Before you choose

Consider

Coinkite TAPSIGNERThere is no card screen for independent review. Recovery needs the encrypted file, a separate copy of its printed decryption key and the wallet configuration; it takes place outside the card.

BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.

BitBox02This model cannot sign with an iPhone. BitBox02 Nova is a different model with iPhone support.
