WoW cool thx for the info.

No i didnt even install Bitcoin yet, building a secure system since 2 days (not so fast pc..) with virtualboxes and stuff, when im finnaly done i go get bitcoin lol

The built QR Code generator did not work. Can I use a QR Code generator like this? I googled and found this. I can also reset the barcode image.

If you want to walk on water, get out of the boat

Yes it's possible

And, did you try the Bitcoin client version 6?

http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.0/test/

It has a built in QR Code generator that do exactly what you are asking

All paid signature campaigns should be banned.

Here is something you might find interesting: https://bitcointalksearch.org/topic/printing-bitcoin-bills-55495

I have to go but I (or someone else) can explain a bit about how these work later.

hi,
heard about Bitcoin a few month ago but just a few moments ago i finnaly read some details about it.
Sounds really great, it could overthrow the power of banks lol.

Well my question is, is it possible to print a QR-Code with transaction details which would look like this [QR - 5 BTC] ?

If i understood it correct, after using this inside the QR-Code Bitcoin transfer the printed money will be useless and can be burned.

Well my vision was like that:

Open your Bitcoin programm.
- account balance 120 BTC

Klick on "Print BTC"
- choose amount
- ammount chosen = 5 BTC

Print out a paper which looks like that [QR - 5BTC] ;QR = QR Code with transaction details like the programm uses normally;)

*((Scan it to activate it
- it will make your balance go to 115 BTC))

Now go to a store, buy something worth 5 BTC, give the Paper to the Owner.

Now the Owner has 2 possible ways to use this printed money:
- Scan it to add 5 BTC to his balance (paper will be useless after this, can be burned) -- *and delete 5 BTC from Printers Account
- change the printed money to something worth of 5 BTC like you do with money now.

what ya think?

*is optional
