FAQ

  • What is an EU Qualified Electronic Signature (QES)?

    A Qualified Electronic Signature (QES) is an advanced electronic signature that is legally recognized and has the same legal effect as a handwritten signature across the EU. You can find out more about QES here: https://sumsub.com/blog/electronic-signatures-qes/.

  • What is the difference between advanced and qualified electronic signatures?

    The main difference between an Advanced Electronic Signature (AES) and a Qualified Electronic Signature (QES) is their legal status and security level. A QES, created with a qualified device, has the same legal standing as a handwritten signature, while AES offers a slightly lower level of operational security and legal recognition within certain European countries.

  • How does the QES onboarding process work?

    The process involves ID Verification, Liveness, and QES signing, where an OTP is used to confirm the user's real-time presence. To complete the process, users must review the document, accept its content with a checkmark, and enter the OTP.

  • Is the QES legally recognized?

    Yes. Sumsub’s QES is fully compliant with the eIDAS Regulation and is legally recognized in all 27 EU member states, plus Iceland, Liechtenstein, and Norway. It carries the same legal effect as a handwritten signature and is accepted for cross-border onboarding and high-risk document signing.
