Title: Bitcoin Transaction through Printed QR-Codes? Post by: SaymonUno on March 19, 2012, 02:20:13 PM 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 Title: Re: Bitcoin Transaction through Printed QR-Codes?

Also see: https://www.bitaddress.org I have to go but I (or someone else) can explain a bit about how these work later. Title: Re: Bitcoin Transaction through Printed QR-Codes? Post by: Gabi on March 19, 2012, 03:05:23 PM 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 :) Title: Re: Bitcoin Transaction through Printed QR-Codes?

Post by: blastge on June 05, 2013, 04:10:19 AM WoW cool thx for the info. The built QR Code generator did not work. Can I use a QR Code generator (http://www.onbarcode.com/vb_net/qr-code-generator.html) like this? I googled and found this. I can also reset the barcode image (http://www.onbarcode.com/tutorial/vb-net-barcode-imaging.html).
