Hungary runs its own national wallet ecosystem, the Digital Citizenship Programme (DÁP). If you serve customers in Hungary, two DÁP services are worth connecting: electronic identification from the DÁP digital wallet, and HAASZ, the consent-based data transfer service that brings authentic government data into your process instead of paper forms. TrustID Solutions implements both, from planning to production.
Hungarian citizens identify themselves with the digital wallet built into the DÁP application. We connect your service as a relying party: registration, certificates, the OpenID4VP flow and the cryptographic verifications that go with it. The same SDK serves the EUDI Wallets in the rest of Europe, so Hungary does not become a separate codebase.
Consent-based data transfer: with the customer’s approval and bound to a stated purpose, authentic government data arrives directly in your process: no paper forms, no manual entry, no subsequent corrections.
The HAASZ data service is not just a technical integration, but a direct business advantage. It helps make customer data management faster, more accurate and more predictable, while reducing manual administration and the number of errors.
This is especially valuable where you work with many customers, many data fields and time-sensitive processes. The more manual data entry and subsequent corrections there are, the greater the benefit from a well-implemented data service process.
Reduce the time spent requesting customer data and speed up the onboarding process.
Data arrives directly from authentic sources, with no manual recording needed.
Accurate, verified data reduces the number of subsequent corrections and reconciliations.
Data comes directly from government registries, guaranteeing its authenticity.
Fewer fields to fill in and a faster process.
Receive notifications when customer data changes, so your records stay current.
Data retrieval happens with the customer’s consent, tied to a specific purpose. After the customer approves the request, your system retrieves the data and feeds it into the business process, which takes paper-based and manual data collection out of the flow.
Your system asks for the data fields it needs and states the purpose they will be used for.
The customer sees exactly what is requested and why, and approves it in the DÁP application.
The approved data arrives from the government registry straight into your process, bound to the stated purpose.
If the customer’s registered data changes later, you receive a notification and your records stay current.

DÁP services are especially useful for organizations serving customers in Hungary, where fast and accurate handling of customer data is business-critical. These are typically services with a large number of customers who conduct digital administration: financial service providers, insurers, utility or telecommunications companies, and any organization where onboarding, contracting or data updates are frequent.
We don’t just help with the technical implementation, but also with making sure the connection generates real business value in your processes. Our goal is not to tick a compliance box, but to deliver a working, usable solution. TrustID Solutions provides support from implementation planning to integration, and helps ensure the solution fits your existing systems, processes and business goals.
Let’s look together at where connecting to the DÁP services can bring business benefits to your organization.
