Compliance Summary
InstantSign supports regulatory frameworks including the eIDAS Regulation (EU) No 910/2014 on electronic identification and trust services, where Qualified Electronic Signatures (QES) carry the same legal weight as handwritten signatures when preceded by compliant identity verification. The service integrates with qualified trust service provider (QTSP) certified identification schemes, enabling use of pre-identified User data including AML-compliant identification data. Evidence data storage is mandatory for QES issuance in accordance with eIDAS regulation. Therefore, InstantSign offers flexible electronic signature capabilities (QES, AES, SES), where customers must verify that chosen modules meet their specific regulatory requirements and ensure pre-identified User data complies with applicable QTSP-certified identification schemes when omitting the identification step.
