Secure authenticated document transfer for Hungary's central bank built on the same trust infrastructure as KAÜ

The Magyar Nemzeti Bank (MNB) is Hungary's central bank and primary financial regulator. It needed a secure, authenticated platform through which financial institutions could retrieve and transfer official electronic documents - regulatory publications, mandatory reporting, notifications - with the legal binding force that central bank communications require. The solution had to integrate with Hungary's government document authentication infrastructure and meet the security standards of the country's most sensitive financial institution.

E-Group built the MNB secure data transfer platform on its Digital Identity Platform - the same infrastructure that powers KAÜ, IDXaaS, and the MyD Wallet. The platform provides registration forms for financial institution access, electronic signature certificate management, access to MNB notifications and publications, mandatory reporting and data provision interfaces, announcement board systems, and full integration with AVDH - Hungary's central government notary service for document authentication - ensuring legally binding electronic document delivery.

The MNB platform is live in production, enabling financial institutions across Hungary to interact with the central bank through a secure, authenticated channel. The AVDH integration ensures every document transfer carries the same legal weight as a notarised exchange. Building this infrastructure for Hungary's central bank represents the apex of E-Group's financial trust portfolio - the same identity and cryptographic foundations used for national citizen authentication, now applied to the country's primary financial regulator.
