Client: National Clearing House (KIR), operator of Szafir, Poland’s qualified electronic signature and trust service
Industry: Financial services
Scope: Full lifecycle product delivery (UX/UI, mobile, backend, integration) and 24/7 SLA support
Key technologies: Swift, Kotlin, Java, KMP, Jiffee
Challenge
KIR has long operated Szafir, enabling people to sign contracts, financial agreements, court filings, and other official documents with full legal validity across the EU. In 2018, KIR set out to make it available on smartphones, allowing users to complete the process without dedicated signing hardware.
The new service had to:
- Meet eIDAS, applicable ETSI standards, and supervisory requirements
- Protect sensitive cryptographic operations on mobile devices
- Support strong customer authentication without adding unnecessary friction
- Maintain the reliability expected of critical digital infrastructure
- Provide a simple and accessible user experience
Recognize some of these challenges from your own project?
Solution
Neontri developed mSzafir to extend KIR’s qualified electronic signature offering to smartphones.
Built on Jiffee, our platform for mobile payments, strong customer authentication, and operation authorization using one-time codes, the solution combined:
- Native iOS and Android applications with UX and UI designed around trust, clarity, and ease of use
- Backend services and integration components supporting the signing process
- Secure handling of cryptographic operations on mobile devices
- A high-availability architecture based on a private certificate authority
Delivery approach
Neontri supported mSzafir beyond the initial build, providing technical documentation for conformity assessments and regulatory audits, dedicated 24/7 SLA support, and continued product development after launch.
Results
mSzafir launched as one of the world’s first mobile qualified signature applications, extending KIR’s national trust infrastructure to a new channel without compromising security or regulatory compliance.
The platform passed statutory audits, met eIDAS and applicable supervisory requirements, and maintained 99.9% availability for mission-critical processes.
By enabling fully digital transactions at scale, mSzafir strengthened KIR’s position in Poland’s digital trust market.
