Trustless Physical Wallets

[Eli]

I'm thinking of developing a trustless physical wallet that can be sold over-the-counter and wondering what other projects out there that exist that do the same thing?

What technologies are available? I mean besides plain paper wallets that you can print on your own - stuff like bit-card.de which is pretty simple and requires trust int he manufacturer.

Could try and make something like Silver Wallets have going. Link: http://www.silverwallets.com/

You buy the physical coin, and then put your own address "on" it.
