@banksycoin:

Yes I still have smartcard left for testing purpose. You can give me a shipping address by PM and I'll send one to you free of charge!
(Please note that you still need a smartcard reader to use it though)

@2112:

The SatoChip applet on the javacard should support Testcoin, however the BitcoinWallet implementation by ScripterRon only support Bitcoin.
The applet only manages the private keys, it has no knowledge of address or network. So basically any altcoin using the SECP256k1 could be used with it afaik. With minor changes, it should also be able to support NXT coin which uses Curve25519. The main difficulty is to integrate it in a particular wallet client... For testing purpose, there is a simple java library API (https://github.com/Toporin/SatoChipClient) that may provide some starting point...
