Hi! I've just updated my android offline "paper bitcoin client" - https://play.google.com/store/apps/details?id=ru.valle.btcNow it can not only to generate key-address pair, but also it can create and sign transactions using your private key, so now you can quite easily spend money from your paper wallet. Mini, brain wallet, WIF, WIF-compressed, BIP 38(both ec modes) private key formats are supported. Enjoy! sources: https://github.com/ValleZ/Paper-WalletNEW in version 2.2.0 - wallets printing, view QR codes and changing password for encrypted keys ps Check out the app's permissions ;-)

Any address with positive balance have unspent outputs (transactions). You have to obtain these transactions in raw form from bitcoin qt and paste it to the app. Then it would generate spending transaction (and verify it by itself) and after that you have to copy it and push it to bitcoin network by yourself using bitcoin qt or any other bitcoin service which allow to do that. It's quite easy. Most complicated thing is to obtain that unspent raw transaction.

I've added some new great stuff like BIP 38 encoding/decoding, qr code scanner, retrieving unspent transactions from blockchain.info (by copypasting from browser) and more!

It's just a bitcoin wallet without permission to use internet. It also doesn't store any information what you don't see on screen, so you have to keep your "wallet" (private keys) somewhere else, for example - in a written form on a paper. joethejudge77: Sorry, I'm working on automatic fee calculation and it have more obstacles than I thought. I need to design new UI elements for entering confirmations count and test it very carefully, so release will be a bit later.
