Implementation Considerations – Verification
What should I tell the end user when they present their credential for verification?
This page provides best practice guidance for verifying compact credentials presented in the following formats:
Original PDF generated by the issuer via MATTR VII API
Photograph/scanned image of the PDF
Screenshots/photos of the QR code
The following guide uses the example Working at Heights certificate. Design source files are made available for you to swap out images to your own credentials or to tweak the text where needed.
I have a digital PDF, Apple Wallet or Google Pay pass
Upload the original PDF recieved from the certificate issuer
Don’t take a screenshot of the PDF zoomed out, instead...
Enlarge the PDF so the QR code is in the centre of the screen, then take the screenshot
iOS:
Screenshot from Apple Wallet
Android:
Screenshot from Google Pay
iOS / Android: You don’t need to show the “details” page, that is for your own records only
I have a hard copy print out
Scan your hard copy pass in colour, at least 200dpi, and as a PDF or jpg file. Did that not work? Try taking a photo instead...
Take a photo of the QR code
Too far zoomed out. QR code is too small within the picture.
Avoid gloss lamination as it causes glare. Instead, use matte lamination.
Too dark and/or blurry. Try going to a brighter space or turning on the flash.
Out of focus. Try moving your camera back a bit until the QR code looks sharp.
