I couldn't find this through Google. Normally one would expect a list on electrum's website. More specifically, since I am on Linux and with a computer that has a smart-card reader, I look for a smart-card that can plugin to my laptop directly. Of course the smart-card has to support ECC, however it seems most do.

If there isn't a ready choice, which one is the easiest to start hacking for a solution?

I also wish to know whether or not a ECC-supporting smart-card with software is a sufficient replacement for a hardware wallet.

Thanks.
