A paper bill is fine, but has one small problem. Unless you know exactly how much your purchase will be, there will be a balance left over on your paper bill. You can't just throw it away after an amount is swept off. You will need to move the balance to a secure address somehow. It would be great to have an automated way to make your bill expire after a predetermined set period of time and the balance is then moved to the next address in a series.

or just have a keyring or card with a qr where the merchant could return the change

I'm not sure I understand the difference between sweeping and importing a private key.

sweep = import + send amount to really private and secure key
