Client

A large international bank offering services in daily banking, personal accounts, credit cards, savings, loans, leasing, investment, and insurance. With an extensive branch and partner network across Europe, the bank is known as one of Poland’s most innovative and technologically advanced institutions, particularly in the area of electronic banking.

Challenge

The bank sought to modernize its document signing process to improve efficiency and meet strict regulatory and security standards. Key challenges included:

  • The need for secure, legally recognized electronic document signing both inside and outside the organization.
  • Compliance with banking sector requirements, which mandated a qualified level of electronic signature for legal validity.
  • Reducing manual, paper-based correspondence that slowed communication and increased costs.

The goal was to implement a system that could securely handle document signing and validation for internal and external stakeholders while fully adhering to eIDAS standards.

Project journey

We designed and implemented a document handling system that initially supported standard electronic signatures, later enhanced with qualified electronic signatures for maximum legal assurance.

Key features included:

  • Full compliance with the EU eIDAS regulation, ensuring document authentication across all EU member states.
  • Two-way functionality, allowing the system to both validate incoming documents and sign outgoing ones.
  • Service-oriented architecture (SOA) enabling smooth integration with existing business applications — without major redevelopment or disruption.
  • Secure, automated document flow supporting high transaction volumes.

Results

  • Significant cost reduction, saving tens of thousands of euros monthly by replacing postal document handling with digital signatures.
  • Time savings for employees previously managing manual mailing and document processing.
  • Faster communication with external partners and clients through fully digital workflows.
  • Improved compliance and security aligned with EU-wide standards.
