X509 signing or lots of outputs will make the QR code hard to scan. However, if all you want to do is send to a custom script (without using P2SH) I invite you to have a look at https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/ui/InputParser.java#L86 https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/util/Qr.java#L134 https://github.com/schildbach/bitcoin-wallet/blob/master/wallet/src/de/schildbach/wallet/util/Base43.java Basically it's "BITCOIN:-" plus the payment request in Base43 encoded form. I picked Base43, because that's optimized for QR codes.

The goal is to allow device to generate a multi-output payment request on its own, without relying on the server and x509 certificates. When scanned via QR code from, say, POS, it's pretty secure, so no additional authentication needed. > > I'd like something like this: > > bitcoin:?r=data:// > > If there's no standard for that, would it be a good idea to extend BIP72 this way? > ------------------------------------------------------------------------------ > Dive into the World of Parallel Programming The Go Parallel Website, sponsored > by Intel and developed in partnership with Slashdot Media, is your hub for all > things parallel software development, from weekly thought leadership blogs to > news, videos, case studies, tutorials and more.
