Re: Request for Presenters: In-Person Presentation of Credentials

Really interesting, thanks for the explanation of your use-case, James. I'm
curious:

Is it truly just the CBOR-LD VC Doc or is it a CBOR-LD Verifiable
Presentation (wrapped VC) that was serialized into a QR? I'm admittedly
"new here" so still learning, but wouldn't interoperable verification
software need the bundle as a verifiable presentation, not the standalone
credential?
