Re: I made my own Water/Fire-proof Metal Bitcoin Cold Storage, short guide.
Yes, again just a test piece. To save you time from typing in the address to check here's what's on the card:
Address: 1PiNodemHPYocq6dRw9JhN5f8N1nC2VfXQ
Privkey: 5KYbHUHB4Bwa87pEvBgb4Aqj6KsRjCGiuvgNCHruz698MNwQpDJ
You're welcome to anything on it 'cause I didn't put it there.
As for storage though it would be sensible to obscure the private key. Stop someone finding it and taking a picture/writing down the key. I was thinking a tamper proof label would achieve this? Any thoughts?
(It's a label that disintegrates when peeled, revealing "void" in the hologram)

Yes this is a good method. Using stainless steel is fine for resistance to corrosion and fire. Check the etching process digs into the metal, can use a torch to do that. Get the metal red hot, see if the characters survive. Might I suggest encrypting the keys, that way you don't care if anyone sees them? I think the protocol was BIP38. RE the scan QR code, what it really does is provide a backup - a 2nd copy of the dataset. Good idea, two copies. For that matter, why not a couple more. Better a couple copies of the card than the same time spent doing the front and back on one card.
