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.
