 80%. This general idea – use a system that works for most everything and then innovate around the edges has to be a good rule of thumb.
