Dad: Son, I just got my Coldcard hardware wallet today.

The bag is really special. Pretty sure it has more security feature than a banknote.

Son: Hi Dad,

Not sure about that one. ;-)

But yes, the device seems well protected. However, I recommend you download the latest firmware from Coinkite, check it and install it on your Coldcard manually. And also inspect the device visually, and verify the bag number.

Dad: Son, why all the effort, it is "just a calculator".

Son: Haha. Anyway, I will send you a tutorial later.
