Bitcoin transfer through QR codes Ok, so let's say I have a wallet with 1 BTC in it. Is it possible to transfer that balance to a QR code or some type of barcode?

I want to know if it's possible to basically print out a piece of paper with a barcode or QR on it and physically hand it to someone else so they can scan the code and receive the coin the same way a giftcard works. 

Furthermore, is there a way to encode a giftcard with a specific amount of bitcoin so someone could then scan it and the BTC would be transferred to their wallet?
That's a paper wallet. Search for that. bitaddress.org or paperwallet.com are examples.

The way you intend to use it basically comes down to printing the private key part of a bitcoin wallet and giving that to someone else. Another use would be putting it in a safe so you can't get hacked.
