12. How do we currently originate digital credentials?
“Show me your passport, a
selfie, these other documents
from two years ago…”
You aka “holder” Bank aka “receiver”
Trusted
organisations
aka “issuers”
Govt Agency
Employer
Credit bureau
“Can I trust what’s in
these documents?”

13. This is expensive right now
Can’t have access because check
takes ~minutes ⏱ to ~weeks 📆

25. What else is cheqd doing
differently?

26. License issued in 2012
Schemas are used in digital credentials…and traditional ID docs
This becomes increasingly important in a world of Verifiable Credentials, where reliance on the
schema is a core part of the verifier being able to trust the a credential presented to them.
Schema attributes
https://creativecommons.org/licenses/by-sa/4.0/

27. License issued in 2012 License issued in 2015
new attributes in new format
Schemas regularly change over time
In this example, we have two driver’s licenses. The first is valid between 2012 and 2020, which
overlaps with the issuance of a new license format in 2015. In this scenario, systems will need to
understand and check the validity of both licenses and their associated schemas.

Schema issued in 2012 Schema issued in 2015
Schemas regularly change over time
If the initial schema is updated in a centralised registry such as schema.org, it may actually
overwrite and invalidate the old schema, making it very difficult for client applications and verifiers
to trust older or deprecated documents - which should still retain a high level of assurance.

29. This can be problematic for client apps
I can assure you
that this license
was valid in 2015
Computer says no…
We’ve all encountered some form of ‘Computer says no’ in this context. This could cause even
more headaches with Verifiable Credentials if we do not learn from previous mistakes..

36. Visual representations of credentials help users pick them out
In this example from British Airways, the
pass at the front is for a “Gold” loyalty
status member, whereas the pass at the
back is for a “standard” loyalty status
member.
This information can be represented in a
Verifiable Credential, of course, but the
example here uses the Apple Wallet /
Google Wallet formats to overlay a richer
display.

privacy-preserving digital
credentials fun and a daily habit?
