printed piggy bank

[jtimon]

Bitbills are suitable for saving. You can send bitcoins to the key pair printed inside of the card.
That could be made with free software without needing a trusted third party (just for saving, not for trading).
Is there any library that exports to QR code and imports back to the wallet?
Should it be included in the default client?

Would be nice if you could extract the keys and print them on paper then when you want to transact you scan them back to your computer and import to your wallet.
