I plan to use a lot of chips while on vacation outside the US, and maybe send the cards home for safe keeping. What protection should I use to be 99.9% confident that a chip will get home with all the data intact & ready to upload? I expect to send them one at a time. One at a time means no total disasters. I hope.
crushing - possible, but protectable easily. I mostly understand about this.
EMP (electromagnetic pulse) messing up the memory - I _don’t_ understand how this might happen, nor how to protect against it.
Excess temperature - how high can these puppies go, in storage, anyway?
Mail theft - ship it from an official PO, trust the kindness of strangers. OK?
If there is a FAQ for this, please point me to it.
