So how is your project better than what cryptosteel, bitkee , cryobit are doing?
You're just basically engraving letters and numbers on a metal sheet.
The rest is just fancy words.
I can do that in the nearby home depot for 5 euros.
Yeah I would agree in this. The project is good and I would like to carry a fancy card with me, but that's just it. It's just a fancy card with my private keys. If I'm never going to use to I would rather store them at a safe place than my pocket.
