Trezor is a Bitcoin hardware wallet, which has just become available. It is difficult for novice users to relate to Bitcoin software, but a hardware wallet which can be compared to your DigiPass for banking transactions seems to go over quite well.
Trezor has no battery, wifi, bluetooth or radio, and only consist of two buttons. Corruption of this hardware Bitcoin wallet is very limited, comparable to cold storage. Not to mention it is incredibly small, so you can easily take it with you wherever you go.
