During a recent recording with André Facciolli (CEO, Netbr), Alan Kim Mareines (CEO, Lina), and Rodrigo Azevedo (Developer, Netbr), we saw a live demonstration that showed just how fast Open Finance data can be transformed into reusable digital credentials.
So why would an organization want to do this in the first place?
Netbr saw an opportunity to take data that banks in Brazil already maintain at a very high standard of accuracy and security, because they are legally required to, and make it useful outside the financial sector.
Instead of users re-entering personal information or submitting paper documents, those same bank-verified attributes can be turned into portable verifiable credentials that enterprises can trust immediately.
This approach addresses one of the biggest pains in identity management today: validating user data reliably without adding friction.
Rodrigo walked us through a proof of concept that Netbr and Lina built in only two weeks, a striking reminder of how quickly enterprises can move from idea to reality when combining Open Finance with verifiable credentials.
Watch the demo:
The demo in action:
- A user authenticates with their bank and consents to share registration data.
- That data is instantly turned into a verifiable credential and issued into a digital ID wallet.
- The credential is then used in real-world scenarios: proving you’re over 18 at a pub without revealing your birthdate, or checking into a hotel where verified attributes like name and address auto-fill the registration form.
These examples are just the beginning. Credentials can also power loyalty programs, reduce fraud in account openings, and even personalize services by using bank-verified data to tailor offers to a user’s actual financial profile.
The takeaway?
You no longer need to rely on physical copies of documents or manual form entry.
Instead, trusted, bank-verified data can be shared directly with verifiers.
Instantly, securely, and under the user’s full control.
Key concepts highlighted:
- Selective Disclosure: Users don’t need to overshare. They can prove “over 18 = true” without disclosing their full date of birth, or share only the attributes a hotel requires.
- Consented Data Use: Every credential begins with explicit user consent at the bank, embedding trust and compliance from the start.
- Simplified Model: This demo distilled verifiable credentials down to what really matters: data validation. Trusted attributes, presented simply, and solving a very common pain point.
- Wallet Flexibility: The credential wallet doesn’t have to be a standalone app. It can be white-labeled or embedded directly into an enterprise’s existing application, making adoption seamless.
The most powerful part of this demo wasn’t just the technology, it was the speed.
In just two weeks, a working system was up and running that shows how credentials can extend the value of Open Finance data far beyond banking, into everyday interactions.
