if the *metal* plate were in a fire with this thing around it, this tamper thing wouldn't really work, and also, it could be imaged with an x-ray to read the fireproof seed card.
i would make it out of steel, line it with x-ray resistant lead on the inside, use a sheet of quartz glass for the viewer and make the beads from colored quartz glass.
the tamper resistance mechanism is pretty awesome, but it's ironic to make it out of plastic when the thing inside is fireproof.
I believe it's intended for a stack of washers....
I suppose you could surround them with a lead sleeve.🤔🧐😁
yeah, that would solve the x-ray imaging problem. i'm pretty sure devices like the ones used in airports, but with a higher resolution could give you the text on the rings if you image it at an angle and then stretch the image upwards (i mean like at a 2 degree angle or so).
If you EVER need to expatriate a stack, my money is on pattern recognition and recollection...
Just save your stack in your head, or better yet, a couple of heads...
