QES (Qualified Electronic Signature): Sign with absolute legal certainty.
When a signature needs to be incontrovertible, QES delivers. A Qualified Electronic Signature gives you the same legal standing as a handwritten signature across the EU – tied to a verified individual, created with certified technology, and backed by qualified certificates. IDnow QES reduces dispute risk, speeds up high-value signings, and keeps compliance defensible – so you can close complex agreements confidently and at scale.
Qualified assurance, tamper-proof trust.
QES is built for the moments where individual accountability matters. Unlike lighter signatures, QES links a signatory’s verified identity to the signature. The outcome is a tamper-evident, court-defensible signature that provides strong non-repudiation and the highest eIDAS-level assurance.
Deploy trust, your way.
All IDnow solutions provide maximum versatility, supporting every signature type (SES, AES, QES) across every channel: automated, expert-led video, Point-of-Sale, national eID / EUDI Wallet integrations and InstantSign for ultra-fast capture. That means you can run low-friction SES at scale today and seamlessly escalate to AES or QES when risk, regulation or business needs demand higher assurance – without re-engineering your stack. One integration, a single audit trail, consistent compliance evidence and unified reporting: the flexibility to match the right level of trust to each use case, geography and customer experience.
