There are some smart card hardware wallets with USB interfaces built in. One examples is the ledger wallet:

Here's a discussion thread about how to use it with electrum: https://bitcointalksearch.org/topic/ledger-nano-electrum-1348054

I don't know of any smartcard supporting crypto currencies.
Instead you may want to have a look at this hardware wallet survey:

I think smart cards do not need to support crypto currencies, only ECC key signatures, since it's the software's job to ultilize smart-card for that. Maybe you are right, that there may be nuances like HD wallet that may require more than just ECC key signing. I'll ask around the dev communities how far a way is a ECC-enabled smart-card to a non-displaying hardware wallet.
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.

Since you are on Linux be aware (at least for me and several other folks) that Electrum 2.6.4 is not connecting my Trezor under 64 bit. Windows users seem to be fine. Electrum works flawlessly until the Trezor is introduced. Read around and pick your hardware accordingly. I wish I had a bare metal linux OS to try my Trezor on, but I am using a VM. Wonder if that is a factor at all?
