I have an #Ellipal Titan and the battery scare me. The app also closed and controlled. That is why i was looking at the card no battery, nip, verified in app open source.
Ellipal is garbage too mate, why not invest in something free and open source?
Coinkite products are only "source viewable/verifiable".
SeedSigner
Blockstream Jade
Trezor
Bitbox
Foundation Passport
Those are all free & open source at various price ranges & feature sets.
& Again, for cold storage - no screen = no bueno.
