The only reason things like Ledger exist is because regular smart cards (e.g. Yubikey) don't yet support the signature schemes used on blockchains.

- meehow 3y agoRegular smart cards also don't have screens, so it would mean totally blind signing. That's the problem which hardware wallets are solving, but sometimes the screen is just too small to show all the details of complex transactions.
