Hi,

I wonder if there is a standard way to put Payment Request data into bitcoi= n: URI or directly into QR code. 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=3Ddata://<base64url-encoded-payment-request>

If there's no standard for that, would it be a good idea to extend BIP7= 2 this way?
