that setup sounds very secure
then there would be only 2 more questions:
where do you store the plates?
do you have an inheritance option?

"where do you store the plates?"
I can't really say where I keep them but they are heat resistant to 1,600 C Celsius and the keys are encrypted. Even if you had one of the cards, it's useless to you.
do you have an inheritance option?
Yes. Someone has the relevant information to access these keys if anything ever happens to me.
sounds good
but i would like to have little redundant setup at best
you cant fly with the one guy backup
anymore
