What is an electronically signed membership form?

A membership form is the founding contractual document by which a natural or legal person joins a mutual organization or collective provident contract. Advanced electronic signature (AES) eIDAS affixes a legally valid, timestamped and probative signature, replacing handwritten signature. It guarantees the signatory''s identity, content integrity and certain date. Compliant with article L221-2 of the Mutual Code, it applies to both individual memberships and collective company enrollment (ANI 2013). Since health data is a sensitive category (GDPR art. 9), Certyneo ensures their protection through encryption and qualified timestamp.
