Due to an unfortunate error on my behalf I decided to post this so as to have some good come from this atrocity.

Nestled between two dense foam(?) bright green layers is a very thin black layer that houses the RFID chip.
The green layers have an extremely thin layer of chip clay on which the inlay can be heat sealed. I'm assuming the green has some kind of heat resistant property to protect the microchip.

Once fully apart the black encasement reveals the shape of the chip. All in all the microchip layer is an incredible 0.0195" thick! Unfortunately I couldn't find a way to pry apart the layers of the heat sealed, Area 51 inspired mystery composition of the black covering.

I really wanted to see the chip so .....

Other than the cooper ring I was able to peel up the microchip itself is more than just sandwiched between the layers of carbon-fibre. It has become part of them and alas remained a secret..

Thanks for sacrificing. Did you know it had an RFID or did you see it after the accident?

Thanks for posting. Nice photos. It's actually more involved than I would have thought.

It is both painful and embarrassing. I was attempting to mill out the center to accommodate a label. I have done soooo many already but with this one, in a split second I was drawn to look at my foot because of something I stepped on and *pop*. My damn Costanza'd elbow went off and blew through. Even at the lowest rpm possible the little heat generated makes the clay very supple. The weird layering of this particular chip didn't help either.

Isn't that how great discoveries are made though? By making "mistakes" :)
