Hey, we have been building Keycard as an open-source, JavaCard hardware wallet for a couple of years.
Interesting to see another airtgapped device coming soon, I see shipping is expected to happen around Q4 of this year.
If I understand correctly, for €99 per-order we are getting Keycard Shell device and two plastic Keycards?
It would be super cool if Keycard Shell could be used for reading other smart cards also, to serve multiple functions.
