Why QCassa

Regulation-ready. Quantum-safe. Hardware-backed.

A fiscal POS platform designed from the ground up for the next decade of payment security and Hungarian tax regulation.

NAV compliant

Designed for regulation 8/2025. NGM — the Hungarian Ministry of National Economy's electronic cash register framework. Type-approval submission in progress.

Post-quantum security

Key exchange and signatures based on NIST-selected post-quantum algorithms. Future-proof against cryptographically relevant quantum attacks — built in, not bolted on.

Hardware-backed

Keys live inside a Common Criteria EAL 4+ trusted execution environment, paired with a smart card for device identity and provisioning. Tamper-resistant by design.
