was going to say this type of system has got to be geared towards the avaition industry
IIRC, "Shadowing" of your tools in a tool box is an FAA requirement. This involves specifying a specific space for each tool. Kind of like Mom used to say about cleaning your room. Everything has it's place and everything should be in it's place.
The toolbox and drawers should be designed to quickly determine if a tool is missing, hence shadowing. You simply use some foam and cut out spots for each tool. A missing item is then outlined; it's quickly discovered as missing.
All the chip and RFID tagging is great, but it sure doesn't seem too practical for a guy like me, a shade-tree mechanic, who's got six boxes of varied tools all packed helter-skelter.
Shadowing seems a better way for me to go were I wanting to keep tight control over my miss-matched, mixed quality, tools. It's also a whole lot more economical a system than chipping and RFID'ing all the tools. But, a guy like me doesn't have an employer to provide the foam. That's a powerful lot of marking and cutting out foam outlines. Now if all my tools were Snap On, I may just change my mind. Till then, it's not worth the bother.
