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

Hi Shawn,

Yes, absolutely right - it is a Verifiable Presentation.  We’re using the Digital Bazaar vpqr library:

https://github.com/digitalbazaar/vpqr

The project description for which is:

"Takes a Verifiable Presentation, compresses it via CBOR-LD, and turns it into a QR Code.”

Again the QR is NOT a link to a VC, but rather contains the entire VC.  The VC confirms the information that appears as text in the PDF.

The verfication web page displays the information that’s encoded in the VC (thereby confirming what appears in the text of the PDF).
