The only way IMVHO that microsignet could do it is if it is incorporated into each chip at the factory... and put where I showed them per the low-voltage and other sensor devices.
That is something i'v been expecting e.digital to deploy, a developed 'applicator/installer/keyer' to read a devices ICs layout an gather the best point in which to read it's signature/s.
But no - they'r looking at a fab plant to do it so that, like the algorithyms for nunchi, means the former because they can theorize it, but not do a POC... proof of concept; and of course why we're still at 6 cents.
