Excellent. Not a week ago, it occurred to me merchants aren't the ones who should have QR codes printed - people looking to spend BTC in the real world should print out small-denomination bills, and merchants just need a QR reader.
How is change handled? If I want to use such a bill to pay for something less than the sum held by the private key, is there a way for the merchant to easily return the change to another address I own, not linked to the private key printed on the bill?

I assume it's the private key that's under your finger. Without any additional security measures, how can one be sure that a paper coin is unspent?

Interested in the content under your finger .

very nice! Can I have them? 
I'm hoping yes... I'm planning on releasing the source code I used to print these.

Being my own bank. The first three real notes. Funded and ready to spend.
I have been modifying my Casascius Bitcoin Utility to accept a .png file in the same directory as the .exe, and use it as background artwork for the paper wallet generator feature.
