More Daifuku
I just heard back from Daifuku and according to the Singapore representative, if there are air gaps between the tools, a hand-held scanner could still read the RFID tags. However, if the tools are just thrown in a toolbox and not separated (i.e., foam cutouts) the scanner/reader might not be able to distinguish between some of the tools.
Therefore for us, that would likely mean a major change of tool boxes for everyone and if the tool boxes are too large, they wouldn't be practical to take to remote work areas.
Back to the drawing board <grin>.
