How can I generate a QR code for multiple outputs? I have an online store where users can pay with Bitcoin. I'd like them to send the total amount they have to pay to an QR code. From there on, the sent coins should be redistributed to two different wallet addresses in a 90%:10% ratio. How can I possibly do this?
BIP0021 (the contents of a QR code) does not specify a method for defining multiple addresses.
